When the caller maps their dmabuf and we return an sg_table, the caller doesn't expect the pages beneath that sg_table to vanish on a whim (i.e. under mempressure). The contract is that the pages are pinned for the duration of the mapping (from dma_buf_map_attachment() to dma_buf_unmap_attachment). To comply, we need to introduce our own vgem_object.pages_pin_count and elevate it across the mapping. However, the drm_prime interface we use calls drv->prime_pin on dma_buf_attach and drv->prime_unpin on dma_buf_detach, which while that does cover the mapping is much broader than is desired -- but it will do for now. v2: also hold the pin across prime_vmap/vunmap Reported-by:

Both drivers shut down all crtc beforehand already, which will shut up any pending vblank (the only thing vblank_cleanup really does is disable the disable timer). Hence we don't need this here and can remove it. Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Acked-by:

For RK3399's GRF module, if we want to operate the graphic related grf registers, we need to enable the pclk_vio_grf which supply power for VIO GRF IOs, so it's better to introduce an optional grf clock in driver. Signed-off-by:

For RK3399 HDMI, there is an external clock need for HDMI PHY, and it should keep the same clock rate with VOP DCLK. VPLL have supported the clock for HDMI PHY, but there is no clock divider bewteen VPLL and HDMI PHY. So we need to set the VPLL rate manually in HDMI driver. Signed-off-by:

This way drm_atomic_helper_wait_for_fences() will actually do something. The vc4_seqno_cb has been doing the fence waits on V3D manually, so far. Signed-off-by:

With instantaneous high precision vblank timestamping that updates at leading edge of vblank, the emulated "hw vblank counter" from vblank timestamping which increments at leading edge of vblank, and reliable page flip execution and completion at leading edge of vblank, we should meet the requirements for fast vblank irq disable/enable. Testing against rpi-4.12-rc5 Linux kernel with timing measurement equipment indicates this works fine, so allow immediate vblank disable for power saving. For debugging in case of unexpected trouble, booting with kernel cmdline option drm.vblankoffdelay=0 would keep vblank irqs on to approximate old behavior. v2: Respin onto drm-misc-next, per Eric's suggestion. Drop !vc4->firmware_kms check, as the firmware_kms implementation does not exist in upstream. Signed-off-by:Mario Kleiner <mario.kleiner.de@gmail.com> Cc: Eric Anholt <eric@anholt.net> Reviewed-by:

Now that we have a callback to check if crtc supports a given mode we can use it in arcpgu so that we restrict the number of probbed modes to the ones we can actually display. This is specially useful because arcpgu crtc is responsible to set a clock value in the commit() stage but unfortunatelly this clock does not support all the needed ranges. Also, remove the atomic_check() callback as mode_valid() callback will be called before. Signed-off-by:

VBLANK events are missed when the CRTC is being disabled because the driver does not wait till the end of the frame before stopping the HVS and PV blocks. In this case, we should explicitly issue a VBLANK event if there's one waiting. Signed-off-by:

Since commit ca8e2ad7 Author: Thierry Reding <treding@nvidia.com> Date: Fri Apr 11 15:23:00 2014 +0200 drm: Introduce drm_dev_set_unique() the ->set_busid callback is optional. On top of that the udl one isn't really fully compliant with the drm uabi, but since only modesetting ever binds to it (there's no 3d accel on udl) it doesn't matter. Still, can't harm to aling and use the default used by everyone else. Acked-by:

Unify and review everything, plus make sure it's all correct markup. Drop the kernel-doc for internal functions. Also rework the overview section, it's become rather outdated. Unfortuantely the kernel-doc in drm_driver isn't rendered yet, but that will change as soon as drm_driver is kernel-docified properly. Also document properly that drm_vblank_cleanup is optional, the core calls this already. v2: Make it clear that cleanup happens in drm_dev_fini for drivers with their own ->release callback (Thierry).
