@ -56,3 +56,12 @@ This file details changes in 2.6 which affect PCMCIA card driver authors:
memory regions in-use. The name argument should be a pointer to
your driver name. Eg, for pcnet_cs, name should point to the
string "pcnet_cs".
* CardServices is gone
CardServices() in 2.4 is just a big switch statement to call various
services. In 2.6, all of those entry points are exported and called
directly (except for pcmcia_report_error(), just use cs_error() instead).
* struct pcmcia_driver
You need to use struct pcmcia_driver and pcmcia_{un,}register_driver
instead of {un,}register_pccard_driver

Module for Digigram VX-Pocket 440 PCMCIA card.
ibl - Capture IBL size. (default = 0, minimum size)
Module supports up to 8 cards. The module is compiled only when
PCMCIA is supported on kernel.
To activate the driver via the card manager, you'll need to set
up /etc/pcmcia/vxp440.conf. See the sound/pcmcia/vx/vxp440.c.
When the driver is compiled as a module and the hotplug firmware
is supported, the firmware data is loaded via hotplug automatically.
Install the necessary firmware files in alsa-firmware package.
When no hotplug fw loader is available, you need to load the
firmware via vxloader utility in alsa-tools package.
About capture IBL, see the description of snd-vx222 module.
Note: the driver is build only when CONFIG_ISA is set.

Everything you ever wanted to know about Linux 2.6 -stable releases.
Rules on what kind of patches are accepted, and what ones are not, into
the "-stable" tree:
- It must be obviously correct and tested.
- It can not bigger than 100 lines, with context.
- It must fix only one thing.
- It must fix a real bug that bothers people (not a, "This could be a
problem..." type thing.)
- It must fix a problem that causes a build error (but not for things
marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
security issue, or some "oh, that's not good" issue. In short,
something critical.
- No "theoretical race condition" issues, unless an explanation of how
the race can be exploited.
- It can not contain any "trivial" fixes in it (spelling changes,
whitespace cleanups, etc.)
- It must be accepted by the relevant subsystem maintainer.
- It must follow Documentation/SubmittingPatches rules.
Procedure for submitting patches to the -stable tree:
- Send the patch, after verifying that it follows the above rules, to
stable@kernel.org.
- The sender will receive an ack when the patch has been accepted into
the queue, or a nak if the patch is rejected. This response might
take a few days, according to the developer's schedules.
- If accepted, the patch will be added to the -stable queue, for review
by other developers.
- Security patches should not be sent to this alias, but instead to the
documented security@kernel.org.
Review cycle:
- When the -stable maintainers decide for a review cycle, the patches
will be sent to the review committee, and the maintainer of the
affected area of the patch (unless the submitter is the maintainer of
the area) and CC: to the linux-kernel mailing list.
- The review committee has 48 hours in which to ack or nak the patch.
- If the patch is rejected by a member of the committee, or linux-kernel
members object to the patch, bringing up issues that the maintainers
and members did not realize, the patch will be dropped from the
queue.
- At the end of the review cycle, the acked patches will be added to
the latest -stable release, and a new -stable release will happen.
- Security patches will be accepted into the -stable tree directly from
the security kernel team, and not go through the normal review cycle.
Contact the kernel security team for more details on this procedure.
Review committe:
- This will be made up of a number of kernel developers who have
volunteered for this task, and a few that haven't.

Support the K8 IOMMU. Needed to run systems with more than 4GB of memory
Support the IOMMU. Needed to run systems with more than 3GB of memory
properly with 32-bit PCI devices that do not support DAC (Double Address
Cycle). The IOMMU can be turned off at runtime with the iommu=off parameter.
Normally the kernel will take the right choice by itself.
This option includes a driver for the AMD Opteron/Athlon64 IOMMU
and a software emulation used on some other systems.
If unsure, say Y.
# need this always enabled with GART_IOMMU for the VIA workaround

* and could pickup stale intr data when these CPUS are turned online.
*
* Not using broadcast is a cleaner approach IMO, but Andi Kleen disagrees with
* the idea of not using broadcast IPI's anymore. Hence the run time check
* is introduced, on his request so we can choose an alternate mechanism.
*
* Initial wacky performance tests that collect cycle counts show
* no increase in using mask v.s broadcast version. In fact they seem
* identical in terms of cycle counts.
*
* if we need to use broadcast, we need to do the following.
*
* cli;
* hold call_lock;
* clear any pending IPI, just ack and clear all pending intr
* set cpu_online_map;
* release call_lock;
* sti;
*
* The complicated dummy irq processing shown above is not required if
* we didnt sent IPI's to wrong CPU's in the first place.
