4 years agodrm/scheduler: fix inconsistent locking of job_list_lock
Lucas Stach [Mon, 20 Jan 2020 10:51:19 +0000 (11:51 +0100)]
drm/scheduler: fix inconsistent locking of job_list_lock

2130e7c1c09a (drm/scheduler: Add drm_sched_suspend/resume_timeout()) made
the job_list_lock IRQ safe in as the suspend/resume calls were expected to
be called from IRQ context. This usage never materialized in upstream.
Instead amdgpu started locking the job_list_lock in an IRQ unsafe way in
amdgpu_ib_preempt_mark_partial_job() and amdgpu_ib_preempt_job_recovery(),
which leads to potential deadlock if one would actually start to call the
drm_sched_suspend/resume_timeout functions from IRQ context.

As no current user needs the locking to be IRQ safe, the local IRQ
disable/enable is pure overhead. Fix the inconsistent locking by changing
all uses of job_list_lock to use the IRQ unsafe locking primitives.

4 years agodrm/amd/display: Add link_rate quirk for Apple 15" MBP 2017
Mario Kleiner [Fri, 28 Feb 2020 21:36:07 +0000 (22:36 +0100)]
drm/amd/display: Add link_rate quirk for Apple 15" MBP 2017

This fixes a problem found on the MacBookPro 2017 Retina panel:

The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec aka LINK_RATE_RBR2
aka 0xc), but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.

This restricts the panel to 8 bpc, not providing the full
color depth of the panel on Linux <= 5.5. Additionally, commit
'8eec062fef6e ("drm/amd/display: Default max bpc to 16 for eDP")'
introduced into Linux 5.6-rc1 will unclamp panel depth to
its full 10 bpc, thereby requiring a eDP bandwidth for all
modes that exceeds the bandwidth available and causes all modes
to fail validation -> No modes for the laptop panel -> failure
to set any mode -> Panel goes dark.

This patch adds a quirk specific to the MBP 2017 15" Retina
panel to override reported max link rate to the correct maximum
of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display
precision.

Please apply for Linux 5.6+ to avoid regressing Apple MBP panel
support.

ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*,
but they are interweavedly used in kernel driver, resulting in bad
readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is not

[Why]
System isn't able to enter S0i3 due to not send display count 0 to smu.
When dpms off, clk changed flag is cleared alreay, and it is checked

values are checked during update to determine whether to perform it, no
need to check it again outside the function.
