17 months agodrm/fb-helper: Remove drm_fb_helper_unprepare() from drm_fb_helper_fini()
Thomas Zimmermann [Thu, 16 Feb 2023 14:06:20 +0000 (15:06 +0100)]
drm/fb-helper: Remove drm_fb_helper_unprepare() from drm_fb_helper_fini()

Move drm_fb_helper_unprepare() from drm_fb_helper_fini() into the
calling fbdev implementation. Avoids a possible stale mutex with
generic fbdev code.

As indicated by its name, drm_fb_helper_prepare() prepares struct
drm_fb_helper before setting up the fbdev support with a call to
drm_fb_helper_init(). In legacy fbdev emulation, this happens next
to each other. If successful, drm_fb_helper_fini() later tear down
the fbdev device and also unprepare via drm_fb_helper_unprepare().

Generic fbdev emulation prepares struct drm_fb_helper immediately
after allocating the instance. It only calls drm_fb_helper_init()
as part of processing a hotplug event. If the hotplug-handling fails,
it runs drm_fb_helper_fini(). This unprepares the fb-helper instance
and the next hotplug event runs on stale data.

Solve this by moving drm_fb_helper_unprepare() from drm_fb_helper_fini()
into the fbdev implementations. Call it right before freeing the
fb-helper instance.

17 months agodrm/amd/display: disable SubVP + DRR to prevent underflow

drm/amd/display: disable SubVP + DRR to prevent underflow

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.

Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.

If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:

amdgpu.dcfeaturemask=0x200

drm/i915: Fix GEN8_MISCCPCTL

Register 0x9424 is not replicated on any platform, so it shouldn't be
declared with REG_MCR(). Declaring it with _MMIO() is basically
duplicate of the GEN7 version, so just remove the GEN8 and change all
the callers to use the right functions.

Old versions of the gen8 bspec page used to contain a table with MCR
registers, apparently implying 0x9400 - 0x94ff registers were
replicated. However that table went away and there is no information
related to the ranges for gen8 anymore. Moreover the current behavior of
the driver wouldn't do anything special for 0x9424 since there is no
equivalent table in intel_gt_mcr.c: the driver would just fallback to
intel_uncore_{read,write}(). Therefore, do not care about the possible
special case for gen8 and just use the register as non-MCR for all the
platforms.

One place doing read + write is also converted to intel_uncore_rmw().

v2: Reword commit message adding the justification wrt gen8

The workarounds/tuning settings should still be applied properly on PVC

CONFIG_DRM_I915_DEBUG_GEM builds could potentitally give false positive

drm/amd/display: Add support for multiple overlay planes

[Why]
We only allowed 1 overlay plane. But now some ASICS can support multiple
overlay planes.

[How]
Use max_slave_planes as the number of overlays we can support.

Also since we cannot draw cursor over a video plane, we need to make
sure that we reject commits where the topmost plane is a video plane
(overlay only).

17 months agodrm/amd/display: move public dc link function implementation to dc_link_exports
Wenjing Liu [Wed, 1 Feb 2023 21:07:35 +0000 (16:07 -0500)]
drm/amd/display: move public dc link function implementation to dc_link_exports

[why]
Link is a subcomponent in dc. DM should be aware of dc link structure
as one of the abstracted objects maintained by dc. However it should
have no idea of the existence of a link component in dc dedicated to
maintain the states of dc link structure. As such we are moving link interfaces
out of dc_link.h and directly added to dc.h. We are grandually fading out
the explicit inclusion of dc_link header and eventually delete it.

On dc side, since link is a subcomponent behind dc interfaces, it is not
a good idea to implement dc interfaces in each individual subcomponent
of link which is already a subcomponent of dc. So we are decoupling it
by implementing a dc_link_exports in dc. This file will be a thin
translation layer that breaks the dependency so link is able to make
interface changes without breaking DM.

[Why]
Regression of commit 72fef4980ddf ("drm/amdgpu: Remove writing GRBM_GFX_CNTL in RLCG interface under SRIOV") on GFX9.
According to GFX9 VF using different method to access GC registers including MMIO(direct) and RLCG(indirect),
removing GRBM_GFX_* writing would make PIPE/ME/VM/QUEUE selection chaos leading to some OCL benchmark failure.

For example,
using RLCG interface to program GRBM_GFX_CNTL/INDEX for selecting MEC(actually the value is only in scratch2/3),
then using MMIO directly program a MEC register in VF driver.
The register programming are invalid due to GC switched to incorrect ME.

[How]
With checking RLCG accessing flag, keep writing GRBM_GFX_* as a legacy way.
But it is still skipped on GFX10+ to avoid violation occurrence.

17 months agodrm/i915/dp_mst: Fix payload removal during output disabling
Imre Deak [Mon, 6 Feb 2023 11:48:56 +0000 (13:48 +0200)]
drm/i915/dp_mst: Fix payload removal during output disabling

Use the correct old/new topology and payload states in
intel_mst_disable_dp(). So far drm_atomic_get_mst_topology_state() it
used returned either the old state, in case the state was added already
earlier during the atomic check phase or otherwise the new state (but
the latter could fail, which can't be handled in the enable/disable
hooks). After the first patch in the patchset, the state should always
get added already during the check phase, so here we can get the
old/new states without a failure.

drm_dp_remove_payload() should use time_slots from the old payload state
and vc_start_slot in the new one. It should update the new payload
states to reflect the sink's current payload table after the payload is
removed. Pass the new topology state and the old and new payload states
accordingly.

This also fixes a problem where the payload allocations for multiple MST
streams on the same link got inconsistent after a few commits, as
during payload removal the old instead of the new payload state got
updated, so the subsequent enabling sequence and commits used a stale
payload state.

v2: Constify the old payload state pointer. (Ville)

drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()

Atm, drm_dp_remove_payload() uses the same payload state to both get the
vc_start_slot required for the payload removal DPCD message and to
deduct time_slots from vc_start_slot of all payloads after the one being
removed.

The above isn't always correct, as vc_start_slot must be the up-to-date
version contained in the new payload state, but time_slots must be the
one used when the payload was previously added, contained in the old
payload state. The new payload's time_slots can change vs. the old one
if the current atomic commit changes the corresponding mode.

This patch let's drivers pass the old and new payload states to
drm_dp_remove_payload(), but keeps these the same for now in all drivers
not to change the behavior. A follow-up i915 patch will pass in that

17 months agodrm/amdgpu/fence: Fix oops due to non-matching drm_sched init/fini
Guilherme G. Piccoli [Thu, 2 Feb 2023 13:48:56 +0000 (10:48 -0300)]
drm/amdgpu/fence: Fix oops due to non-matching drm_sched init/fini

Currently amdgpu calls drm_sched_fini() from the fence driver sw fini
routine - such function is expected to be called only after the
respective init function - drm_sched_init() - was executed successfully.

Happens that we faced a driver probe failure in the Steam Deck
recently, and the function drm_sched_fini() was called even without
its counter-part had been previously called, causing the following oops:

amdgpu: probe of 0000:04:00.0 failed with error -110
BUG: kernel NULL pointer dereference, address: 0000000000000090

 amdgpu_driver_release_kms+0x16/0x30 [amdgpu]
 devm_drm_dev_init_release+0x49/0x70
 [...]

To prevent that, check if the drm_sched was properly initialized for a
given ring before calling its fini counter-part.

Notice ideally we'd use sched.ready for that; such field is set as the latest
thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such
field - in the above oops for example, it was a GFX ring causing the crash, and
the sched.ready field was set to true in the ring init routine, regardless of
the state of the DRM scheduler. Hence, we ended-up using sched.ops as per
Christian's suggestion [0], and also removed the no_scheduler check [1].

drm/amdgpu: Use the TGID for trace_amdgpu_vm_update_ptes

The pid field corresponds to the result of gettid() in userspace.
However, userspace cannot reliably attribute PTE events to processes
with just the thread id. This patch allows userspace to easily
attribute PTE update events to specific processes by comparing this
field with the result of getpid().

For attributing events to specific threads, the thread id is also
contained in the common fields of each trace event.
