Add gamma via the DRM GAMMA_LUT/GAMMA_LUT_SIZE CRTC
properties. The expected LUT size is 4096 in order
to produce as accurate a set of segments as possible.
This version uses only the green channel's gamma curve
to set the hardware curve on DP550/650. For the sake of
simplicity, it uses the same table of coefficients for
all 3 curves on DP500.

Add a custom CRTC state struct to enable storing driver's private
state. This patch only adds the base drm_crtc_state struct and
the atomic functions that handle it.

Now that we are using a custom plane state in mali-dp, we need a
bespoke reset that takes into account the larger structure.

The newly introduced function causes a harmless build warning:
drivers/gpu/drm/arm/malidp_planes.c: In function 'malidp_plane_atomic_print_state':
drivers/gpu/drm/arm/malidp_planes.c:98:23: error: unused variable 'mp' [-Werror=unused-variable]
The variable serves no purpose here and can be removed.

Mali DP needs to have all the planes that are becoming inactive in the
new state disabled before re-enabling the active CRTC, otherwise we
start streaming out data from old pointers in memory.

Although we do check the completion-status of the request before
actually adding a wait on it (either to its submit fence or its
completion dma-fence), we currently do not check before adding it to the
dependency lists.
In fact, without checking for a completed request we may try to use the
signaler after it has been retired and its dependency tree freed:

Change "S_IRUSR | S_IWUSR" to "0600", it's easier to parse mentally.
This change should be part of commit 50f837371dd9 ("drm/vmwgfx: Revert
"drm/vmwgfx: Replace numeric parameter like 0444 with macro""), but the
patch was truncated somewhere in the patch route, so add the missing

This reverts commit 2d8e60e8b074 ("drm/vmwgfx: Replace numeric
parameter like 0444 with macro")
The commit belongs to the series of 1285 patches sent to LKML on
2016-08-02, it changes the representation of file permissions from
the octal value "0600" to "S_IRUSR | S_IWUSR".
The general consensus was that the changes does not increase
readability, quite the opposite; 0600 is easier to parse mentally
than S_IRUSR | S_IWUSR.

The hangcheck runs independently to the main flow of seqno through the
driver. However, we have an odd coupling of the seqno reset that is
unwelcome, and if poked at just the right rate can cause spurious hangs
(e.g. gem_exec_whisper) on an apparently idle engine.

The contents of a ring are only valid between HEAD and TAIL, when the
ring is idle (HEAD == TAIL) we can simply let the pages go under memory
pressure if they are not pinned by an active context. Any new content
will be written after HEAD and so the ring will again be valid between
HEAD and TAIL, everything outside can be discarded.
Note that we take care of ensuring that we do not reset the HEAD
backwards following a GPU hang on an idle ring.
The same precautions are what enable us to use stolen memory for rings.

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.
I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.
Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.
To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Backmerge Linux 4.11-rc7 from Linus tree, to fix some
conflicts that were causing problems with the rerere cache
in drm-tip.
|
|
Previously with commit a9c1f90c8e17
("drm/i915: Don't mask EI UP interrupt on IVB|SNB") certain,
seemingly unrelated bit (GEN6_PM_RP_UP_EI_EXPIRED) was needed
to be unmasked for IVB and SNB in order to prevent system hang
with chained batchbuffers.
Our CI was seeing incomplete results with tests that used
chained batches and it was found out that HSW needs to have this
same bit unmasked to reliably survive chained batches.
Always unmask GEN6_PM_RP_UP_EI_EXPIRED on Haswell to
prevent system hang with batch chaining.

testing would have caught before merging. The next change that is
borderline too big for a late rc is switching the device-dax locking

The __copy_user_nocache fix will have a full replacement in 4.12 to
move those pmem special case considerations into the pmem driver. The

our error clearing support for btt went in broken, so we just disable
it in 4.11 and -stable. A replacement / full fix is in the pipeline
for 4.12

The copy_page is optimized memcpy for page-alinged address. If it is
used with non-page aligned address, it can corrupt memory which means
system corruption. With zram, it can happen with
1. 64K architecture
2. partial IO
3. slub debug
Partial IO need to allocate a page and zram allocates it via kmalloc.
With slub debug, kmalloc(PAGE_SIZE) doesn't return page-size aligned
address. And finally, copy_page(mem, cmem) corrupts memory.
So, this patch changes it to memcpy.
Actuaully, we don't need to change zram_bvec_write part because zsmalloc
returns page-aligned address in case of PAGE_SIZE class but it's not
good to rely on the internal of zsmalloc.
Note:
When this patch is merged to stable, clear_page should be fixed, too.
Unfortunately, recent zram removes it by "same page merge" feature so
it's hard to backport this patch to -stable tree.
I will handle it when I receive the mail from stable tree maintainer to
merge this patch to backport.

If link training at a link rate optimal for a particular
mode fails during modeset's atomic commit phase, then we
let the modeset complete and then retry. We save the link rate
value at which link training failed, update the link status property
to "BAD" and use a lower link rate to prune the modes. It will redo
the modeset on the current mode at lower link rate or if the current
mode gets pruned due to lower link constraints then, it will send a
hotplug uevent for userspace to handle it.
This is also required to pass DP CTS tests 4.3.1.3, 4.3.1.4,
4.3.1.6.
This patch is a resend of the original commit id (233ce881dd91fb
"drm/i915: Implement Link Rate fallback on Link training failure")
which got reverted in this commit id (afc1ebf4562a14 Revert
"drm/i915: Implement Link Rate fallback on Link training failure")
due to CI failures.
After investigating the CI failures it was found that these
were essentially the failures which were always there but hidden because
they used to be DRM_DEBUG_KMS messages for link failures so never got
caught by CI. But now this patch actually throws DRM_ERROR if the link
training fails at RBR and 1 lane. So it caught these link train failures.
There were two failures:
1. On SKL 6700k this was because the machine in CI lab is a SKL desktop
without eDP on Port A. But our VBT initialization code in the driver writes
VBT defaults in a way that it always sets DP flag on Port A and this does
not get cleared after parsing the VBT outputs. This has been fixed in
commit id (bb1d132935c2f8 "drm/i915/vbt: split out defaults that are set
when there is no VBT) and (665788572c6410b "drm/i915/vbt: don't propagate
errors from intel_bios_init())
2. On ILK-650 desktop - This was happening because of a bad monitor desktop
combination. I switched the monitor in the CI lab and that helped get rid
of the link failures on ILK system.
v10:
* Rebase on drm-tip and resend after revert
v9:
* Use the trimmed max values of link rate/lane count based on
link train fallback (Daniel Vetter)
v8:
* Set link_status to BAD first and then call mode_valid (Jani Nikula)
v7:
Remove the redundant variable in previous patch itself
v6:
* Obtain link rate index from fallback_link_rate using
the helper intel_dp_link_rate_index (Jani Nikula)
* Include fallback within intel_dp_start_link_train (Jani Nikula)
v5:
* Move set link status to drm core (Daniel Vetter, Jani Nikula)
v4:
* Add fallback support for non DDI platforms too
* Set connector->link status inside set_link_status function
(Jani Nikula)
v3:
* Set link status property to BAd unconditionally (Jani Nikula)
* Dont use two separate variables link_train_failed and link_status
to indicate same thing (Jani Nikula)
v2:
* Squashed a few patches (Jani Nikula)

Telit LE920A4 uses the same pid 0x1201 of LE920, but modem
implementation is different, since it requires DTR to be set for
answering to qmi messages.
This patch replaces QMI_FIXED_INTF with QMI_QUIRK_SET_DTR: tests on
LE920 have been performed in order to verify backward compatibility.

Revert commit 57707a9a7780 (ACPICA: Resources: Not a valid resource if
buffer length too long) as it is reported to prevent the TPM module
from loading on Lenovo X60 with Coreboot.
It also causes new confusing warnings to show up in the kernel log.

Pull pin control fixes from Linus Walleij:
"Two pin control fixes arriving late, these are hopefully the last pin
control fixes I send this kernel cycle. A Chromebook and an Exynos SoC
thingie.
The Exynos patch is pretty big, it is fixing unbroken a breakage
caused by yours truly when trying to figure out the merge mess with
the different Samsung platforms for this merge window. Sorry about
that. We have countered this situation by assigning a Samsung pin
control submaintainer to catch stuff earlier.
Summary:
- Make the Acer Chromebook keyboard work again with the Intel
Cherryview driver.
- Fix a merge error in the Exynos 5433 driver"
* tag 'pinctrl-v4.11-5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
pinctrl: cherryview: Add a quirk to make Acer Chromebook keyboard work again
pinctrl: samsung: Add missing part for PINCFG_TYPE_DRV of Exynos5433
