Imre Deak 300efa9eea drm/i915: Fix hibernation with ACPI S0 target state
After

commit dd9f31c7a3
Author: Imre Deak <imre.deak@intel.com>
Date:   Wed Aug 16 17:46:07 2017 +0300

    drm/i915/gen9+: Set same power state before hibernation image
    save/restore

during hibernation/suspend the power domain functionality got disabled,
after which resume could leave it incorrectly disabled if the ACPI
target state was S0 during suspend and i915 was not loaded by the loader
kernel.

This was caused by not considering if we resumed from hibernation as the
condition for power domains reiniting.

Fix this by simply tracking if we suspended power domains during system
suspend and reinit power domains accordingly during resume. This will
result in reiniting power domains always when resuming from hibernation,
regardless of the platform and whether or not i915 is loaded by the
loader kernel.

The reason we didn't catch this earlier is that the enabled/disabled
state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform
and kernel config dependent: on my SKL the target state is S4
during PMSG_FREEZE and (with the driver loaded in the loader kernel)
S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during
PMSG_FREEZE but (contrary to this) power domains are not initialized
during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or
it's loaded but without the DMC firmware being available.

Chris Wilson 76cb9d314a drm/i915/execlists: Use a locked clear_bit() for synchronisation with interrupt
We were relying on the uncached reads when processing the CSB to provide
ourselves with the serialisation with the interrupt handler (so we could
detect new interrupts in the middle of processing the old one). However,
in commit 767a983ab2 ("drm/i915/execlists: Read the context-status HEAD
from the HWSP") those uncached reads were eliminated (on one path at
least) and along with them our serialisation. The result is that we
would very rarely miss notification of a new interrupt and leave a
context-switch unprocessed, hanging the GPU.

If the GPU is stuck waiting for an event or for a semaphore, we need to

which engines we want reset, but we were still using the old interface

Dhinakaran Pandiyan 7a7d58dc29 drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.
If bios sets up an MST output and hardware state readout code sees this is
an SST configuration, when disabling the encoder we end up calling
->post_disable_dp() hook instead of the MST version. Consequently, we write
to the DP_SET_POWER dpcd to set it D3 state. Further along when we try
enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up
the MST hub. This results in continuous link training failures which keep
the system busy delaying boot. We could identify bios MST boot discrepancy
and handle it accordingly but a simple way to solve this is to write to the
DP_SET_POWER dpcd for MST too.

to accept the garbage in. We'll just ignore any of the bits we
don't want. The mode type is just a hint anyway, and more
useful for the kernel->userspace direction.

Arnd Bergmann 37efe80ce8 drm/vmwgfx: use monotonic event timestamps
DRM_VMW_EVENT_FENCE_SIGNALED (struct drm_vmw_event_fence) and
DRM_EVENT_VBLANK (struct drm_event_vblank) pass timestamps in 32-bit
seconds/microseconds format.

As of commit c61eef726a ("drm: add support for monotonic vblank
timestamps"), other DRM drivers use monotonic times for drm_event_vblank,
but vmwgfx still uses CLOCK_REALTIME for both events, which suffers from
the y2038/y2106 overflow as well as time jumps.

For consistency, this changes vmwgfx to use ktime_get_ts64 as well,
which solves those problems and avoids the deprecated do_gettimeofday()
function.

This should be transparent to to user space, as long as it doesn't
compare the time against the result of gettimeofday().

Thomas Hellstrom 20fb5a635a drm/vmwgfx: Unpin the screen object backup buffer when not used
We were relying on the pinned screen object backup buffer to be destroyed
when not used. But if we hold a copy of the atomic state, like when
hibernating, the backup buffer might not be destroyed since it's
refcounted by the atomic state. This causes us to hibernate with a
buffer pinned in VRAM.

Fix this by only having the buffer pinned when it is actually used by a
screen object.

For legacy surfaces, they were previously registered as device resources
when the driver resources were created. Since they are evictable we instead
register them as device resources once they are created on the device,
just like for guest-backed surfaces. This has implications during
hibernation where we can't hibernate with device resources active.

Thomas Hellstrom bf833fd36f drm/vmwgfx: Avoid pinning fbdev framebuffers
fbdev framebuffers were previously pinned to be able to keep them mapped
across updates.

This commit introduces a mechanism that instead revalidates the map on
each update, keeping the map cached across updates. The cached map is torn
down if the underlying pages change. Typically on buffer object moves and
swapouts.

This should be nicer to the system when we have resource contention.

Thomas Hellstrom 79273e1b7e drm/vmwgfx: Add a cpu blit utility that can be used for page-backed bos
The utility uses kmap_atomic() instead of vmapping the whole buffer
object. As a result there will be more book-keeping but on some
architectures this will help avoid exhausting vmalloc space and also
avoid expensive TLB flushes.

The blit utility also adds a provision to compute a bounding box of
changed content, which is very useful to optimize presentation speed
of ill-behaved applications that don't supply proper damage regions, and
for page-flips. The cost of computing the bounding box is not that
expensive when done in a cpu-blit utility like this.

Evan Quan f0c2b16ba8 drm/amdgpu: no job timeout setting on compute queues
Under some heavy computing environment(e.g. dgemm test), it
takes the asic over 10+ seconds to finish the dispatched job
which will trigger the timeout.

It's quite confusing although it does not seem to bring any
real problems. As a quick workround, we choose to not enfoce
the timeout setting on compute queues.

Greg Kroah-Hartman c50099f856 Update extcon for 4.17
Detailed description for this pull request:
 1. Add exported extcon function in order to support OF graph binding
 - The extcon consumer driver used the "extcon = <&extcon's phandle"
   property in device-tree in order to bind between extcon provider
   and consumer driver. But, OF graph method is better than 'extcon' property.
   So, extcon subsystem adds the following function to support OF graph binding.
   : extcon_find_edev_by_node(struct device_node *node)
 
 - Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
   and device-tree subsystem. This immutable branch contains the use-case of
   OF graph binding for EXTCON_HDMI connector between MHL device driver
   and extcon provider driver.
 
 2. Fix minor issues of extcon device drivers
 - Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
 - Remove workaround code for id pin direction from extcon-inte-int3496.c
   because GPIO ACPI library does support it with generic way.
 - Set direction and drv flags for V5 boost GPIO because of fixing
   the firmware bug.

Merge tag 'extcon-next-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next

Chanwoo writes:

Update extcon for 4.17

Detailed description for this pull request:
1. Add exported extcon function in order to support OF graph binding
- The extcon consumer driver used the "extcon = <&extcon's phandle"
  property in device-tree in order to bind between extcon provider
  and consumer driver. But, OF graph method is better than 'extcon' property.
  So, extcon subsystem adds the following function to support OF graph binding.
  : extcon_find_edev_by_node(struct device_node *node)

- Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
  and device-tree subsystem. This immutable branch contains the use-case of
  OF graph binding for EXTCON_HDMI connector between MHL device driver
  and extcon provider driver.

2. Fix minor issues of extcon device drivers
- Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
- Remove workaround code for id pin direction from extcon-inte-int3496.c
  because GPIO ACPI library does support it with generic way.
- Set direction and drv flags for V5 boost GPIO because of fixing
  the firmware bug.

Thomas Hellstrom 73a88250b7 drm/vmwgfx: Fix a destoy-while-held mutex problem.
When validating legacy surfaces, the backup bo might be destroyed at
surface validate time. However, the kms resource validation code may have
the bo reserved, so we will destroy a locked mutex. While there shouldn't
be any other users of that mutex when it is destroyed, it causes a lock
leak and thus throws a lockdep error.

Fix this by having the kms resource validation code hold a reference to
the bo while we have it reserved. We do this by introducing a validation
context which might come in handy when the kms code is extended to validate
multiple resources or buffers.

Thomas Hellstrom 140bcaa23a drm/vmwgfx: Fix black screen and device errors when running without fbdev
When we are running without fbdev, transitioning from the login screen to
X or gnome-shell/wayland will cause a vt switch and the driver will disable
svga mode, losing all modesetting resources. However, the kms atomic state
does not reflect that and may think that a crtc is still turned on, which
will cause device errors when we try to bind an fb to the crtc, and the
screen will remain black.

Fix this by turning off all kms resources before disabling svga mode.

 Planes will now also export the IN_FORMATS property by supporting the

 Other than that, there's a bit of cleanup of DMA API abuse, use of the
 private object infrastructure for global state (rather than subclassing
 atomic state objects) and an implementation of ->{begin,end}_cpu_access
 callbacks for PRIME exported buffers, which allow users to perform cache
 maintenance on these buffers.

 the framebuffer is removed.
 
 Furthermore this contains a fix for a crash on IOMMU detach at driver
 unbind time and a regulator enable/disable unbalance fix.

drm/tegra: Fixes for v4.16-rc7

This contains two small fixes for the alpha blending support that was
merged into v4.16-rc1 and a fix for connector reference leaks caused by
the fact that display pipelines are no longer automatically disabled if
the framebuffer is removed.

Furthermore this contains a fix for a crash on IOMMU detach at driver
unbind time and a regulator enable/disable unbalance fix.

Dhinakaran Pandiyan b1e314462b drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.
If bios sets up an MST output and hardware state readout code sees this is
an SST configuration, when disabling the encoder we end up calling
->post_disable_dp() hook instead of the MST version. Consequently, we write
to the DP_SET_POWER dpcd to set it D3 state. Further along when we try
enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up
the MST hub. This results in continuous link training failures which keep
the system busy delaying boot. We could identify bios MST boot discrepancy
and handle it accordingly but a simple way to solve this is to write to the
DP_SET_POWER dpcd for MST too.

drm/sun4i: backend: Support YUV planes
Now that we have the guarantee that we will have only a single YUV plane,
actually support them. The way it works is not really straightforward,
since we first need to enable the YUV mode in the plane that we want to
setup, and then we have a few registers to setup the YUV buffer and
parameters.

We also need to setup the color correction to actually have something

drm/sun4i: Add support for A80 TCONs
The Allwinner A80 SoC has 2 documented TCONs. The display pipeline
diagram from the user manual shows a third TCON, but it's missing
an interrupt line, and its registers are not explained either.
It's also not used in Allwinner's vendor BSP.

The first TCON only has channel 0, for LCD panel output. The TCON
hardware setup is peculiar in that the eDP reset must also be
deasserted to allow access to the TCON. How the eDP module is wired
in the SoC itself is never explained.

The second TCON only has channel 1, and its output is connected to
the HDMI encoder block.

This patch adds a "needs_edp_reset" field to the tcon quirks structure,
and adds quirks and compatible strings for the 2 documented TCONs.

Joe Perches db87086492 drm: Reduce object size of DRM_DEV_<LEVEL> uses
These macros are similar to the DRM_<LEVEL> with the addition
of a struct device * to the arguments.

Convert the single drm_dev_printk function into 2 separate functions.
drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg
for conditional masked use.

Remove the __func__ argument and use __builtin_return_address(0) to be
similar to the DRM_<LEVEL> macros uses.

Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments
and use a consistent style.

These macros are rarely used in the generic gpu/drm code so the code
size does not change much for a defconfig, but when more drivers are
enabled, there is ~4k savings.

Many of these macros have no existing use at all.

Rob Clark f9cb8d8d83 drm/msm/mdp5: rework CTL START signal handling
For DSI cmd-mode and writeback, we need to write the CTL's START
register to kick things off, but we only want to do that once both
the encoder and the crtc have a chance to write their corresponding
flush bits.  The difficulty is that when there is a full modeset
(ie. encoder state has changed) we want to defer the start until
encoder->enable().  But if only plane's have changed, we want to do
this from crtc->commit().

The start_mask was a previous attempt to handle this, but it didn't
really do the right thing since atomic conversion.

Instead track in the crtc state that the start should be deferred,
set to try from encoder's (or in future writeback's) atomic_check().
This way the state is part of the atomic state, and rollback can
work properly if an atomic test fails.

Bjorn Andersson 79d57bf6fa drm/msm: Trigger fence completion from GPU
Interrupt commands causes the CP to trigger an interrupt as the command
is processed, regardless of the GPU being done processing previous
commands. This is seen by the interrupt being delivered before the
fence is written on 8974 and is likely the cause of the additional
CP_WAIT_FOR_IDLE workaround found for a306, which would cause the CP to
wait for the GPU to go idle before triggering the interrupt.

Instead we can set the (undocumented) BIT(31) of the CACHE_FLUSH_TS
which will cause a special CACHE_FLUSH_TS interrupt to be triggered from
the GPU as the write event is processed.

Add CACHE_FLUSH_TS to the IRQ masks of A3xx and A4xx and remove the
workaround for A306.

CTX_CONTEXT_CONTROL, we need to make sure all settings from guest would be set
when this context is on hw, this trys to force mask enable bits for all to

One regression found related to once inhibit bit is set, gpu engine are working
on inhibit state until MI_LOAD_REG_IMM command or context image clear inhibit
bit with mask bit set to 1, and val bit set to 0. In gvt-g currently workload
has the highest priority, so gvt-g workload could trigger preempt context
easily, preempt context set inhibit bit, then gvt-g workload is scheduled in,
but gvt-g workload shadow context image usually doesn't set inhibit mask bit,
so gpu is still in inhibit state when gvt workload is running. This caused gpu
hang.

Gustavo A. R. Silva 0126b23c55 drm/vc4_validate: Remove VLA usage
In preparation to enabling -Wvla, remove VLA. In this particular
case use macro ARRAY_SIZE so the length of array _bo_ can be
computed at preprocessing time.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
or a security flaw. Also, in general, as code evolves it is easy to
lose track of how big a VLA can get. Thus, we can end up having runtime
failures that are hard to debug.

Also, fixed as part of the directive to remove all VLAs from
the kernel: https://lkml.org/lkml/2018/3/7/621

Do the refresh rate calculation with a single division. This gives
us slightly more accurate results, especially for interlaced since
we don't just double the final truncated result.

We do lose one bit compared to the old way, so with an interlaced

Tvrtko Ursulin 22de4e7a53 drm/i915/pmu: Work around compiler warnings on some kernel configs
Arnd Bergman reports:
"""
The conditional spinlock confuses gcc into thinking the 'flags' value
might contain uninitialized data:

drivers/gpu/drm/i915/i915_pmu.c: In function '__i915_pmu_event_read':
arch/x86/include/asm/paravirt_types.h:573:3: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]

The code is correct, but it's easy to see how the compiler gets confused
here. This avoids the problem by pulling the lock outside of the function
into its only caller.
"""

On deeper look it seems this is caused by paravirt spinlocks
implementation when CONFIG_PARAVIRT_DEBUG is set, which by being
complicated, manages to convince gcc locked parameter can be changed
externally (impossible).

Work around it by removing the conditional locking parameters altogether.
(It was never the most elegant code anyway.)

Slight penalty we now pay is an additional irqsave spin lock/unlock cycle
on the event enable path. But since enable is not a fast path, that is
preferrable to the alternative solution which was doing MMIO under irqsave
spinlock.

tasklet_kill() will spin waiting for the current tasklet to be executed.
However, if tasklet_disable() has been called, then the tasklet is never
executed but permanently put back onto the runlist until
tasklet_enable() is called. Ergo, we cannot use tasklet_kill() inside a
disable/enable pair. This is the case when we call set-wedge from inside
i915_reset(), and another request was submitted to us concurrent to the

Chris Zhong 0a00ac97d2 drm/rockchip: cdn-dp: remove the DP phy switch
There are 2 Type-c PHYs in RK3399, but only one DP controller. Hence
only one PHY can connect to DP controller at one time, the other should
be disconnected. The GRF_SOC_CON26 register has a switch bit to do it,
set this bit means enable PHY 1, clear this bit means enable PHY 0.

If the board has 2 Type-C ports, the DP driver get the phy id from
devm_of_phy_get_by_index, and then control this switch according to
this id. But some others board only has one Type-C port, it may be PHY 0
or PHY 1. The dts node id can not tell us the correct PHY id. Hence move
this switch to PHY driver, the PHY driver can distinguish between PHY 0
and PHY 1, and then write the correct register bit.
