Jordan Crouse 568692102b drm/msm/gpu: Add per-submission statistics
Add infrastructure to track statistics for GPU submissions
by sampling certain perfcounters before and after a submission.

To store the statistics, the per-ring memptrs region is
expanded to include room for up to 64 entries - this should
cover a reasonable amount of inflight submissions without
worrying about losing data. The target specific code inserts
PM4 commands to sample the counters before and after
submission and store them in the data region. The CPU can
access the data after the submission retires to make sense
of the statistics and communicate them to the user.

Jordan Crouse 93f7abf19d drm/msm: Gracefully handle failure in _msm_gem_kernel_new
If any of the function calls in _msm_gem_kernel_new fail we need
to make sure to dereference the GEM object with the appropriate
function for the current locking state.

Jordan Crouse 546ec7b471 drm/msm/gpu: Allocate the correct size for the GPU memptrs
Allocate the correct buffer size for the GPU memptrs. The incorrect
size hasn't affected us thus far since the incorrect size was larger
than the intended size and we're still stuck on page sized
granularity anyway but technically correct is the best kind of
correct.

Bruce Wang 9a5e3fce4b drm/msm/dpu: Replace dpu_crtc_reset by atomic helper
Since we removed all suspend logic from the crtc code (see patch 3/4),
dpu_crtc_reset does the same things as drm_atomic_helper_crtc_reset, so let's
just replace it with a call to the atomic helper.

Bruce Wang 7a007a121d drm/msm/dpu: Remove suspend state tracking from crtc
Since drm core's modeset locks serialize atomic commits, we don't need to
track whether or not we're in a suspended state from inside the crtc for
dpu_crtc_enable/disable. This patch removes the suspend logic from the crtc and
removes the relevant tracing from dpu_trace. Since we removed all calls
to dpu_kms_is_suspend_state, we can remove that function and the
suspend_state field of dpu_kms as well.

v2: added patch to patchset
v3: reworded commit body and moved deletion of dpu_kms_is_suspend_state and
suspend_state to this patch

msm_pm_suspend/resume since we just deleted those functions (see patch
1). Also removes the drm_kms_helper_poll_disable/enable calls, since
the DRM_CONNECTOR_POLL_CONNECT flag is never set so periodic polling
doesn't happen anyways.

Brian Norris 63238173b2 Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"
This reverts commit 7f3ef5dedb.

It causes new warnings [1] on shutdown when running the Google Kevin or
Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is
different than what Marc and Heiko test.

We're looking at a different approach (e.g., [2]) to replace this, but
IMO the revert should be taken first, as it already propagated to
-stable.

[WHY] clarify dal input parameters to pplib interface, remove
un-used parameters. dal knows exactly which parameters needed
and their effects at pplib and smu sides.

current dal sequence for dcn1_update_clock to pplib:

1.smu10_display_clock_voltage_request for dcefclk
2.smu10_display_clock_voltage_request for fclk
3.phm_store_dal_configuration_data {
  set_min_deep_sleep_dcfclk
  set_active_display_count
  store_cc6_data --- this data never be referenced

new sequence will be:

1. set_display_count  --- need add new pplib interface
2. set_min_deep_sleep_dcfclk -- new pplib interface
3. set_hard_min_dcfclk_by_freq
4. set_hard_min_fclk_by_freq

after this code refactor, smu10_display_clock_voltage_request,
phm_store_dal_configuration_data will not be needed for rv.

Thierry Reding 180b46ecdc drm/tegra: sor: Reset the SOR if possible
If the SOR is already up and running when the kernel driver is probed,
setting a mode will typically fail. This can be seen for example on
Jetson TX2. Under certain circumstances the generic power domain code
will cause the SOR to be reset. However, if the power domain is never
powered off (this can happen if the HDA controller is enabled, which
is part of the same power domain as the SOR), then the SOR will end up
not getting reset and fail to properly set a mode.

To work around this, try to get the reset control and assert/deassert
it, irrespective of whether or not a generic power domain is attached
to the SOR. On platforms where the kernel implements generic power
domains (up to Tegra210) this will fail, because the power domain will
already have acquired an exclusive reference to the reset control. But
on recent platforms there the BPMP provides an ABI to control power
domains, it's possible to acquire the reset control from SOR and use
it to put the SOR into a known good state at probe time.

The proper solution for this is to make the SOR driver capable of
dealing with hardware that's already up and running (by first grace-
fully shutting it down, or perhaps by seamlessly transitioning to the
kernel driver and taking over the running display configuration). That
is fairly involved, though, so we'll go with this quickfix for now.

This patch adds two new functions to help client drivers suspend and
resume the scheduler job timeout. This can be useful in cases where the
hardware has preemption support enabled. Using this, it is possible to have
the timeout active only for the ring which is active on the ringbuffer.
This patch also makes the job_list_lock IRQ safe.

Tvrtko Ursulin 90098efacc drm/i915: Introduce per-engine workarounds
We stopped re-applying the GT workarounds after engine reset since commit
59b449d5c8 ("drm/i915: Split out functions for different kinds of
workarounds").

Issue with this is that some of the GT workarounds live in the MMIO space
which gets lost during engine resets. So far the registers in 0x2xxx and
0xbxxx address range have been identified to be affected.

This losing of applied workarounds has obvious negative effects and can
even lead to hard system hangs (see the linked Bugzilla).

Rather than just restoring this re-application, because we have also
observed that it is not safe to just re-write all GT workarounds after
engine resets (GPU might be live and weird hardware states can happen),
we introduce a new class of per-engine workarounds and move only the
affected GT workarounds over.

Using the framework introduced in the previous patch, we therefore after
engine reset, re-apply only the workarounds living in the affected MMIO
address ranges.

v2:
 * Move Wa_1406609255:icl to engine workarounds as well.
 * Rename API. (Chris Wilson)
 * Drop redundant IS_KABYLAKE. (Chris Wilson)
 * Re-order engine wa/ init so latest platforms are first. (Rodrigo Vivi)

Tvrtko Ursulin 009367791f drm/i915: Record GT workarounds in a list
To enable later verification of GT workaround state at various stages of
driver lifetime, we record the list of applicable ones per platforms to a
list, from which they are also applied.

The added data structure is a simple array of register, mask and value
items, which is allocated on demand as workarounds are added to the list.

This is a temporary implementation which later in the series gets fused
with the existing per context workaround list handling. It is separated at
this stage since the following patch fixes a bug which needs to be as easy
to backport as possible.

Also, since in the following patch we will be adding a new class of
workarounds (per engine) which can be applied from interrupt context, we
straight away make the provision for safe read-modify-write cycle.

v2:
 * Change dev_priv to i915 along the init path. (Chris Wilson)
 * API rename. (Chris Wilson)

v3:
 * Remove explicit list size tracking in favour of growing the allocation
   in power of two chunks. (Chris Wilson)

v4:
 Chris Wilson:
 * Change wa_list_finish to early return.
 * Copy workarounds using the compiler for static checking.
 * Do not bother zeroing unused entries.
 * Re-order struct i915_wa_list.

v5:
 * kmalloc_array.
 * Whitespace cleanup.

Lukasz Spintzyk d3b2176782 drm: Add a new plane property to send damage during plane update
FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.

The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.

This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.

Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.

v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.

Nicholas Kazlauskas 090afc1e40 drm/amd/display: Fix overflow/truncation from strncpy.
[Why]

New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.

[How]

Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.

The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.

This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

Chris Wilson 5179749925 drm/i915: Allocate a common scratch page
Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.

For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

Tvrtko Ursulin 4a15c75c42 drm/i915: Introduce per-engine workarounds
We stopped re-applying the GT workarounds after engine reset since commit
59b449d5c8 ("drm/i915: Split out functions for different kinds of
workarounds").

Issue with this is that some of the GT workarounds live in the MMIO space
which gets lost during engine resets. So far the registers in 0x2xxx and
0xbxxx address range have been identified to be affected.

This losing of applied workarounds has obvious negative effects and can
even lead to hard system hangs (see the linked Bugzilla).

Rather than just restoring this re-application, because we have also
observed that it is not safe to just re-write all GT workarounds after
engine resets (GPU might be live and weird hardware states can happen),
we introduce a new class of per-engine workarounds and move only the
affected GT workarounds over.

Using the framework introduced in the previous patch, we therefore after
engine reset, re-apply only the workarounds living in the affected MMIO
address ranges.

v2:
 * Move Wa_1406609255:icl to engine workarounds as well.
 * Rename API. (Chris Wilson)
 * Drop redundant IS_KABYLAKE. (Chris Wilson)
 * Re-order engine wa/ init so latest platforms are first. (Rodrigo Vivi)

Tvrtko Ursulin 25d140faaa drm/i915: Record GT workarounds in a list
To enable later verification of GT workaround state at various stages of
driver lifetime, we record the list of applicable ones per platforms to a
list, from which they are also applied.

The added data structure is a simple array of register, mask and value
items, which is allocated on demand as workarounds are added to the list.

This is a temporary implementation which later in the series gets fused
with the existing per context workaround list handling. It is separated at
this stage since the following patch fixes a bug which needs to be as easy
to backport as possible.

Also, since in the following patch we will be adding a new class of
workarounds (per engine) which can be applied from interrupt context, we
straight away make the provision for safe read-modify-write cycle.

 * Do not bother zeroing unused entries.

Madhav Chauhan 2eae5d6bfa drm/i915/icl: Get pipe timings for DSI
Transcoder timings for Gen11 DSI encoder
is available at pipe level unlike in older platform
where port specific registers need to be accessed.

v2 by Jani:
 - get timings for (!dsi || icl) instead of (dsi && icl).

Madhav Chauhan 2ca711caec drm/i915/icl: Consider DSI for getting transcoder state
For Gen11 DSI, we use similar registers like for eDP
to find if DSI encoder is connected or not to a pipe.
This patch refactors existing hsw_get_transcoder_state()
to handle this.

v2 by Jani:
 - Add WARN_ON(dsi && edp) (Ville)
