x86/purgatory: Don't generate debug info for purgatory.ro
Purgatory.ro is a standalone binary that is not linked against the rest of
the kernel. Its image is copied into an array that is linked to the
kernel, and from there kexec relocates it wherever it desires.
Unlike the debug info for vmlinux, which can be used for analyzing crash
such info is useless in purgatory.ro. And discarding them can save about
200K space.
Original:
259080 kexec-purgatory.o
Stripped debug info:

x86/tsr: Fix tsc frequency enumeration bug on Lightning Mountain SoC
Frequency descriptor of Lightning Mountain SoC doesn't have all the
frequency entries so resulting in the below failure causing a kernel hang:
Error MSR_FSB_FREQ index 15 is unknown
tsc: Fast TSC calibration failed
So, add all the frequency entries in the Lightning Mountain SoC frequency
descriptor.
Fixes: 0cc5359d8fd45 ("x86/cpu: Update init data for new Airmont CPU model")

x86/acrn: Allow ACRN guest to use X2APIC mode
The ACRN Hypervisor did not support x2APIC and thus x2APIC support was disabled by always returning false when VM checked for x2APIC support. ACRN received full support of x2APIC and exports the capability through CPUID feature bits. Let VM decide if it needs to switch to x2APIC mode according to CPUID features.

Revert "x86/mm/64: Do not sync vmalloc/ioremap mappings"
This reverts commit 8bb9bf242d1fee925636353807c511d54fde8986. It seems the vmalloc page tables aren't always preallocated in all situations, because Jason Donenfeld reports an oops with this commit: BUG: unable to handle page fault for address: ffffe8ffffd00608 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP CPU: 2 PID: 22 Comm: kworker/2:0 Not tainted 5.8.0+ #154 RIP: process_one_work+0x2c/0x2d0 Code: 41 56 41 55 41 54 55 48 89 f5 53 48 89 fb 48 83 ec 08 48 8b 06 4c 8b 67 40 49 89 c6 45 30 f6 a8 04 b8 00 00 00 00 4c 0f 44 f0 <49> 8b 46 08 44 8b a8 00 01 05 Call Trace: worker_thread+0x4b/0x3b0 ? rescuer_thread+0x360/0x360 kthread+0x116/0x140 ? __kthread_create_worker+0x110/0x110 ret_from_fork+0x1f/0x30 CR2: ffffe8ffffd00608 and that page fault address is right in that vmalloc space, and we clearly don't have a PGD/P4D entry for it. Looking at the "Code:" line, the actual fault seems to come from the 'pwq->wq' dereference at the top of the process_one_work() function: struct pool_workqueue *pwq = get_work_pwq(work); struct worker_pool *pool = worker->pool; bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE; so 'struct pool_workqueue *pwq' is the allocation that hasn't been synchronized across CPUs. Just revert for now, while Joerg figures out the cause. Reported-and-bisected-by: Jason A.

This tree adds the sched_set_fifo*() encapsulation APIs to remove
static priority level knowledge from non-scheduler code. The three APIs for non-scheduler code to set SCHED_FIFO are: - sched_set_fifo() - sched_set_fifo_low() - sched_set_normal() These are two FIFO priority levels: default (high), and a 'low' priority level, plus sched_set_normal() to set the policy back to non-SCHED_FIFO. Since the changes affect a lot of non-scheduler code, we kept this in a separate tree. When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c, which can be resolved via: sched_set_fifo(ctlr->kworker_task); Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAl8pPQIRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1j0Jw/+LlSyX6gD2ATy3cizGL7DFPZogD5MVKTb IXbhXH/ACpuPQlBe1+haRLbJj6XfXqbOlAleVKt7eh+jZ1jYjC972RCSTO4566mJ 0v8Iy9kkEeb2TDbYx1H3bnk78lf85t0CB+sCzyKUYFuTrXU04eRj7MtN3vAQyRQU xJg83x/sT5DGdDTP50sL7lpbwk3INWkD0aDCJEaO/a9yHElMsTZiZBKoXxN/s30o FsfzW56jqtng771H2bo8ERN7+abwJg10crQU5mIaLhacNMETuz0NZ/f8fY/fydCL Ju8HAdNKNXyphWkAOmixQuyYtWKe2/GfbHg8hld0jmpwxkOSTgZjY+pFcv7/w306 g2l1TPOt8e1n5jbfnY3eig+9Kr8y0qHkXPfLfgRqKwMMaOqTTYixEzj+NdxEIRX9 Kr7oFAv6VEFfXGSpb5L1qyjIGVgQ5/JE/p3OC3GHEsw5VKiy5yjhNLoSmSGzdS61 1YurVvypSEUAn3DqTXgeGX76f0HH365fIKqmbFrUWxliF+YyflMhtrj2JFtejGzH Md3RgAzxusE9S6k3gw1ev4byh167bPBbY8jz0w3Gd7IBRKy9vo92h6ZRYIl6xeoC BU2To1IhCAydIr6hNsIiCSDTgiLbsYQzPuVVovUxNh+l1ZvKV2X+csEHhs8oW4pr 4BRU7dKL2NE= =/7JH -----END PGP SIGNATURE----- Merge tag 'sched-fifo-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull sched/fifo updates from Ingo Molnar: "This adds the sched_set_fifo*() encapsulation APIs to remove static priority level knowledge from non-scheduler code.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.
As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

hmm related patches for 5.9
This series adds reporting of the page table order from hmm_range_fault()
and some optimization of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault(). This
makes it easier to establish a large/huge/etc mapping in the device's
page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages. For instance migrating
pages to a device does not require the device to invalidate pages
already in the device.
- Update nouveau and hmm_tests to use the above

It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again for a
while. Unless we decide to switch to asciidoc or something...:)
- Lots of typo fixes, warning fixes, and more.

Merge tag 'docs-5.9' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS
URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again
for a while. Unless we decide to switch to asciidoc or
something...:)
- Lots of typo fixes, warning fixes, and more"

Support for FSGSBASE. Almost 5 years after the first RFC to support it,
this has been brought into a shape which is maintainable and actually works. This final version was done by Sasha Levin who took it up after Intel dropped the ball. Sasha discovered that the SGX (sic!) offerings out there ship rogue kernel modules enabling FSGSBASE behind the kernels back which opens an instantanious unpriviledged root hole. The FSGSBASE instructions provide a considerable speedup of the context switch path and enable user space to write GSBASE without kernel interaction. This enablement requires careful handling of the exception entries which go through the paranoid entry path as they cannot longer rely on the assumption that user GSBASE is positive (as enforced via prctl() on non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and exceptions) can still just utilize SWAPGS unconditionally when the entry comes from user space. Converting these entries to use FSGSBASE has no benefit as SWAPGS is only marginally slower than WRGSBASE and locating and retrieving the kernel GSBASE value is not a free operation either. The real benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes. The changes come with appropriate selftests and have held up in field testing against the (sanitized) Graphene-SGX driver. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8pGnoTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoTYJD/9873GkwvGcc/Vq/dJH1szGTgFftPyZ c/Y9gzx7EGBPLo25BS820L+ZlynzXHDxExKfCEaD10TZfe5XIc1vYNR0J74M2NmK IBgEDstJeW93ai+rHCFRXIevhpzU4GgGYJ1MeeOgbVMN3aGU1g6HfzMvtF0fPn8Y n6fsLZa43wgnoTdjwjjikpDTrzoZbaL1mbODBzBVPAaTbim7IKKTge6r/iCKrOjz Uixvm3g9lVzx52zidJ9kWa8esmbOM1j0EPe7/hy3qH9DFo87KxEzjHNH3T6gY5t6 NJhRAIfY+YyTHpPCUCshj6IkRudE6w/qjEAmKP9kWZxoJrvPCTWOhCzelwsFS9b9 gxEYfsnaKhsfNhB6fi0PtWlMzPINmEA7SuPza33u5WtQUK7s1iNlgHfvMbjstbwg MSETn4SG2/ZyzUrSC06lVwV8kh0RgM3cENc/jpFfIHD0vKGI3qfka/1RY94kcOCG AeJd0YRSU2RqL7lmxhHyG8tdb8eexns41IzbPCLXX2sF00eKNkVvMRYT2mKfKLFF q8v1x7yuwmODdXfFR6NdCkGm9IU7wtL6wuQ8Nhu9UraFmcXo6X6FLJC18FqcvSb9 jvcRP4XY/8pNjjf44JB8yWfah0xGQsaMIKQGP4yLv4j6Xk1xAQKH1MqcC7l1D2HN 5Z24GibFqSK/vA== =QaAN -----END PGP SIGNATURE----- Merge tag 'x86-fsgsbase-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fsgsbase from Thomas Gleixner: "Support for FSGSBASE.

entry/exit functionality based on the recent X86 effort to ensure correctness of entry/exit vs. RCU and instrumentation. As this functionality and the required entry/exit sequences are not architecture specific, sharing them allows other architectures to benefit instead of copying the same code over and over again. This branch was kept standalone to allow others to work on it. The conversion of x86 comes in a seperate pull request which obviously is based on this branch. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl8pCYsTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoY1MD/9VNT5ehFZwDBxX8EUY7QcBAPiR1yql XgHVbfhUe9Zta4q6eXn1A6IGpperY+2TLdU1Gm0aVXGAZwt5WeM7mAMIGpOXqibK oRZcTGOdxovY/548H3EWmrPAeJRKtpGDOF9MqmDfSBI4PXPyu9oKTRbWtRztgZa2 f8CALSXRCWRztZwI4xZKInC78p564Bz4x98wu/CbSZ7iTid/FIm4BcrH+eSbhLGt LUjKp74zDl4HncJUUCRv1RZmfiK4N0XwgfNLqHlkNu2ep1sJ92t4YuqyQC5acUUp L+fzlMdG1elFi5HlCmOTLrZIRerOyhqxfiWsfMiqapSvWdjW05HJ2AwyQbyhXMTt iLe8Rds0kcGGvCjt2X7S1mJFrPmV8QlrpQkOh9l/R5ekMsxG2jbzt7ZCbEASNtBp +riLLEQcl+IOej5zDAUUcdpWA8/ODlY9RZwv0vW9kR3v6SUtBdoS9YHSgbh5rgOt USEJwipyNLsD5tUWEIAZhw6moMzFFkO512O23bUgAwYKJx/KVYaBGWKq2nGLjqLc njqR3NX568/0ixPy3Vmhf3fde8Izp/CgK12gJxCj7sM77W8nvjD2IaqRsW2nK5Tk nD5yCLpolcl5vU8Bu0G9ln+jabKwbZHBOGFnqAUW0AKKv7jTkjILEoZbNVrd8MOG Sj/asNIIKw3LPg== =y2Ew -----END PGP SIGNATURE----- Merge tag 'core-entry-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull generic kernel entry/exit code from Thomas Gleixner: "Generic implementation of common syscall, interrupt and exception entry/exit functionality based on the recent X86 effort to ensure correctness of entry/exit vs RCU and instrumentation.

Time, timers and related driver updates:
- Prevent unnecessary timer softirq invocations by extending the tracking
of the next expiring timer in the timer wheel beyond the existing NOHZ
functionality. The tracking overhead at enqueue time is within the
noise, but on sensitive workloads the avoidance of the soft interrupt
invocation is a measurable improvement.
- The obligatory new clocksource driver for Ingenic X100 OST
- The usual fixes, improvements, cleanups and extensions for newer chip
variants all over the driver space.

Pull close_range() implementation from Christian Brauner:
"This adds the close_range() syscall. It allows to efficiently close a
range of file descriptors up to all file descriptors of a calling
task.
This is coordinated with the FreeBSD folks which have copied our
version of this syscall and in the meantime have already merged it in
April 2019:
https://reviews.freebsd.org/D21627
https://svnweb.freebsd.org/base?view=revision&revision=359836
The syscall originally came up in a discussion around the new mount
API and making new file descriptor types cloexec by default. During
this discussion, Al suggested the close_range() syscall.
First, it helps to close all file descriptors of an exec()ing task.
This can be done safely via (quoting Al's example from [1] verbatim):
/* that exec is sensitive */
unshare(CLONE_FILES);
/* we don't want anything past stderr here */
close_range(3, ~0U);
execve(....);
The code snippet above is one way of working around the problem that
file descriptors are not cloexec by default. This is aggravated by the
fact that we can't just switch them over without massively regressing
userspace. For a whole class of programs having an in-kernel method of
closing all file descriptors is very helpful (e.g. demons, service
managers, programming language standard libraries, container managers
etc.).
Second, it allows userspace to avoid implementing closing all file
descriptors by parsing through /proc/<pid>/fd/* and calling close() on
each file descriptor and other hacks. From looking at various
large(ish) userspace code bases this or similar patterns are very
common in service managers, container runtimes, and programming
language runtimes/standard libraries such as Python or Rust.
In addition, the syscall will also work for tasks that do not have
procfs mounted and on kernels that do not have procfs support compiled
in. In such situations the only way to make sure that all file
descriptors are closed is to call close() on each file descriptor up
to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery.
Based on Linus' suggestion close_range() also comes with a new flag
CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping
right before exec. This would usually be expressed in the sequence:
unshare(CLONE_FILES);
close_range(3, ~0U);
as pointed out by Linus it might be desirable to have this be a part
of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which
gets especially handy when we're closing all file descriptors above a
certain threshold.
Test-suite as always included"

Pull fork cleanups from Christian Brauner:
"This is cleanup series from when we reworked a chunk of the process
creation paths in the kernel and switched to struct
{kernel_}clone_args.
High-level this does two main things:
- Remove the double export of both do_fork() and _do_fork() where
do_fork() used the incosistent legacy clone calling convention.
Now we only export _do_fork() which is based on struct
kernel_clone_args.
- Remove the copy_thread_tls()/copy_thread() split making the
architecture specific HAVE_COYP_THREAD_TLS config option obsolete.
This switches all remaining architectures to select
HAVE_COPY_THREAD_TLS and thus to the copy_thread_tls() calling
convention. The current split makes the process creation codepaths
more convoluted than they need to be. Each architecture has their own
copy_thread() function unless it selects HAVE_COPY_THREAD_TLS then it
has a copy_thread_tls() function.
The split is not needed anymore nowadays, all architectures support
CLONE_SETTLS but quite a few of them never bothered to select
HAVE_COPY_THREAD_TLS and instead simply continued to use copy_thread()
and use the old calling convention. Removing this split cleans up the
process creation codepaths and paves the way for implementing clone3()
on such architectures since it requires the copy_thread_tls() calling
convention.
After having made each architectures support copy_thread_tls() this
series simply renames that function back to copy_thread(). It also
switches all architectures that call do_fork() directly over to
_do_fork() and the struct kernel_clone_args calling convention. This
is a corollary of switching the architectures that did not yet support
it over to copy_thread_tls() since do_fork() is conditional on not
supporting copy_thread_tls() (Mostly because it lacks a separate
argument for tls which is trivial to fix but there's no need for this
function to exist.).
The do_fork() removal is in itself already useful as it allows to to
remove the export of both do_fork() and _do_fork() we currently have
in favor of only _do_fork(). This has already been discussed back when
we added clone3(). The legacy clone() calling convention is - as is
probably well-known - somewhat odd:
#
# ABI hall of shame
#
config CLONE_BACKWARDS
config CLONE_BACKWARDS2
config CLONE_BACKWARDS3
that is aggravated by the fact that some architectures such as sparc
follow the CLONE_BACKWARDSx calling convention but don't really select
the corresponding config option since they call do_fork() directly.
So do_fork() enforces a somewhat arbitrary calling convention in the
first place that doesn't really help the individual architectures that
deviate from it. They can thus simply be switched to _do_fork()
enforcing a single calling convention. (I really hope that any new
architectures will __not__ try to implement their own calling
conventions...)
Most architectures already have made a similar switch (m68k comes to
mind).
Overall this removes more code than it adds even with a good portion
of added comments. It simplifies a chunk of arch specific assembly
either by moving the code into C or by simply rewriting the assembly.
Architectures that have been touched in non-trivial ways have all been
actually boot and stress tested: sparc and ia64 have been tested with
Debian 9 images. They are the two architectures which have been
touched the most. All non-trivial changes to architectures have seen
acks from the relevant maintainers. nios2 with a custom built
buildroot image. h8300 I couldn't get something bootable to test on
but the changes have been fairly automatic and I'm sure we'll hear
people yell if I broke something there.
All other architectures that have been touched in trivial ways have
been compile tested for each single patch of the series via git rebase
-x "make ..." v5.8-rc2. arm{64} and x86{_64} have been boot tested
even though they have just been trivially touched (removal of the
HAVE_COPY_THREAD_TLS macro from their Kconfig) because well they are
basically "core architectures" and since it is trivial to get your
hands on a useable image"

Last cycle setns() was changed to support attaching to multiple namespaces atomically. This requires all namespaces to have a point of no return where they can't fail anymore. Specifically, <namespace-type>_install() is allowed to perform permission checks and install the namespace into the new struct nsset that it has been given but it is not allowed to make visible changes to the affected task. Once <namespace-type>_install() returns, anything that the given namespace type additionally requires to be setup needs to ideally be done in a function that can't fail or if it fails the failure must be non-fatal. For time namespaces the relevant functions that fell into this category were timens_set_vvar_page() and vdso_join_timens(). The latter could still fail although it didn't need to. This function is only implemented for vdso_join_timens() in current mainline. As discussed on-list (cf. [1]), in order to make setns() support time namespaces when attaching to multiple namespaces at once properly we changed vdso_join_timens() to always succeed. So vdso_join_timens() replaces the mmap_write_lock_killable() with mmap_read_lock(). Please note that arm is about to grow vdso support for time namespaces (possibly this merge window). We've synced on this change and arm64 also uses mmap_read_lock(), i.e. makes vdso_join_timens() a function that can't fail. Once the changes here and the arm64 changes have landed, vdso_join_timens() should be turned into a void function so it's obvious to callers and implementers on other architectures that the expectation is that it can't fail. We didn't do this right away because it would've introduced unnecessary merge conflicts between the two trees for no major gain.

Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.

spi: Updates for v5.9
A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity. This pull
request includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the memory
subsystem doesn't seem to have a fixed maintainer at the minute and this
seemed like the most sensible way to get that hardware supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1.

ARM: new SoC support for v5.9
There are three SoC families newly dded to the 32-bit and
64-bit Arm architecture code in the kernel this time:
- Daniel Palmer adds initial support for two chips made by MStar, a
taiwanese SoC manufacturer that became part of Mediatek in 2012. For
now, the added support is fairly minimal, with just two of its
Cortex-A7 based 32-bit camera chips getting support for a limited
set of on-chip peripherals.
- Lars Povlsen from Microchip adds support for their new Sparx5
family of ethernet switch chips using 64-bit Cortex-A53 cores.
These are descended from earlier VSC7xxx SparX and Ocelot chips
using 32-bit MIPS cores.
- Daniele Alessandrelli from Intel adds support for the new Keem Bay
SoC for computer vision, built around a Movidius VPU with Linux
running on Arm Cortex-A53 cores.

ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory
subsystem and its drivers, starting out with a set of cleanup
patches.
A larger driver for the Tegra memory controller that was accidentally
missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware blobs
The tegra firmware driver gets extended to export some debug information
Various updates to i.MX firmware drivers, mostly cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space.
A new firmware based trusted platform module (fTPM) driver is added
based on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for identifying
a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device code.
There are also a number of updates to SoC specific drivers,
the main ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver

ARM: SoC changes for v5.9

ARM: SoC DT changes for 5.9
As usual, there are many patches addressing minor issues in existing
DTS files, such as DTC warnings, or adding support for additional
peripherals.
There are three added SoCs in existing product families:
- Amazon:
Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
otherwise known as AL73400 or first-generation Graviton, and following
the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips.
This one is added together with the official Evaluation platform.
- Qualcomm:
The Snapdragon SDM630 platform is a family of mid-range mobile phone
chips from 2017 based on Cortex-A53 or Kryo 260 CPUs.
A total of five end-user products are added based on these, all
Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and
XA2 Ultra.
- Renesas:
RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
family, and apparently closely related to the RZ/G2N and RZ/G2M
models we already support but has a faster GPU and additional
on-chip peripherals.
It is added along with the HopeRun HiHope RZ/G2H development board
A small number of new boards for already supported SoCs also debut:
- Allwinner sunxi:
Only one new machine, revision v1.2 of the Pine64 PinePhone
(non-Android) smartphone, containing minor changes compared to
earlier versions.
- Amlogic Meson:
WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
- Aspeed:
EthanolX is AMD's EPYC data center rerence platform, using an
ASpeed AST2600 baseboard management controller.
- Mediatek:
Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook
based on the MT8183 (Helio P60t) SoC.
- Nvidia Tegra:
ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
Thanks to PostmarketOS, these can now run mainline kernels
and become useful again.
The Jetson Xavier NX Developer Kit uses a SoM and carrier board
for the Tegra194, their latest 64-bit chip based on Carmel CPU
cores and Volta graphics.
- NXP i.MX:
Five new boards based on the 32-bit i.MX6 series are added:
The MYiR MYS-6ULX single-board computer, and four different
models of industrial computers from Protonic.
- Qualcomm:
MikroTik RouterBoard 3011 is a rackmounted router based on the
32-bit IPQ8064 networking SoC
Three older phones get added, the Snapdragon 808 (msm8992) based
Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
Windows Phone, and the Snapdragon 810 (msm8994) based Sony
Xperia Z5.
- Renesas:
In addition to the HiHope RZ/G2H board mentioned above, we gain
support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
RZ/G2N reference boards.
Beacon EmbeddedWorks adds another SoM+Carrier development board
for RZ/G2M.
- Rockchips:
Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it
is based on, using the high-end 32-bit rk3288 SoC.
Notable updates to existing platforms are usually for added on-chip
peripherals, including:
- ASpeed AST2xxx (various)
- Allwinner (cpufreq, thermal, Pinephone touchscreen)
- Amlogic Meson (audio, gpu dvdfs, board updates)
- Arm Versatile
- Broadcom (board updates for switch ports, Raspberry pi clock updates)
- Hisilicon (various)
- Intel/Altera SoCFPGA (various)
- Marvell Armada 7xxx/8xxx (smmu)
- Marvell MMP (GPU on mmp2/mmp3)
- Mediatek mt8183 (USB, pericfg)
- NXP Layerscape (VPU, thermal, DSPI)
- NXP i.MX (VPU, bindings, board updates)
- Nvidia Tegra194 (GPU)
- Qualcomm (GPU, Interconnect, ...)
- Renesas R-Car (SPI, IPMMU, board updates)
- STMicroelectronics STM32 (various)
- Samsung Exynos (various)
- Socionext Uniphier (updates to serial, and pcie)
- TI K3 (serdes, usb3, audio, sd, chipid)
- TI OMAP (IPU/DSP remoteproc changes, dropping platform data)
