Pull x86 ACPI update from Peter Anvin:
"This is a patchset which didn't make the last merge window. It adds a
debugging capability to feed ACPI tables via the initramfs.
On a grander scope, it formalizes using the initramfs protocol for
feeding arbitrary blobs which need to be accessed early to the kernel:
they are fed first in the initramfs blob (lots of bootloaders can
concatenate this at boot time, others can use a single file) in an
uncompressed cpio archive using filenames starting with "kernel/".
The ACPI maintainers requested that this patchset be fed via the x86
tree rather than the ACPI tree as the footprint in the general x86
code is much bigger than in the ACPI code proper."

- image rotation and image effect functions.
- writeback and display output operations.
- M2M operation to crop, scale, rotation and csc.
The below is GSC hardware path:
Memory------->GSC------>Memory
FIMD--------->GSC------>HDMI
FIMD--------->GSC------>Memory
Memory------->GSC------>FIMD, Mixer
This driver is registered to IPP subsystem framework to be used by user side
and user can control the GSC hardware through some interfaces of IPP subsystem
framework.

This patch adds Image Post Processing(IPP) support for exynos drm driver.
IPP supports image scaler/rotator and input/output DMA operations
using IPP subsystem framework to control FIMC, Rotator and GSC hardware
and supports some user interfaces for user side.
And each IPP-based drivers support Memory to Memory operations
with various converting. And in case of FIMC hardware, it also supports
Writeback and Display output operations through local path.
Features:
- Memory to Memory operation support.
- Various pixel formats support.
- Image scaling support.
- Color Space Conversion support.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
- Writeback operation support to display blended image of FIMD fifo on screen
A summary to IPP Subsystem operations:
First of all, user should get property capabilities from IPP subsystem
and set these properties to hardware registers for desired operations.
The properties could be pixel format, position, rotation degree and
flip operation.
And next, user should set source and destination buffer data using
DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and
destinition buffers.
And next, user can control user-desired hardware with desired operations
such as play, stop, pause and resume controls.
And finally, user can aware of dma operation completion and also get
destination buffer that it contains user-desried result through dequeue
command.
IOCTL commands:
- DRM_EXYNOS_IPP_GET_PROPERTY
. get ipp driver capabilitis and id.
- DRM_EXYNOS_IPP_SET_PROPERTY
. set format, position, rotation, flip to source and destination buffers
- DRM_EXYNOS_IPP_QUEUE_BUF
. enqueue/dequeue buffer and make event list.
- DRM_EXYNOS_IPP_CMD_CTRL
. play/stop/pause/resume control.
Event:
- DRM_EXYNOS_IPP_EVENT
. a event to notify dma operation completion to user side.
Basic control flow:
Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator
or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and
destination buffers -> Command control(Play) -> Event is notified to User
-> User gets destinition buffer complated -> (Enqueue to source and
destination buffers -> Event is notified to User) * N -> Queue/Dequeue to
source and destination buffers -> Command control(Stop) -> Free gem handle
-> Close

With the new per-crtc locking mutliple set-cursor calls could happen
in parallel. Out of sheer paranoia I've opted for an irqsave spinlock.
But if there's indeed an access from interrupt contexts to these regs
it's already broken with the old code, so this can likely just be
reduced to a normal spinlock. Otoh the pageflip completion happens
from the vblank irq handler ...

This reverts commit f269ae0469fc882332bdfb5db15d3c1315fe2a10.
It turns out it causes a very noticeable interactivity regression with
CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
terminal window, while scrolling in a browser - the autogrouping means
that the two end up in separate cgroups, and the browser should be
smooth as silk despite the high load).
Says Paul Turner:
"It seems that the update-throttling on the wake-side is reducing the
interactive tasks' ability to preempt. While I suspect the right
longer term answer here is force these updates only in the
cross-cgroup case; this is less trivial. For this release I believe
the right answer is either going to be a revert or restore the updates
on the enqueue-side."

A NACK is probably the right thing. I was mostly converting a few
other drivers which used some simple, common patterns to use my new
common code, but this driver was missing it altogether. It looks like
there may be bigger issues, though, as you point out.

As noted earlier, I don't have much interest in this driver. I agree
that there are some other issues with the driver; I think it leaks
memory if it is ever allowed to unload, for one. Feel free to submit
an alternative patch to prevent this driver from being built as a
module.

Pull SPI updates from Grant Likely:
"Primarily SPI device driver bug fixes, one removal of an old driver,
and some new tegra support. There is some core code change too, but
all in all pretty small stuff.
The new features to note are:
- Common code for describing GPIO CS lines in the device tree
- Remove the SPI_BUFSIZ limitation on spi_write_the_read()
- core spi ensures bits_per_word is set correctly
- SPARC can now use SPI"

Merge emailed autofs cleanup/fix patches from Ian Kent
* autofs:
autofs4 - use simple_empty() for empty directory check
autofs4 - dont clear DCACHE_NEED_AUTOMOUNT on rootless mount
|
|
For direct (and offset) mounts, if an automounted mount is manually
umounted the trigger mount dentry can appear non-empty causing it to
not trigger mounts. This can also happen if there is a file handle
leak in a user space automounting application.
This happens because, when a ioctl control file handle is opened
on the mount, a cursor dentry is created which causes list_empty()
to see the dentry as non-empty. Since there is a case where listing
the directory of these dentrys is needed, the use of dcache_dir_*()
functions for .open() and .release() is needed.
Consequently simple_empty() must be used instead of list_empty()
when checking for an empty directory.

The DCACHE_NEED_AUTOMOUNT flag is cleared on mount and set on expire
for autofs rootless multi-mount dentrys to prevent unnecessary calls
to ->d_automount().
Since DCACHE_MANAGE_TRANSIT is always set on autofs dentrys ->d_managed()
is always called so the check can be done in ->d_manage() without the
need to change the flag. This still avoids unnecessary calls to
->d_automount(), adds negligible overhead and eliminates a seriously
ugly check in the expire code.

- Add necessary infrastructure to make balloon driver work under ARM.
- Add /dev/xen/privcmd interfaces to work with ARM and PVH.
- Improve Xen PCIBack wild-card parsing.
- Add Xen ACPI PAD (Processor Aggregator) support - so can offline/
online sockets depending on the power consumption.
- PVHVM + kexec = use an E820_RESV region for the shared region so we
don't overwrite said region during kexec reboot.
- Cleanups, compile fixes.

ARM, and there were changes next to the previous work-arounds that are
now gone.
