2016-11-27drm/msm: support multiple address spacesRob Clark
We can have various combinations of 64b and 32b address space, ie. 64b CPU but 32b display and gpu, or 64b CPU and GPU but 32b display. So best to decouple the device iova's from mmap offset. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-26drm/msm/mdp5: clip img size to src sizeRob Clark
If fb dimensions are larger than what can be scanned out, but the src dimensions are not, the hw can still handle this. So clip. Signed-off-by: Rob Clark <robdclark@gmail.com>

2016-11-26drm/msm/mdp5: no scaling support on RGBn pipes for 8x16Rob Clark

2016-11-26drm/msm/mdp5: handle non-fullscreen base plane caseRob Clark
If the bottom-most layer is not fullscreen, we need to use the BASE mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The blend_setup() code pretty much handled this already, we just had to figure this out in _atomic_check() and assign the stages appropriately. Also fix the case where there are zero enabled planes, where we also need to enable BORDER_OUT. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-25drm: hdlcd: Fix cleanup orderRobin Murphy
If hdlcd_drm_bind() fails at drm_fbdev_cma_init(), its cleanup will call drm_mode_config_cleanup() as if to balance drm_mode_config_reset(). The net result is that drm_connector_cleanup() will clean up the active connectors long before component_unbind_all() gets called, so when the connector later tries to clean up itself after being unbound, Bad Things can happen: [ 4.121888] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 4.129951] pgd = ffffff80091e0000 [ 4.133345] [00000000] *pgd=00000009ffffe003, *pud=00000009ffffe003, *pmd=0000000000000000 [ 4.141613] Internal error: Oops: 96000005 [#1] PREEMPT SMP [ 4.147144] Modules linked in: [ 4.150188] CPU: 0 PID: 122 Comm: kworker/u12:2 Not tainted 4.8.0-rc2+ #989 [ 4.157097] Hardware name: ARM Juno development board (r1) (DT) [ 4.162981] Workqueue: deferwq deferred_probe_work_func [ 4.168173] task: ffffffc975d93200 task.stack: ffffffc975dac000 [ 4.174055] PC is at drm_connector_cleanup+0x58/0x1c0 [ 4.179074] LR is at tda998x_unbind+0x24/0x40 [ 4.183401] pc : [<ffffff80084c46f0>] lr : [<ffffff800850414c>] pstate: 00000045 [ 4.190750] sp : ffffffc975dafa10 [ 4.194041] x29: ffffffc975dafa10 x28: ffffffc9768152a8 [ 4.199325] x27: ffffffc97ff46450 x26: ffffff8008d99000 [ 4.204608] x25: dead000000000100 x24: dead000000000200 [ 4.209891] x23: ffffffc976bf91e8 x22: 0000000000000000 [ 4.215172] x21: ffffffc976bf9170 x20: ffffffc976bf9170 [ 4.220454] x19: ffffffc976bf9018 x18: 0000000000000000 [ 4.225737] x17: 0000000074ce71ee x16: 000000008ff5d35f [ 4.231019] x15: ffffffc97681e91c x14: ffffffffffffffff [ 4.236301] x13: ffffffc97681e185 x12: 0000000000000038 [ 4.241583] x11: 0101010101010101 x10: 0000000000000000 [ 4.246866] x9 : 0000000040000000 x8 : 0000000000210d00 [ 4.252148] x7 : ffffffc97fea8c00 x6 : 000000000000001b [ 4.257430] x5 : ffffff80084b7b8c x4 : 0000000000000080 [ 4.262712] x3 : ffffff8008504128 x2 : ffffffc975df3800 [ 4.267993] x1 : 0000000000000000 x0 : 0000000000000000 ...

2016-11-23drm/amdgpu:impl vgt_flush for VI(V5)Monk Liu
when shadowing enabled, tesselation app will trigger vm fault because below three tesselation registers: VGT_TF_RING_SIZE__CI__VI, VGT_HS_OFFCHIP_PARAM__CI__VI, VGT_TF_MEMORY_BASE__CI__VI, need to be programed after vgt-flush. Tesselation picture vm fault disappeared after vgt-flush introduced. v2:implement vgt-flush for CI & SI. v3:move vgt flush inside of cntx_cntrl v4:count vgt flush in frame_size v5:squash in typo fix Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2016-11-23drm/radeon: fix power state when port pm is unavailable (v2)Peter Wu
When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue. v2: agd: fix typo Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98505 Signed-off-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: <stable@vger.kernel.org> # 4.8+ Reviewed-by: Alex Deucher <alexander.deucher@amd.com>

2016-11-22drm/arm: hdlcd: fix plane base address updateRussell King
While testing HDMI with Xorg on the Juno board, I find that when Xorg starts up or shuts down, the display is shifted significantly to the right and wrapped in the active region. (No sync bars are visible.) The timings are correct, it behaves as if the start address has been shifted many pixels _into_ the framebuffer. This occurs whenever the display mode size is changed - using xrandr in Xorg shows that changing the resolution triggers the problem almost every time, but changing the refresh rate does not. Using devmem2 to disable and re-enable the HDLCD resolves the issue, and repeated disable/enable cycles do not make the issue re-appear. Further debugging shows that we try to update the controller configuration while enabled. Alwys ensure that the HDLCD is disabled prior to updating the controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on() so that DRM knows whether it can expect vblank interrupts.

2016-11-22drm/atomic: Unconfuse the old_state mess in commmit_tailDaniel Vetter
I totally butcherd the job on typing the kernel-doc for these, and no one realized. Noticed by Russell. Maarten has a more complete approach to this confusion, by making it more explicit what the new/old state is, instead of this magic switching behaviour. v2: - Liviu pointed out that wait_for_fences is even more magic. Leave that as @state, and document @pre_swap better. - While at it, patch in header for the reference section. - Fix spelling issues Russell noticed. v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/, since async flip is something else than non-blocking.
