2020-03-13drm/i915/tgl: Remove require_force_probe protectionJosé Roberto de Souza1-1/+0
We have a few TGL machines in our CI and it is mostly green with failures in tests that will not impact future Linux installations. Also there is no warnings, errors, flickering or any visual defects while doing ordinary tasks like browsing and editing documents in a dual monitor setup. As a reminder i915.require_force_probe was created to protect future Linux installation's iso images that might contain a kernel from the enabling time of the new platform. Without this protection most of linux installation was recommending nomodeset option during installation that was getting stick there after installation.

2020-03-13drm/i915: Add Wa_1604278689:icl,ehlMatt Roper2-0/+7
The bspec description for this workaround tells us to program 0xFFFF_FFFF into both FBC_RT_BASE_ADDR_REGISTER_* registers, but we've previously found that this leads to failures in CI. Our suspicion is that the failures are caused by this valid turning on the "address valid bit" even though we're intentionally supplying an invalid address. Experimentation has shown that setting all bits _except_ for the RT_VALID bit seems to avoid these failures. v2: - Mask off the RT_VALID bit. Experimentation with CI trybot indicates that this is necessary to avoid reset failures on BCS. v3: - Program RT_BASE before RT_BASE_UPPER so that the valid bit is turned off by the first write.

2020-03-13drm/scheduler: fix inconsistent locking of job_list_lockLucas Stach1-26/+17
1db8c142b6c5 (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.

2020-03-13drm/amd/display: Add link_rate quirk for Apple 15" MBP 2017Mario Kleiner1-0/+11
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 '4a8ca46bae8a ("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. Signed-off-by: Mario Kleiner <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2020-03-12drm/vmwgfx: Drop preempt_disable() in vmw_fifo_ping_host()Sebastian Andrzej Siewior1-2/+0
vmw_fifo_ping_host() disables preemption around a test and a register write via vmw_write(). The write function acquires a spinlock_t typed lock which is not allowed in a preempt_disable()ed section on PREEMPT_RT. This has been reported in the bugzilla. It has been explained by Thomas Hellstrom that this preempt_disable()ed section is not required for correctness. Remove the preempt_disable() section.
