2018-01-10drm/vmwgfx: Potential off by one in vmw_view_add()Dan Carpenter1-0/+2
The vmw_view_cmd_to_type() function returns vmw_view_max (3) on error. It's one element beyond the end of the vmw_view_cotables[] table. My read on this is that it's possible to hit this failure. header->id comes from vmw_cmd_check() and it's a user controlled number between 1040 and 1225 so we can hit that error. But I don't have the hardware to test this code.

2018-01-10drm/tegra: sor: Fix hang on Tegra124 eDPThierry Reding1-0/+3
The SOR0 found on Tegra124 and Tegra210 only supports eDP and LVDS and therefore has a slightly different clock tree than the SOR1 which does not support eDP, but HDMI and DP instead. Commit e1335e2f0cfc ("drm/tegra: sor: Reimplement pad clock") breaks setups with eDP because the sor->clk_out clock is uninitialized and therefore setting the parent clock (either the safe clock or either of the display PLLs) fails, which can cause hangs later on since there is no clock driving the module. Fix this by falling back to the module clock for sor->clk_out on those setups. This guarantees that the module will always be clocked by an enabled clock and hence prevents those hangs.

2018-01-09drm/vmwgfx: Don't cache framebuffer mapsThomas Hellstrom3-36/+13
Buffer objects need to be either pinned or reserved while a map is active, that's not the case here, so avoid caching the framebuffer map. This will cause increasing mapping activity mainly when we don't do page flipping. This fixes occasional garbage filled screens when the framebuffer has been evicted after the map. Since in-kernel mapping of whole buffer objects is error-prone on 32-bit architectures and also quite inefficient, we will revisit this later.

Commit ebae8d07435a ("drm/tegra: dc: Implement legacy blending") broke support for YUV overlays by accident. The reason is that YUV formats are considered opaque because they have no alpha component, but on the other hand no corresponding format with an alpha component can be returned. In the case of YUV formats, the opaque format is the same as the alpha format, so add the special case to restore YUV overlay support.

git://git.armlinux.org.uk/~rmk/linux-arm into drm-next This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.
