2023-03-23drm/panfrost: Add support for Mali on the MT8186 SoCAngeloGioacchino Del Regno1-0/+9
MediaTek MT8186 has a Mali-G52 MC2 2EE (Bifrost): add a new compatible and platform data using the same supplies list as "mt8183_b" (only one regulator), and a new pm_domains list with only two power domains.

2023-03-23drm/panfrost: Add new compatible for Mali on the MT8183 SoCAngeloGioacchino Del Regno1-0/+17
The "mediatek,mt8183-mali" compatible uses platform data that calls for getting (and managing) two regulators ("mali" and "sram") but devfreq does not support this usecase, resulting in DVFS not working. Since a lot of MediaTek SoCs need to set the voltages for the GPU SRAM regulator in a specific relation to the GPU VCORE regulator, a MediaTek SoC specific driver was introduced to automatically satisfy, through coupling, these constraints: this means that there is at all no need to manage both regulators in panfrost but to otherwise just manage the main "mali" (-> gpu vcore) regulator instead. Keeping in mind that we cannot break the ABI, the most sensible route (avoiding hacks and uselessly overcomplicated code) to get a MT8183 node with one power supply was to add a new "mediatek,mt8183b-mali" compatible, which effectively deprecates the former.

This reverts commit 67b7836d4458790f1261e31fe0ce3250989784f0. The locking appears incomplete. A caller of SHMEM helper's pin function never acquires the dma-buf reservation lock.

Replace all drm-shmem locks with a GEM reservation lock.

Due to holidays we started -next with more -fixes in-flight than usual, and people have been asking where they are. Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable.

2022-12-21drm/panfrost: Fix GEM handle creation ref-countingSteven Price1-9/+18
panfrost_gem_create_with_handle() previously returned a BO but with the only reference being from the handle, which user space could in theory guess and release, causing a use-after-free. Additionally if the call to panfrost_gem_mapping_get() in panfrost_ioctl_create_bo() failed then a(nother) reference on the BO was dropped. The _create_with_handle() is a problematic pattern, so ditch it and instead create the handle in panfrost_ioctl_create_bo(). If the call to panfrost_gem_mapping_get() fails then this means that user space has indeed gone behind our back and freed the handle. In which case just return an error code.

2022-12-12drm: panfrost: Remove #ifdef guards for PM related functionsPaul Cercueil1-6/+1
Use the EXPORT_GPL_RUNTIME_DEV_PM_OPS() and pm_ptr() macros to handle the PM callbacks. These macros allow the PM functions to be automatically dropped by the compiler when CONFIG_PM is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

Jobs can be in-flight when the file descriptor is closed (either because the process did not terminate properly, or because it didn't wait for all GPU jobs to be finished), and apparently panfrost_job_close() does not cancel already running jobs.

2021-06-04drm/panfrost: Add AFBC_FEATURES parameterAlyssa Rosenzweig1-1/+3
The value of the AFBC_FEATURES register is required by userspace to determine AFBC support on Bifrost. A user on our IRC channel (#panfrost) reported a workload that raised a fault on one system's Mali G31 but worked flawlessly with another system's Mali G31. We determined the cause to be missing AFBC support on one vendor's Mali implementation -- it turns out AFBC is optional on Bifrost! Whether AFBC is supported or not is exposed in the AFBC_FEATURES register on Bifrost, which reads back as 0 on Midgard. A zero value indicates AFBC is fully supported, provided the architecture itself supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and 15 indicate that AFBC support is absent for texturing and rendering respectively. The user experiencing the fault reports that AFBC_FEATURES reads back 0x10001 on their system, confirming the architectural lack of AFBC. Userspace needs this parameter to know to disable AFBC on that chip, and perhaps others. v2: Fix typo from copy-paste fail. v3: Bump the UABI version. This commit was cherry-picked from another series so chalking this up to a rebase fail.

2020-01-21drm/panfrost: Add the panfrost_gem_mapping conceptBoris Brezillon1-9/+82
With the introduction of per-FD address space, the same BO can be mapped in different address space if the BO is globally visible (GEM_FLINK) and opened in different context or if the dmabuf is self-imported. The current implementation does not take case into account, and attaches the mapping directly to the panfrost_gem_object. Let's create a panfrost_gem_mapping struct and allow multiple mappings per BO. The mappings are refcounted which helps solve another problem where mappings were torn down (GEM handle closed by userspace) while GPU jobs accessing those BOs were still in-flight. Jobs now keep a reference on the mappings they use. v2 (robh): - Minor review comment clean-ups from Steven - Use list_is_singular helper - Just WARN if we add a mapping when madvise state is not WILLNEED. With that, drop the use of object_name_lock. v3 (robh): - Revert returning list iterator in panfrost_gem_mapping_get() Fixes: a5efb4c9a562 ("drm/panfrost: Restructure the GEM object creation") Fixes: 7282f7645d06 ("drm/panfrost: Implement per FD address spaces") Cc: <stable@vger.kernel.org> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Rob Herring <robh@kernel.org> Acked-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200116021554.15090-1-robh@kernel.org

Commit a5efb4c9a562 ("drm/panfrost: Restructure the GEM object creation") moved the drm_mm_insert_node_generic() call to the gem->open() hook, but forgot to update perfcnt accordingly. Patch the perfcnt logic to call panfrost_gem_open/close() where appropriate.
