2024-02-23drm/bridge: aux-hpd: separate allocation and registrationJohan Hovold1-0/+15
Combining allocation and registration is an anti-pattern that should be avoided. Add two new functions for allocating and registering an dp-hpd bridge with a proper 'devm' prefix so that it is clear that these are device managed interfaces. devm_drm_dp_hpd_bridge_alloc() devm_drm_dp_hpd_bridge_add() The new interface will be used to fix a use-after-free bug in the Qualcomm PMIC GLINK driver and may prevent similar issues from being introduced elsewhere. The existing drm_dp_hpd_bridge_register() is reimplemented using the above and left in place for now.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference. Otherwise it's the usual lots of changes in lots of places.

The experimental support starts with Tiger Lake. i915 will continue be the main production driver for the platforms up to Meteor Lake and Alchemist. Then the goal is to make this Intel Xe driver the primary driver for Lunar Lake and newer platforms. It uses most, if not all, of the key drm concepts, in special: TTM, drm-scheduler, drm-exec, drm-gpuvm/gpuva and others.

2023-12-21drm/xe: Sync MTL PCI IDs with i915Lucas De Marchi1-23/+4
For Xe1 platforms, it's better to follow the way i915 adds the PCI IDs to the header, so it's easier to catch up when there is an update. This brings the same logic applied in commit 2e3c369f23a7 ("drm/i915/mtl: Eliminate subplatforms") to the equivalent xe header. The end result of this header for Xe1 platforms is now in sync with i915 as of commit 5032c607e886 ("drm/i915: ATS-M device ID update").

2023-12-12drm/xe: Introduce a new DRM driver for Intel GPUsMatthew Brost1-0/+195
Xe, is a new driver for Intel GPUs that supports both integrated and discrete platforms starting with Tiger Lake (first Intel Xe Architecture). The code is at a stage where it is already functional and has experimental support for multiple platforms starting from Tiger Lake, with initial support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan drivers), as well as in NEO (for OpenCL and Level0). The new Xe driver leverages a lot from i915. As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. But it is not added in this patch. This initial work is a collaboration of many people and unfortunately the big squashed patch won't fully honor the proper credits. But let's get some git quick stats so we can at least try to preserve some of the credits: Co-developed-by: Matthew Brost <matthew.brost@intel.com> Co-developed-by: Matthew Auld <matthew.auld@intel.com> Co-developed-by: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Co-developed-by: Francois Dugast <francois.dugast@intel.com> Co-developed-by: Lucas De Marchi <lucas.demarchi@intel.com> Co-developed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Co-developed-by: Philippe Lecluse <philippe.lecluse@intel.com> Co-developed-by: Nirmoy Das <nirmoy.das@intel.com> Co-developed-by: Jani Nikula <jani.nikula@intel.com> Co-developed-by: José Roberto de Souza <jose.souza@intel.com> Co-developed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Co-developed-by: Dave Airlie <airlied@redhat.com> Co-developed-by: Faith Ekstrand <faith.ekstrand@collabora.com> Co-developed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Co-developed-by: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com>

2023-12-07drm/mipi-dsi: Fix detach call without attachTomi Valkeinen1-0/+2
It's been reported that DSI host driver's detach can be called without the attach ever happening: https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/ After reading the code, I think this is what happens: We have a DSI host defined in the device tree and a DSI peripheral under that host (i.e. an i2c device using the DSI as data bus doesn't exhibit this behavior). The host driver calls mipi_dsi_host_register(), which causes (via a few functions) mipi_dsi_device_add() to be called for the DSI peripheral. So now we have a DSI device under the host, but attach hasn't been called. Normally the probing of the devices continues, and eventually the DSI peripheral's driver will call mipi_dsi_attach(), attaching the peripheral. However, if the host driver's probe encounters an error after calling mipi_dsi_host_register(), and before the peripheral has called mipi_dsi_attach(), the host driver will do cleanups and return an error from its probe function. The cleanups include calling mipi_dsi_host_unregister(). mipi_dsi_host_unregister() will call two functions for all its DSI peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister(). The latter makes sense, as the device exists, but the former may be wrong as attach has not necessarily been done. To fix this, track the attached state of the peripheral, and only detach from mipi_dsi_host_unregister() if the peripheral was attached. Note that I have only tested this with a board with an i2c DSI peripheral, not with a "pure" DSI peripheral. However, slightly related, the unregister machinery still seems broken. E.g. if the DSI host driver is unbound, it'll detach and unregister the DSI peripherals. After that, when the DSI peripheral driver unbound it'll call detach either directly or using the devm variant, leading to a crash. And probably the driver will crash if it happens, for some reason, to try to send a message via the DSI bus. But that's another topic. Tested-by: H.

2023-12-06drm/atomic-helpers: Invoke end_fb_access while owning plane stateThomas Zimmermann1-0/+2
Invoke drm_plane_helper_funcs.end_fb_access before drm_atomic_helper_commit_hw_done(). The latter function hands over ownership of the plane state to the following commit, which might free it. Releasing resources in end_fb_access then operates on undefined state. This bug has been observed with non-blocking commits when they are being queued up quickly. Here is an example stack trace from the bug report. The plane state has been free'd already, so the pages for drm_gem_fb_vunmap() are gone. Unable to handle kernel paging request at virtual address 0000000100000049 [...] drm_gem_fb_vunmap+0x18/0x74 drm_gem_end_shadow_fb_access+0x1c/0x2c drm_atomic_helper_cleanup_planes+0x58/0xd8 drm_atomic_helper_commit_tail+0x90/0xa0 commit_tail+0x15c/0x188 commit_work+0x14/0x20 Fix this by running end_fb_access immediately after updating all planes in drm_atomic_helper_commit_planes(). The existing clean-up helper drm_atomic_helper_cleanup_planes() now only handles cleanup_fb. For aborted commits, roll back from drm_atomic_helper_prepare_planes() in the new helper drm_atomic_helper_unprepare_planes(). This case is different from regular cleanup, as we have to release the new state; regular cleanup releases the old state. The new helper also invokes cleanup_fb for all planes. The changes mostly involve DRM's atomic helpers. Only two drivers, i915 and nouveau, implement their own commit function. Update them to invoke drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail function do not require changes. v4: * fix documentation (kernel test robot) v3: * add drm_atomic_helper_unprepare_planes() for rolling back * use correct state for end_fb_access v2: * fix test in drm_atomic_helper_cleanup_planes() Reported-by: Alyssa Ross <hi@alyssa.is> Closes: https://lore.kernel.org/dri-devel/87leazm0ya.fsf@alyssa.is/ Suggested-by: Daniel Vetter <daniel@ffwll.ch> Fixes: 94d879eaf7fb ("drm/atomic-helper: Add {begin,end}_fb_access to plane helpers") Tested-by: Alyssa Ross <hi@alyssa.is> Reviewed-by: Alyssa Ross <hi@alyssa.is> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: <stable@vger.kernel.org> # v6.2+ Link: https://patchwork.freedesktop.org/patch/msgid/20231204083247.22006-1-tzimmermann@suse.de

2023-12-05drm/gpuvm: Let drm_gpuvm_bo_put() report when the vm_bo object is destroyedBoris Brezillon1-1/+1
Some users need to release resources attached to the vm_bo object when it's destroyed. In Panthor's case, we need to release the pin ref so BO pages can be returned to the system when all GPU mappings are gone. This could be done through a custom drm_gpuvm::vm_bo_free() hook, but this has all sort of locking implications that would force us to expose a drm_gem_shmem_unpin_locked() helper, not to mention the fact that having a ::vm_bo_free() implementation without a ::vm_bo_alloc() one seems odd. So let's keep things simple, and extend drm_gpuvm_bo_put() to report when the object is destroyed.

2023-12-04drm/bridge: migrate bridge_chains to per-encoder fileDmitry Baryshkov1-2/+0
Instead of having a single file with all bridge chains, list bridges under a corresponding per-encoder debugfs directory. While we are at it, also slightly improve the formatting of the bridge data: split a single line entry into multiple lines, include the symbol name of the bridge funcs and add the textual representation of the bridge ops. Example of the listing: $ cat /sys/kernel/debug/dri/0/encoder-0/bridges bridge[0]: dsi_mgr_bridge_funcs type: [0] Unknown ops: [0] bridge[1]: lt9611uxc_bridge_funcs type: [11] HDMI-A OF: /soc@0/geniqup@9c0000/i2c@994000/hdmi-bridge@2b:lontium,lt9611uxc ops: [7] detect edid hpd Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20231203115315.1306124-3-dmitry.baryshkov@linaro.org
2023-12-04drm/encoder: register per-encoder debugfs dirDmitry Baryshkov1-1/+15
Each of connectors and CRTCs used by the DRM device provides debugfs directory, which is used by several standard debugfs files and can further be extended by the driver. Add such generic debugfs directories for encoder.
