2022-11-17drm/i915/edp: wait power off delay at driver remove to optimize probeJani Nikula2-1/+13
Panel power off delay is the time the panel power needs to remain off after being switched off, before it can be switched on again. For the purpose of respecting panel power off delay at driver probe, assuming the panel was last switched off at driver probe is overly pessimistic. If the panel was never on, we'd end up waiting for no reason. We don't know what has happened before kernel boot, but we can make some assumptions: - The panel may have been switched off right before kernel boot by some pre-os environment. - After kernel boot, the panel may only be switched off by i915. - At i915 driver probe, only a previously loaded and removed i915 may have switched the panel power off. With these assumptions, we can initialize the last power off time to kernel boot time, if we also ensure i915 driver remove waits for the panel power off delay after switching panel power off. This shaves off the time it takes from kernel boot to i915 probe from the first panel enable, if (and only if) the panel was not already enabled at boot. The encoder destroy hook is pretty much the last place where we can wait, right after we've ensured the panel power has been switched off, and before the whole encoder is destroyed.

Now that we've fixed the issue with using the incorrect topology manager, we're actually grabbing the topology manager's lock - and consequently deadlocking. Luckily for us though, there's actually nothing in AMD's DSC state computation code that really should need this lock. The one exception is the mutex_lock() in dm_dp_mst_is_port_support_mode(), however we grab no locks beneath &mgr->lock there so that should be fine to leave be.

2022-11-17drm/amdgpu/dm/mst: Use the correct topology mgr pointer in amdgpu_dm_connectorLyude Paul1-19/+18
This bug hurt me. Basically, it appears that we've been grabbing the entirely wrong mutex in the MST DSC computation code for amdgpu! While we've been grabbing: amdgpu_dm_connector->mst_mgr That's zero-initialized memory, because the only connectors we'll ever actually be doing DSC computations for are MST ports. Which have mst_mgr zero-initialized, and instead have the correct topology mgr pointer located at: amdgpu_dm_connector->mst_port->mgr; I'm a bit impressed that until now, this code has managed not to crash anyone's systems! It does seem to cause a warning in LOCKDEP though: [ 66.637670] DEBUG_LOCKS_WARN_ON(lock->magic != lock) This was causing the problems that appeared to have been introduced by: commit 4d07b0bc4034 ("drm/display/dp_mst: Move all payload info into the atomic state") This wasn't actually where they came from though. Presumably, before the only thing we were doing with the topology mgr pointer was attempting to grab mst_mgr->lock. Since the above commit however, we grab much more information from mst_mgr including the atomic MST state and respective modesetting locks. This patch also implies that up until now, it's quite likely we could be susceptible to race conditions when going through the MST topology state for DSC computations since we technically will not have grabbed any lock when going through it. So, let's fix this by adjusting all the respective code paths to look at the right pointer and skip things that aren't actual MST connectors from a topology.

It appears that amdgpu makes the mistake of completely ignoring the return values from the DP MST helpers, and instead just returns a simple true/false. In this case, it seems to have come back to bite us because as a result of simply returning false from compute_mst_dsc_configs_for_state(), amdgpu had no way of telling when a deadlock happened from these helpers.

2022-11-16drm/edid/firmware: stop using a throwaway platform deviceJani Nikula1-12/+1
We've used a temporary platform device for firmware EDID loading since it was introduced in commit da0df92b5731 ("drm: allow loading an EDID as firmware to override broken monitor"), but there's no explanation why. Using a temporary device does not play well with CONFIG_FW_CACHE=y, which caches firmware images (e.g. on suspend) so that drivers can request firmware when the system is not ready for it, and return the images from the cache (e.g. during resume). This works automatically for regular devices, but obviously not for a temporarily created device. Stop using the throwaway platform device, and use the drm device instead. Note that this may still be problematic for cases where the display was plugged in during suspend, and the firmware wasn't loaded and therefore not cached before suspend.

2022-11-16fbdev: Add support for the nomodeset kernel parameterThomas Zimmermann47-2/+246
Support the kernel's nomodeset parameter for all PCI-based fbdev drivers that use aperture helpers to remove other, hardware-agnostic graphics drivers. The parameter is a simple way of using the firmware-provided scanout buffer if the hardware's native driver is broken. The same effect could be achieved with per-driver options, but the importance of the graphics output for many users makes a single, unified approach worthwhile. With nomodeset specified, the fbdev driver module will not load. This unifies behavior with similar DRM drivers. In DRM helpers, modules first check the nomodeset parameter before registering the PCI driver. As fbdev has no such module helpers, we have to modify each driver individually. The name 'nomodeset' is slightly misleading, but has been chosen for historical reasons. Several drivers implemented it before it became a general option for DRM. So keeping the existing name was preferred over introducing a new one. v2: * print a warning if a driver does not init (Helge) * wrap video_firmware_drivers_only() in helper Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Schedule the deferred-I/O worker instead of the damage worker after writing to the fbdev framebuffer. The deferred-I/O worker then performs the dirty-fb update. The fbdev emulation will initialize deferred I/O for all drivers that require damage updates. It is therefore a valid assumption that the deferred-I/O worker is present. It would be possible to perform the damage handling directly from within the write operation. But doing this could increase the overhead of the write or interfere with a concurrently scheduled deferred-I/O worker. Instead, scheduling the deferred-I/O worker with its regular delay of 50 ms removes load off the write operation and allows the deferred-I/O worker to handle multiple write operations that arrived during the delay time window. v3: * remove unused variable (lkp) v2: * keep drm_fb_helper_damage() (Daniel) * use fb_deferred_io_schedule_flush() (Daniel) * clarify comments (Daniel) Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

drm_mode_config_init() simply calls drmm_mode_config_init(), hence cleanup is automatically handled through registering drm_mode_config_cleanup() with drmm_add_action_or_reset(). While at it, get rid of the deprecated drm_mode_config_init() and replace it with drmm_mode_config_init() directly.

2022-11-16drm/arm/malidp: replace drm->dev_private with drm_to_malidp()Danilo Krummrich6-27/+25
Using drm_device->dev_private is deprecated. Since we've switched to devm_drm_dev_alloc(), struct drm_device is now embedded in struct malidp_drm, hence we can use container_of() to get the struct drm_device instance instead.

Use drm managed resources to allocate driver structures and get rid of the deprecated drm_dev_alloc() call and replace it with devm_drm_dev_alloc(). This also serves as preparation to get rid of drm_device->dev_private and to fix use-after-free issues on driver unload.

2022-11-16drm/i915/ttm: never purge busy objectsMatthew Auld1-0/+4
In i915_gem_madvise_ioctl() we immediately purge the object is not currently used, like when the mm.pages are NULL. With shmem the pages might still be hanging around or are perhaps swapped out. Similarly with ttm we might still have the pages hanging around on the ttm resource, like with lmem or shmem, but here we need to be extra careful since async unbinds are possible as well as in-progress kernel moves. In i915_ttm_purge() we expect the pipeline-gutting to nuke the ttm resource for us, however if it's busy the memory is only moved to a ghost object, which then leads to broken behaviour when for example clearing the i915_tt->filp, since the actual ttm_tt is still alive and populated, even though it's been moved to the ghost object. When we later destroy the ghost object we hit the following, since the filp is now NULL: [ +0.006982] #PF: supervisor read access in kernel mode [ +0.005149] #PF: error_code(0x0000) - not-present page [ +0.005147] PGD 11631d067 P4D 11631d067 PUD 115972067 PMD 0 [ +0.005676] Oops: 0000 [#1] PREEMPT SMP NOPTI [ +0.012962] Workqueue: events ttm_device_delayed_workqueue [ttm] [ +0.006022] RIP: 0010:i915_ttm_tt_unpopulate+0x3a/0x70 [i915] [ +0.005879] Code: 89 fb 48 85 f6 74 11 8b 55 4c 48 8b 7d 30 45 31 c0 31 c9 e8 18 6a e5 e0 80 7d 60 00 74 20 48 8b 45 68 8b 55 08 4c 89 e7 5b 5d <48> 8b 40 20 83 e2 01 41 5c 89 d1 48 8b 70 30 e9 42 b2 ff ff 4c 89 [ +0.018782] RSP: 0000:ffffc9000bf6fd70 EFLAGS: 00010202 [ +0.005244] RAX: 0000000000000000 RBX: ffff8883e12ae380 RCX: 0000000000000000 [ +0.007150] RDX: 000000008000000e RSI: ffffffff823559b4 RDI: ffff8883e12ae3c0 [ +0.007142] RBP: ffff888103b65d48 R08: 0000000000000001 R09: 0000000000000001 [ +0.007144] R10: 0000000000000001 R11: ffff88829c2c8040 R12: ffff8883e12ae3c0 [ +0.007148] R13: 0000000000000001 R14: ffff888115184140 R15: ffff888115184248 [ +0.007154] FS: 0000000000000000(0000) GS:ffff88844db00000(0000) knlGS:0000000000000000 [ +0.008108] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ +0.005763] CR2: 0000000000000020 CR3: 000000013fdb4004 CR4: 00000000003706e0 [ +0.007152] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ +0.007145] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ +0.007154] Call Trace: [ +0.002459] <TASK> [ +0.002126] ttm_tt_unpopulate.part.0+0x17/0x70 [ttm] [ +0.005068] ttm_bo_tt_destroy+0x1c/0x50 [ttm] [ +0.004464] ttm_bo_cleanup_memtype_use+0x25/0x40 [ttm] [ +0.005244] ttm_bo_cleanup_refs+0x90/0x2c0 [ttm] [ +0.004721] ttm_bo_delayed_delete+0x235/0x250 [ttm] [ +0.004981] ttm_device_delayed_workqueue+0x13/0x40 [ttm] [ +0.005422] process_one_work+0x248/0x560 [ +0.004028] worker_thread+0x4b/0x390 [ +0.003682] ? process_one_work+0x560/0x560 [ +0.004199] kthread+0xeb/0x120 [ +0.003163] ? kthread_complete_and_exit+0x20/0x20 [ +0.004815] ret_from_fork+0x1f/0x30 v2: - Just use ttm_bo_wait() directly (Niranjana) - Add testcase reference Testcase: igt@gem_madvise@dontneed-evict-race Fixes: 213d50927763 ("drm/i915/ttm: Introduce a TTM i915 gem object backend") Reported-by: Niranjana Vishwanathapura <[email protected]> Signed-off-by: Matthew Auld <[email protected]> Cc: Andrzej Hajda <[email protected]> Cc: Nirmoy Das <[email protected]> Cc: <[email protected]> # v5.15+ Reviewed-by: Niranjana Vishwanathapura <[email protected]> Acked-by: Nirmoy Das <[email protected]> Reviewed-by: Andrzej Hajda <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

There were several updates in the driver on how the workarounds are handled since its documentation was written. Update the documentation to reflect the current reality. v2: - Remove footnote that was wrongly referenced, adding back the reference in the correct paragraph. - Remove "Display workarounds" and just mention "display IP" under "Other" category since all of them are peppered around the driver.
