drm/panfrost: Mark simple_ondemand governor as softdep
Panfrost DRM driver uses devfreq to perform DVFS, while using simple_ondemand devfreq governor by default. This causes driver initialization to fail on boot when simple_ondemand governor isn't built into the kernel statically, as a result of the missing module dependency and, consequently, the required governor module not being included in the initial ramdisk. Thus, let's mark simple_ondemand governor as a softdep for Panfrost, to have its kernel module included in the initial ramdisk. This is a rather longstanding issue that has forced distributions to build devfreq governors statically into their kernels, [1][2] or has forced users to introduce some unnecessary workarounds. [3] For future reference, not having support for the simple_ondemand governor in the initial ramdisk produces errors in the kernel log similar to these below, which were taken from a Pine64 RockPro64: panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq panfrost ff9a0000.gpu: Fatal error during GPU init panfrost: probe of ff9a0000.gpu failed with error -22 Having simple_ondemand marked as a softdep for Panfrost may not resolve this issue for all Linux distributions. In particular, it will remain unresolved for the distributions whose utilities for the initial ramdisk generation do not handle the available softdep information [4] properly yet. However, some Linux distributions already handle softdeps properly while generating their initial ramdisks, [5] and this is a prerequisite step in the right direction for the distributions that don't handle them properly yet.

drm/panfrost: Only display fdinfo's engine and cycle tags when profiling is on
If job accounting is disabled, then both fdinfo's drm-engine and drm-cycle key values will remain immutable.

drm/panfrost: Replace fdinfo's profiling debugfs knob with sysfs
Debugfs isn't always available in production builds that try to squeeze every single byte out of the kernel image, but we still need a way to toggle the timestamp and cycle counter registers so that jobs can be profiled for fdinfo's drm engine and cycle calculations. Drop the debugfs knob and replace it with a sysfs file that accomplishes the same functionality, and document its ABI in a separate file.

drm/panfrost: Set regulators on/off during system sleep on MediaTek SoCs
All of the MediaTek SoCs supported by Panfrost can completely cut power to the GPU during full system sleep without any user-noticeable delay in the resume operation, as shown by measurements taken on multiple MediaTek SoCs (MT8183/86/92/95). As an example, for MT8195 - a "before" with only runtime PM operations (so, without turning on/off regulators), and an "after" executing both the system sleep .resume() handler and .runtime_resume() (so the time refers to T_Resume + T_Runtime_Resume): Average Panfrost-only system sleep resume time, before: ~33500ns Average Panfrost-only system sleep resume time, after: ~336200ns Keep in mind that this additional ~308200 nanoseconds delay happens only in resume from a full system suspend, and not in runtime PM operations, hence it is acceptable. Measurements were also taken on MT8186, showing a delay of ~312000 ns. Testing of this happened on all of the aforementioned MediaTek SoCs, but: MT8183 got tested only by KernelCI with <=10 suspend/resume cycles MT8186, MT8192, MT8195 were tested manually with over 100 suspend/resume cycles with GNOME DE (Mutter + Wayland).

drm/sched: implement dynamic job-flow control
Currently, job flow control is implemented simply by limiting the number of jobs in flight. Therefore, a scheduler is initialized with a credit limit that corresponds to the number of jobs which can be sent to the hardware. This implies that for each job, drivers need to account for the maximum job size possible in order to not overflow the ring buffer. However, there are drivers, such as Nouveau, where the job size has a rather large range. For such drivers it can easily happen that job submissions not even filling the ring by 1% can block subsequent submissions, which, in the worst case, can lead to the ring run dry. In order to overcome this issue, allow for tracking the actual job size instead of the number of jobs. Therefore, add a field to track a job's credit count, which represents the number of credits a job contributes to the scheduler's credit limit.

drm/panfrost: Add fdinfo support for memory stats
A new DRM GEM object function is added so that drm_show_memory_stats can provide more accurate memory usage numbers. Ideally, in panfrost_gem_status, the BO's purgeable flag would be checked after locking the driver's shrinker mutex, but drm_show_memory_stats takes over the drm file's object handle database spinlock, so there's potential for a race condition here.

drm/panfrost: Add fdinfo support GPU load metrics
The drm-stats fdinfo tags made available to user space are drm-engine, drm-cycles, drm-max-freq and drm-curfreq, one per job slot. This deviates from standard practice in other DRM drivers, where a single set of key:value pairs is provided for the whole render engine. However, Panfrost has separate queues for fragment and vertex/tiler jobs, so a decision was made to calculate bus cycles and workload times separately. Maximum operating frequency is calculated at devfreq initialisation time. Current frequency is made available to user space because nvtop uses it when performing engine usage calculations. It is important to bear in mind that both GPU cycle and kernel time numbers provided are at best rough estimations, and always reported in excess from the actual figure because of two reasons: - Excess time because of the delay between the end of a job processing, the subsequent job IRQ and the actual time of the sample. - Time spent in the engine queue waiting for the GPU to pick up the next job. To avoid race conditions during enablement/disabling, a reference counting mechanism was introduced, and a job flag that tells us whether a given job increased the refcount. This is necessary, because user space can toggle cycle counting through a debugfs file, and a given job might have been in flight by the time cycle counting was disabled. The main goal of the debugfs cycle counter knob is letting tools like nvtop or IGT's gputop switch it at any time, to avoid power waste in case no engine usage measuring is necessary. Also add a documentation file explaining the possible values for fdinfo's engine keystrings and Panfrost-specific drm-curfreq-<keystr> pairs.

drm: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

drm/panfrost: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

drm/panfrost: Add new compatible for Mali on the MT8183 SoC
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.

drm/panfrost: Fix GEM handle creation ref-counting
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.

drm: panfrost: Remove #ifdef guards for PM related functions
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.

and crashes kernel because BO is already on the list and it's added to

drm/panfrost: Job should reference MMU not file_priv
For a while now it's been allowed for a MMU context to outlive it's
corresponding panfrost_priv, however the job structure still references
panfrost_priv to get hold of the MMU context. If panfrost_priv has been
freed this is a use-after-free which I've been able to trigger resulting
in a splat.
To fix this, drop the reference to panfrost_priv in the job structure
and add a direct reference to the MMU structure which is what's actually
needed.

dma-buf: add enum dma_resv_usage v4
This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.

drm/shmem-helper: Pass GEM shmem object in public interfaces
Change all GEM SHMEM object functions that receive a GEM object of type struct drm_gem_object to expect an object of type struct drm_gem_shmem_object instead. This change reduces the number of upcasts from struct drm_gem_object by moving them into callers. The C compiler can now verify that the GEM SHMEM functions are called with the correct type. For consistency, the patch also renames drm_gem_shmem_free_object to drm_gem_shmem_free.

drm/panfrost: Make sure MMU context lifetime is not bound to panfrost_priv
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. Let's refcount the MMU context object
so it's lifetime is no longer bound to the FD lifetime and running jobs
can finish properly without generating spurious page faults.

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.

drm/<drivers>: Constify struct drm_driver
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: kernel test robot <lkp@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Dave Airlie <airlied@redhat.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Eric Anholt <eric@anholt.net> Cc: Maxime Ripard <mripard@kernel.org> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch |
