Merge branch 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip into drm-fixes Here are some fixes for drm/rockchip, these fixes base on drm-next. These fixes works on my popmetal(rk3288) board. About patch: drm/atomic-helper: Export framebuffer_changed() Daniel Vetter ack for merging it through rockchip git trees, so framebuffer_changed() can be reused by drm/rockchip. All others looks good, so I'd like you can land them. * 'drm-rockchip-next-fixes-2016-01-22' of https://github.com/markyzq/kernel-drm-rockchip: drm/rockchip: respect CONFIG_DRM_FBDEV_EMULATION drm/rockchip: fix wrong pitch/size using on gem drm/rockchip: explain why we can't wait_for_vblanks drm/rockchip: don't wait for vblank if fb hasn't changed drm/atomic-helper: Export framebuffer_changed() drm/rockchip/dsi: fix handling mipi_dsi_pixel_format_to_bpp result drm/rockchip: vop: fix mask when updating interrupts drm/rockchip: cleanup unnecessary export symbol drm/rockchip: Don't build rockchip_drm_vop as modules

A bunch of etnaviv fixes for 4.5-rc. Most of them are fixing things in code paths that will only be hit if something goes wrong, which have been unearthed by more extensive testing. The only thing that doesn't really qualify as fixes is an UAPI extension that userspace wants to rely on being present, so I want to fast-track this into 4.5 before etnaviv ends up in a released kernel. * 'drm-etnaviv-fixes' of git://git.pengutronix.de/git/lst/linux: drm/etnaviv: call correct function when trying to vmap a DMABUF drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmap drm/etnaviv: fix get pages error path in etnaviv_gem_vaddr drm/etnaviv: fix memory leak in IOMMU init path drm/etnaviv: add further minor features and varyings count drm/etnaviv: add helper for comparing model/revision IDs drm/etnaviv: add helper to extract bitfields drm/etnaviv: use defined constants for the chip model drm/etnaviv: update common and state_hi xml.h files drm/etnaviv: ignore VG GPUs with FE2.0 drm/etnaviv: fix failure path if model is zero drm/etnaviv: hold object lock while getting pages for coredump drm/etnaviv: remove owner assignment from platform_driver

This fixes a race condition in the error case: since the pt bos have not necessarily been reserved in case of an error, we could move a pt bo that is currently in the middle of being evicted/moved by another process, which then resulted in a BUG_ON in ttm_bo_add_to_lru.

When trying to get the vmap address of an imported buffer, we must call into the appropriate helper function, to allow the exporter to establish the vmap, instead of trying to vmap the buffer on our own. Add an indirection through etnaviv_gem_ops to allow the correct implementation to be called. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

In case that etnaviv_gem_get_pages is unable to get the required pages the object mutex needs to be unlocked. Also return NULL in this case instead of propagating the error, as callers of this function might not be prepared to handle a pointer error, but expect this call to follow the semantics of a plain vmap to return NULL in case of an error.

Don't init fbdev if we don't have connectors.

This fixes an issue that was noticed on an optimus/prime laptop with a kernel that was old enough to not support the integrated intel gfx (which was driving all the outputs), but did have support for the discrete radeon gpu. The end result was not falling back to VESA and leaving the user with a black screen. (Plus it is kind of silly to create an framebuffer device if there are no outputs hooked up to the gpu.)

If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent.
