On the load error path we can't have pending vblank interrupts, and on unload we already call drm_atomic_helper_shutdown beforehand! So all good to nuke it. Reviewed-by:

Again we probably want a drm_atomic_helper_shutdown somewhere, but that's a bit more analysis. Cc: Xinliang Liu <z.liuxinliang@hisilicon.com> Cc: Rongrong Zou <zourongrong@gmail.com> Cc: Xinwei Kong <kong.kongxinwei@hisilicon.com> Cc: Chen Feng <puck.chen@hisilicon.com> Reviewed-by:

So this seems to be the first driver that does it the right way round, so fix it up by calling drm_atomic_helper_shutdown instead. We need to do that before the last kms user is gone (fbdev emulation), but before we start shutting down hw stuff like interrupts.

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).

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:

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:
