2021-07-20drm/amdkfd: fix sysfs kobj leakPhilip Yang2-8/+7
[ Upstream commit dcdb4d904b4bd3078fe8d4d24b1658560d6078ef ] 3 cases of kobj leak, which causes memory leak: kobj_type must have release() method to free memory from release callback. Don't need NULL default_attrs to init kobj. sysfs files created under kobj_status should be removed with kobj_status as parent kobject. Remove queue sysfs files when releasing queue from process MMU notifier release callback.

2021-07-20drm/dp_mst: Avoid to mess up payload table by ports in stale topologyWayne Lin1-0/+29
commit 3769e4c0af5b82c8ea21d037013cb9564dfaa51f upstream. [Why] After unplug/hotplug hub from the system, userspace might start to clear stale payloads gradually. If we call drm_dp_mst_deallocate_vcpi() to release stale VCPI of those ports which are not relating to current topology, we have chane to wrongly clear active payload table entry for current topology. E.g. We have allocated VCPI 1 in current payload table and we call drm_dp_mst_deallocate_vcpi() to clean VCPI 1 in stale topology. In drm_dp_mst_deallocate_vcpi(), it will call drm_dp_mst_put_payload_id() tp put VCPI 1 and which means ID 1 is available again. Thereafter, if we want to allocate a new payload stream, it will find ID 1 is available by drm_dp_mst_assign_payload_id(). However, ID 1 is being used [How] Check target sink is relating to current topology or not before doing any payload table update. Searching upward to find the target sink's relevant root branch device. If the found root branch device is not the same root of current topology, don't update payload table. Changes since v1: * Change debug macro to use drm_dbg_kms() instead * Amend the commit message to add Cc tag.

2021-07-20drm/dp_mst: Do not set proposed vcpi directlyWayne Lin1-26/+10
commit 35d3e8cb35e75450f87f87e3d314e2d418b6954b upstream. [Why] When we receive CSN message to notify one port is disconnected, we will implicitly set its corresponding num_slots to 0. Later on, we will eventually call drm_dp_update_payload_part1() to arrange down streams. In drm_dp_update_payload_part1(), we iterate over all proposed_vcpis[] to do the update. Not specific to a target sink only. For example, if we light up 2 monitors, Monitor_A and Monitor_B, and then we unplug Monitor_B. Later on, when we call drm_dp_update_payload_part1() to try to update payload for Monitor_A, we'll also implicitly clean payload for Monitor_B at the same time. And finally, when we try to call drm_dp_update_payload_part1() to clean payload for Monitor_B, we will do nothing at this time since payload for Monitor_B has been cleaned up previously. For StarTech 1to3 DP hub, it seems like if we didn't update DPCD payload ID table then polling for "ACT Handled"(BIT_1 of DPCD 002C0h) will fail and this polling will last for 3 seconds. Therefore, guess the best way is we don't set the proposed_vcpi[] diretly. Let user of these herlper functions to set the proposed_vcpi directly. [How] 1. Revert commit 7617e9621bf2 ("drm/dp_mst: clear time slots for ports invalid") 2. Tackle the issue in previous commit by skipping those trasient proposed VCPIs. These stale VCPIs shoulde be explicitly cleared by user later on.

2021-07-20drm/i915/gt: Fix -EDEADLK handling regressionVille Syrjälä1-1/+1
commit 2feeb52859fc1ab94cd35b61ada3a6ac4ff24243 upstream. The conversion to ww mutexes failed to address the fence code which already returns -EDEADLK when we run out of fences. Ww mutexes on the other hand treat -EDEADLK as an internal errno value indicating a need to restart the operation due to a deadlock. So now when the fence code returns -EDEADLK the higher level code erroneously restarts everything instead of returning the error to userspace as is expected. To remedy this let's switch the fence code to use a different errno value for this. -ENOBUFS seems like a semi-reasonable unique choice. Apart from igt the only user of this I could find is sna, and even there all we do is dump the current fence registers from debugfs into the X server log. So no user visible functionality is affected. If we really cared about preserving this we could of course convert back to -EDEADLK higher up, but doesn't seem like that's worth the hassle here. Not quite sure which commit specifically broke this, but I'll just attribute it to the general gem ww mutex work.

2021-07-20drm/i915/gtt: drop the page table optimisationMatthew Auld1-4/+1
commit 0abb33bfca0fb74df76aac03e90ce685016ef7be upstream. We skip filling out the pt with scratch entries if the va range covers the entire pt, since we later have to fill it with the PTEs for the object pages anyway. However this might leave open a small window where the PTEs don't point to anything valid for the HW to consume. When for example using 2M GTT pages this fill_px() showed up as being quite significant in perf measurements, and ends up being completely wasted since we ignore the pt and just use the pde directly. Anyway, currently we have our PTE construction split between alloc and insert, which is probably slightly iffy nowadays, since the alloc doesn't actually allocate anything anymore, instead it just sets up the page directories and points the PTEs at the scratch page. Later when we do the insert step we re-program the PTEs again. Better might be to squash the alloc and insert into a single step, then bringing back this optimisation(along with some others) should be possible.

commit b354498bbe65c917d521b3b56317ddc9ab217425 upstream. commit cf6d100dd238 ("drm/rockchip: dsi: add dual mipi support") added this devcnt field and call to component_del(). However, these both appear to be erroneous changes left over from an earlier version of the patch. In the version merged, nothing ever modifies devcnt, meaning component_del() runs unconditionally and in addition to the component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second call fails to delete anything and produces a warning in dmesg. If we look at the previous version of the patch[1], however, we see that it had logic to calculate devcnt and call component_add() in certain situations. This was removed in v6, and the fact that the deletion code was not appears to have been an oversight.

Since we fixed the hooks to disable the encoder at boot, we now have an unbalanced clk_disable call at boot since we never enabled them in the first place. Let's mimic the state of the hardware and enable the clocks at boot if the controller is enabled to get the use-count right.

2021-07-19drm/vc4: crtc: Skip the TXPMaxime Ripard1-0/+3
commit 47a50743031ad4138050ae6d266ddd3dfe845ead upstream. The vc4_set_crtc_possible_masks is meant to run over all the encoders and then set their possible_crtcs mask to their associated pixelvalve. However, since the commit 39fcb2808376 ("drm/vc4: txp: Turn the TXP into a CRTC of its own"), the TXP has been turned to a CRTC and encoder of its own, and while it does indeed register an encoder, it no longer has an associated pixelvalve. The code will thus run over the TXP encoder and set a bogus possible_crtcs mask, overriding the one set in the TXP bind function. In order to fix this, let's skip any virtual encoder.

2021-07-19drm/radeon: Call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64Tiezhu Yang1-4/+4
commit c1bfd74bfef77bcefc88d12eaf8996c0dfd51331 upstream. On the Loongson64 platform used with Radeon GPU, shutdown or reboot failed when console=tty is in the boot cmdline. radeon_suspend_kms() puts the hw in the suspend state, especially set fb state as FBINFO_STATE_SUSPENDED: if (fbcon) { console_lock(); radeon_fbdev_set_suspend(rdev, 1); console_unlock(); } Then avoid to do any more fb operations in the related functions: if (p->state != FBINFO_STATE_RUNNING) return; So call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64 to fix this issue, it looks like some kind of workaround like powerpc.
