2018-08-03drm/vkms: Implement CRC debugfs APIHaneen Mohammed6-9/+196
This patch implement the necessary functions to compute and add CRCs entries: - Implement the set_crc_source() callback. - Compute CRC using crc32 on the visible part of the framebuffer. - Use ordered workqueue per output to compute and add CRC at the end of a vblank. - Use appropriate synchronization methods since the CRC computation must be atomic wrt the generated vblank event for a given atomic update, by using spinlock across atomic_begin/atomic_flush to wrap the event handling code completely and match the flip event with the CRC. Since vkms_crc_work_handle() can sleep, spinlock can't be acquired while accessing vkms_output->primary_crc to compute CRC. To make sure the data is updated and released without conflict with the vkms_crc_work_handle(), the work_struct is flushed @crtc_destroy and the data is updated before scheduling the work handle again, as follow: * CRC data update: 1- store vkms_crc_data {fb, src} per plane_state 2- @plane_duplicate_state -> allocate vkms_crc_data 3- during atomic commit (@atomic_update) -> a) copy {fb, src} to plane_state->crc_data b) get reference to fb, 3- @plane_destroy_state -> a) if (fb refcount) remove reference to fb b) deallocate crc_data * Atomic Commit: 1- vkms_plane_atomic_check 2- vkms_prepare_fb -> vmap vkms_gem_obj->vaddr 3- atomic_begin -> hold crc spinlock 4- atomic_plane_update -> a) update vkms_output->primary_crc b) get reference to fb 5- atomic_flush -> a) send vblank event while holding event_lock b) release crc spinlock * hrtimer regular callback: 1- hold crc spinlock 2- drm_crtc_handle_vblank() 3- queue vkms_crc_work_handle 4- release crc spinlock * cleanup: 1- @cleanup_fb ->vunmap vkms_gem_obj->vaddr 2- @crtc_destroy -> flush work struct 3- @plane_destroy -> a) if (fb refcount) remove reference to fb b) deallocate crc_data Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com> [seanpaul fixed typo in vkms_crtc s/vblamk/vblank/] Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/b948327f48c3e70ab232b4a0848ee6d033b26484.1533171495.git.hamohammed.sa@gmail.com

2018-08-03gpu: drm: msm: Change return type to vm_fault_tSouptick Joarder2-24/+11
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_mixed() returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_mixed() will replace this inefficiency by returning VM_FAULT_* type. vmf_error() is the newly introduce inline function in 4.17-rc6.

2018-08-02drm/i915/icl: avoid unclaimed PLANE_NV12_BUF_CFG registerPaulo Zanoni1-1/+7
We don't have proper watermark NV12 support on ICL due to differences in how it should be implemented. In commit 234059da0f33 ("drm/i915/icl: NV12 y-plane ddb is not in same plane") we avoided writing the non-existent PLANE_NV12_BUF_CFG registers but we forgot to also avoid them on the hardware state readout. While the code is still not correct, at least now we can avoid unclaimed register error messages when dealing with RGB formats, which makes CI happier. Also add some FIXME comments in order to make it even more clear that there's still work to do.

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. v2: * set prefix to drm/amdgpu Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-07-31drm/scheduler: stop setting rq to NULLChristian König1-27/+8
We removed the redundancy of having an extra scheduler field, so we can't set the rq to NULL any more or otherwise won't know which scheduler to use for the cleanup. Just remove the entity from the scheduling list instead.

The bo_list handle is allocated by OP_CREATE, so in OP_UPDATE here we just re-create the bo_list object and replace the handle. This way we don't need locking to protect the bo_list because it's always re-created when changed.
