drm/scheduler: remove full_recover from drm_sched_start
This was basically just another one of amdgpus hacks. The parameter allowed to restart the scheduler without turning fence signaling on again. That this is absolutely not a good idea should be obvious by now since the fences will then just sit there and never signal. While at it cleanup the code a bit.

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: Fix dma_resv deadlock at drm object pin time
When Panfrost must pin an object that is being prepared a dma-buf
attachment for on behalf of another driver, the core drm gem object pinning
code already takes a lock on the object's dma reservation.
However, Panfrost GEM object's pinning callback would eventually try taking
the lock on the same dma reservation when delegating pinning of the object
onto the shmem subsystem, which led to a deadlock.
This can be shown by enabling CONFIG_DEBUG_WW_MUTEX_SLOWPATH, which throws
the following recursive locking situation:
weston/3440 is trying to acquire lock:
ffff000000e235a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: drm_gem_shmem_pin+0x34/0xb8 [drm_shmem_helper]
but task is already holding lock:
ffff000000e235a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: drm_gem_pin+0x2c/0x80 [drm]
Fix it by replacing drm_gem_shmem_pin with its locked version, as the lock
had already been taken by drm_gem_pin().

If some the pages or sgt allocation failed, we shouldn't release the
pages ref we got earlier, otherwise we will end up with unbalanced
get/put_pages() calls. We should instead leave everything in place
and let the BO release function deal with extra cleanup when the object

drm/panfrost: Synchronize and disable interrupts before powering off
To make sure that we don't unintentionally perform any unclocked and/or
unpowered R/W operation on GPU registers, before turning off clocks and
regulators we must make sure that no GPU, JOB or MMU ISR execution is
pending: doing that requires to add a mechanism to synchronize the
interrupts on suspend.
Add functions panfrost_{gpu,job,mmu}_suspend_irq() which will perform
interrupts masking and ISR execution synchronization, and then call
those in the panfrost_device_runtime_suspend() handler in the exact
sequence of job (may require mmu!) -> mmu -> gpu.
As a side note, JOB and MMU suspend_irq functions needed some special
treatment: as their interrupt handlers will unmask interrupts, it was
necessary to add an `is_suspended` bitmap which is used to address the
possible corner case of unintentional IRQ unmasking because of ISR
execution after a call to synchronize_irq().
At resume, clear each is_suspended bit in the reset path of JOB/MMU
to allow unmasking the interrupts.

drm/panfrost: Ignore core_mask for poweroff and disable PWRTRANS irq
Some SoCs may be equipped with a GPU containing two core groups
and this is exactly the case of Samsung's Exynos 5422 featuring
an ARM Mali-T628 MP6 GPU: the support for this GPU in Panfrost
is partial, as this driver currently supports using only one
core group and that's reflected on all parts of it, including
the power on (and power off, previously to this patch) function.
The issue with this is that even though executing the soft reset
operation should power off all cores unconditionally, on at least
one platform we're seeing a crash that seems to be happening due
to an interrupt firing which may be because we are calling power
transition only on the first core group, leaving the second one
unchanged, or because ISR execution was pending before entering
the panfrost_gpu_power_off() function and executed after powering
off the GPU cores, or all of the above.
Finally, solve this by:
- Avoid to enable the power transition interrupt on reset; and
- Ignoring the core_mask and ask the GPU to poweroff both core groups

drm/panfrost: Fix incorrect updating of current device frequency
It was noticed when setting the Panfrost's DVFS device to the performant
governor, GPU frequency as reported by fdinfo had dropped to 0 permamently.
There are two separate issues causing this behaviour:
- Not initialising the device's current_frequency variable to its original
value during device probe().
- Updating said variable in Panfrost devfreq's get_dev_status() rather
than after the new OPP's frequency had been retrieved in target(), which
meant the old frequency would be assigned instead.

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/panfrost: Implement ability to turn on/off GPU clocks in suspend
Currently, the GPU is being internally powered off for runtime suspend and turned back on for runtime resume through commands sent to it, but note that the GPU doesn't need to be clocked during the poweroff state, hence it is possible to save some power on selected platforms. Add suspend and resume handlers for full system sleep and then add a new panfrost_gpu_pm enumeration and a pm_features variable in the panfrost_compatible structure: BIT(GPU_PM_CLK_DIS) will be used to enable this power saving technique only on SoCs that are able to safely use it. Note that this was implemented only for the system sleep case and not for runtime PM because testing on one of my MediaTek platforms showed issues when turning on and off clocks aggressively (in PM runtime) resulting in a full system lockup. Doing this only for full system sleep never showed issues during my testing by suspending and resuming the system continuously for more than 100 cycles.

drm/panfrost: Tighten polling for soft reset and power on
In many cases, soft reset takes more than 1 microsecond, but definitely less than 10; moreover in the poweron flow, tilers, shaders and l2 will become ready (each) in less than 10 microseconds as well. Even in the cases (at least on my platforms, rarely) in which those take more than 10 microseconds, it's very unlikely to see both soft reset and poweron to take more than 70 microseconds. Shorten the polling delay to 10 microseconds to consistently reduce the runtime resume time of the GPU.

drm/panfrost: Perform hard reset to recover GPU if soft reset fails
Even though soft reset should ideally never fail, during development of some power management features I managed to get some bits wrong: this resulted in GPU soft reset failures, where the GPU was never able to recover, not even after suspend/resume cycles, meaning that the only way to get functionality back was to reboot the machine. Perform a hard reset after a soft reset failure to be able to recover the GPU during runtime (so, without any machine reboot).

drm/panfrost: Really power off GPU cores in panfrost_gpu_power_off()
The layout of the registers {TILER,SHADER,L2}_PWROFF_LO, used to request
powering off cores, is the same as the {TILER,SHADER,L2}_PWRON_LO ones:
this means that in order to request poweroff of cores, we are supposed
to write a bitmask of cores that should be powered off!
This means that the panfrost_gpu_power_off() function has always been
doing nothing.
Fix powering off the GPU by writing a bitmask of the cores to poweroff
to the relevant PWROFF_LO registers and then check that the transition
(from ON to OFF) has finished by polling the relevant PWRTRANS_LO
registers.
While at it, in order to avoid code duplication, move the core mask
logic from panfrost_gpu_power_on() to a new panfrost_get_core_mask()
function, used in both poweron and poweroff.
Fixes:

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/sched: Convert drm scheduler to use a work queue rather than kthread
In Xe, the new Intel GPU driver, a choice has made to have a 1 to 1 mapping between a drm_gpu_scheduler and drm_sched_entity. At first this seems a bit odd but let us explain the reasoning below. 1. In Xe the submission order from multiple drm_sched_entity is not guaranteed to be the same completion even if targeting the same hardware engine. This is because in Xe we have a firmware scheduler, the GuC, which allowed to reorder, timeslice, and preempt submissions. If a using shared drm_gpu_scheduler across multiple drm_sched_entity, the TDR falls apart as the TDR expects submission order == completion order. Using a dedicated drm_gpu_scheduler per drm_sched_entity solve this problem. 2. In Xe submissions are done via programming a ring buffer (circular buffer), a drm_gpu_scheduler provides a limit on number of jobs, if the limit of number jobs is set to RING_SIZE / MAX_SIZE_PER_JOB we get flow control on the ring for free. A problem with this design is currently a drm_gpu_scheduler uses a kthread for submission / job cleanup. This doesn't scale if a large number of drm_gpu_scheduler are used. To work around the scaling issue, use a worker rather than kthread for submission / job cleanup. v2: - (Rob Clark) Fix msm build - Pass in run work queue v3: - (Boris) don't have loop in worker v4: - (Tvrtko) break out submit ready, stop, start helpers into own patch v5: - (Boris) default to ordered work queue v6: - (Luben / checkpatch) fix alignment in msm_ringbuffer.c - (Luben) s/drm_sched_submit_queue/drm_sched_wqueue_enqueue - (Luben) Update comment for drm_sched_wqueue_enqueue - (Luben) Positive check for submit_wq in drm_sched_init - (Luben) s/alloc_submit_wq/own_submit_wq v7: - (Luben) s/drm_sched_wqueue_enqueue/drm_sched_run_job_queue v8: - (Luben) Adjust var names / comments Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Link: https://lore.kernel.org/r/20231031032439.1558703-3-matthew.brost@intel.com Signed-off-by: Luben Tuikov <ltuikov89@gmail.com> |

drm/sched: Convert the GPU scheduler to variable number of run-queues
The GPU scheduler has now a variable number of run-queues, which are set up at drm_sched_init() time. This way, each driver announces how many run-queues it requires (supports) per each GPU scheduler it creates. Note, that run-queues correspond to scheduler "priorities", thus if the number of run-queues is set to 1 at drm_sched_init(), then that scheduler supports a single run-queue, i.e. single "priority". If a driver further sets a single entity per run-queue, then this creates a 1-to-1 correspondence between a scheduler and a scheduled entity.

drm/panfrost: Implement generic DRM object RSS reporting function
BO's RSS is updated every time new pages are allocated on demand and mapped for the object at GPU page fault's IRQ handler, but only for heap buffers. The reason this is unnecessary for non-heap buffers is that they are mapped onto the GPU's VA space and backed by physical memory in their entirety at BO creation time. This calculation is unnecessary for imported PRIME objects, since heap buffers cannot be exported by our driver, and the actual BO RSS size is the one reported in its attached dmabuf structure.

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.

Clear all assignments of struct drm_driver's fd/handle callbacks to drm_gem_prime_fd_to_handle() and drm_gem_prime_handle_to_fd(). These functions are called by default. Add a TODO item to convert vmwgfx to the defaults as well. v2: * remove TODO item (Zack) * also update amdgpu's amdgpu_partition_driver Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Simon Ser <contact@emersion.fr> Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Jeffrey Hugo <quic_jhugo@quicinc.com> # qaic Link: https://patchwork.freedesktop.org/patch/msgid/20230620080252.16368-3-tzimmermann@suse.de |

drm/shmem-helper: Switch to reservation lock
Replace all drm-shmem locks with a GEM reservation lock. This makes locks consistent with dma-buf locking convention where importers are responsible for holding reservation lock for all operations performed over dma-bufs, preventing deadlock between dma-buf importers and exporters.

drm: Remove struct drm_driver.gem_prime_mmap
All drivers initialize this field with drm_gem_prime_mmap(). Call the function directly and remove the field. Simplifies the code and resolves a long-standing TODO item.

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 basic support for speed binning
Some SoCs implementing ARM Mali GPUs are subject to speed binning: this means that some versions of the same SoC model may need to be limited to a slower frequency compared to the other: this is being addressed by reading nvmem (usually, an eFuse array) containing a number that identifies the speed binning of the chip, which is usually related to silicon quality. To address such situation, add basic support for reading the speed-bin through nvmem, as to make it possible to specify the supported hardware in the OPP table for GPUs. This commit also keeps compatibility with any platform that does not specify (and does not even support) speed-binning.
