The AGP subsystem supports a user-space interface via /dev/agpgart. It is only enabled with DRM support for mode setting in user space. (i.e., CONFIG_DRM_LEGACY). All of that DRM code has been removed and the option will go away. Hence remove the AGP frontend. Modern DRM drivers with kernel mode setting handle AGP support internally. Signed-off-by:

Modern DRM drivers acquire ioctl locks by themselves. Legacy ioctls for user-space mode setting used to acquire drm_global_mutex. After removing the ioctl entry points, also remove the locking code. The only legacy ioctl without global locking was VBLANK_WAIT, which has been removed as well. Hence remove the related DRM_UNLOCKED flag. Signed-off-by:

DRM drivers with user-space mode setting have been removed in Linux v6.3. [1] Now remove the ioctl entry points for these drivers. Invoking any of the ioctl ops will unconditionally return -EINVAL to user space. Invoking DRM_IOCTL_MODESET_CTL is different from the other legacy ioctl ops as it returns 0 even without CONFIG_DRM_LEGACY set. From the original commit 29935554 ("drm: Disallow DRM_IOCTL_MODESET_CTL for KMS drivers") it is not apparent how or why the operation differs from the others. It is likely just an oversight in commit 61ae2270 ("drm: allow removal of legacy codepaths (v4.1)"), which allowed disabling leagacy ioctls in the first place. Still keep this removal separate from the other ioctls to allow an easy revert, if necessary. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Reviewed-by:

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 Fixes: 22aa1a20 ("drm/panfrost: Really power off GPU cores in panfrost_gpu_power_off()") Reviewed-by:

Timings taken from the datasheet, although sometimes there are just typical values and it's not clear if they are no min and max values or if you must use the typical value exactly. To make things worse, there is no back porch but only a combined sync and back porch length. Unfortunately, there is not public datasheet. Therefore, here are the relevant timings: | min | typ | max | -----------------+-----+--------+-----+ CLK frequency | - | 25.175 | - | HS period | - | 800 | - | HS pulse width | 5 | 30 | - | HS-DEN time | 112 | 144 | 175 | DEN pulse width | - | 640 | - | VS pulse width | 1 | 3 | 5 | VS-DEN time | - | 35 | - | VS period | - | 525 | - | Signed-off-by:Michael Walle <mwalle@kernel.org> Reviewed-by:
