drm/panfrost: Add support for Mali on the MT8370 SoC
Add a compatible for the MediaTek MT8370 SoC, with an integrated ARM Mali G57 MC2 GPU (Valhall-JM, dual core), with new platform data for its support in the panfrost driver. It uses the same data as MT8186 for the power management features to describe power supplies, pm_domains and enablement (one regulator, two power domains) but also sets the FORCE_AARCH64_PGTABLE flag in the GPU configuration quirks bitfield to enable AARCH64 4K page table format mode. As MT8186 and MT8370 SoC have different GPU architecture (Mali G52 2EE MC2 for MT8186), making them not compatible, and this mode is only enabled for Mediatek SoC that are Mali G57 based (compatible with mediatek,mali-mt8188 or mediatek,mali-8192), having specific platform data allows to set this flag for MT8370 without modifying MT8186 configuration and behaviour.

drm/panfrost: Commonize Mediatek power domain array definitions
In the panfrost driver, the platform data of several Mediatek SoC declares and uses several different power domains arrays according to GPU core number present in the SoC: - mediatek_mt8186_pm_domains (2 cores) - mediatek_mt8183_pm_domains (3 cores) - mediatek_mt8192_pm_domains (5 cores) As they all are fixed arrays, starting with the same entries and the platform data also has a power domains array length field (num_pm_domains), they can be replaced by a single array, containing all entries, if the num_pm_domains field of the platform data is also set to the matching core number. So, create a generic power domain array (mediatek_pm_domains) and use it in the mt8183(b), mt8186, mt8188 and mt8192 platform data instead.

drm/panfrost: Drop duplicated Mediatek supplies arrays
In the panfrost driver, the platform data of several Mediatek SoC declares and uses custom supplies array definitions (mediatek_mt8192_supplies, mediatek_mt8183_b_supplies), that are the same as default_supplies (used by default platform data). So drop these duplicated definitions and use default_supplies instead. Also, rename mediatek_mt8183_supplies to a more generic name too (legacy_supplies).

drm/sched: Store the drm client_id in drm_sched_fence
This will be used in a later commit to trace the drm client_id in some of the gpu_scheduler trace events. This requires changing all the users of drm_sched_job_init to add an extra parameter. The newly added drm_client_id field in the drm_sched_fence is a bit of a duplicate of the owner one. One suggestion I received was to merge those 2 fields - this can't be done right now as amdgpu uses some special values (AMDGPU_FENCE_OWNER_*) that can't really be translated into a client id. Christian is working on getting rid of those; when it's done we should be able to squash owner/drm_client_id together.

drm/panfrost: Force AARCH64_4K page table format on MediaTek MT8188
MediaTek MT8188 SoC has an ARM Mali-G57 MC3 GPU (Valhall-JM), which constantly faults with the current panfrost support. For instance, running `glmark2-es2-drm` benchmark test: ``` [ 79.617461] panfrost 13000000.gpu: js fault, js=1, status=JOB_BUS_FAULT, head=0xaadc380, tail=0xaadc380 [ 80.119811] panfrost 13000000.gpu: gpu sched timeout, js=0, config=0x7300, status=0x58, head=0xaaca180, tail=0xaaca180, sched_job=000000002fd03ccc [ 80.129083] panfrost 13000000.gpu: Unhandled Page fault in AS0 at VA 0x0000000000000000 [ 80.129083] Reason: TODO [ 80.129083] raw fault status: 0x1C2 [ 80.129083] decoded fault status: SLAVE FAULT [ 80.129083] exception type 0xC2: TRANSLATION_FAULT_2 [ 80.129083] access type 0x1: EXECUTE [ 80.129083] source id 0x0 ``` Note that current panfrost mode (Mali LPAE - LEGACY) only allows to specify write-cache or implementation-defined as the caching policy, probably not matching the right configuration. As depicted in the source code: drivers/iommu/io-pgtable-arm.c: ``` * MEMATTR: Mali has no actual notion of a non-cacheable type, so the * best we can do is mimic the out-of-tree driver and hope that the * "implementation-defined caching policy" is good enough... ``` Now that Panfrost supports AARCH64_4K page table format, let's enable it on Mediatek MT8188 and configure the cache/shareability policies properly.

Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

drm/panfrost: Add cycle counter job requirement
Extend the uAPI with a new job requirement flag for cycle counters. This requirement is used by userland to indicate that a job requires cycle counters or system timestamp to be propagated. (for use with write value timestamp jobs) We cannot enable cycle counters unconditionally as this would result in an increase of GPU power consumption. As a result, they should be left off unless required by the application. If a job requires cycle counters or system timestamps propagation, we must enable cycle counting before issuing a job and disable it right after the job completes. Since this extends the uAPI and because userland needs a way to advertise features like VK_KHR_shader_clock conditionally, we bumps the driver minor version. v2: - Rework commit message - Squash uAPI changes and implementation in this commit - Simplify changes based on Steven Price comments v3: - Add Steven Price r-b - Fix a codestyle issue Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240819080224.24914-3-mary.guillemard@collabora.com |

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: 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.

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. Readd it to make things compile. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |

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.

OPP: Make dev_pm_opp_set_regulators() accept NULL terminated list
Make dev_pm_opp_set_regulators() accept a NULL terminated list of names instead of making the callers keep the two parameters in sync, which creates an opportunity for bugs to get in.

drm/panfrost: Fix shrinker list corruption by madvise IOCTL
Calling madvise IOCTL twice on BO causes memory shrinker list corruption
and crashes kernel because BO is already on the list and it's added to
the list again, while BO should be removed from the list before it's
re-added. Fix it.
