[PATCH AUTOSEL 5.7 13/53] drm: mcde: Fix display initialization problem
by Sasha Levin 02 Jul '20

02 Jul '20

From: Linus Walleij <linus.walleij(a)linaro.org> [ Upstream commit b984b6d8b52372b98cce0a6ff6c2787f50665b87 ] The following bug appeared in the MCDE driver/display initialization during the recent merge window. First the place we call drm_fbdev_generic_setup() in the wrong place: this needs to be called AFTER calling drm_dev_register() else we get this splat: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at ../drivers/gpu/drm/drm_fb_helper.c:2198 drm_fbdev_generic_setup+… [View More]

[PATCH AUTOSEL 5.7 10/53] gpu: host1x: Detach driver on unregister
by Sasha Levin 02 Jul '20

02 Jul '20

From: Thierry Reding <treding(a)nvidia.com> [ Upstream commit d9a0a05bf8c76e6dc79230669a8b5d685b168c30 ] Currently when a host1x device driver is unregistered, it is not detached from the host1x controller, which means that the device will stay around and when the driver is registered again, it may bind to the old, stale device rather than the new one that was created from scratch upon driver registration. This in turn can cause various weird crashes within the driver core because it is … [View More]

[PATCH AUTOSEL 5.7 09/53] drm/tegra: hub: Do not enable orphaned window group
by Sasha Levin 02 Jul '20

02 Jul '20

From: Nicolin Chen <nicoleotsuka(a)gmail.com> [ Upstream commit ef4e417eb3ec7fe657928f10ac1d2154d8a5fb38 ] Though the unconditional enable/disable code is not a final solution, we don't want to run into a NULL pointer situation when window group doesn't link to its DC parent if the DC is disabled in Device Tree. So this patch simply adds a check to make sure that window group has a valid parent before running into tegra_windowgroup_enable/disable. Signed-off-by: Nicolin Chen <… [View More]

[PATCH AUTOSEL 5.7 08/53] gpu: host1x: Clean up debugfs in error handling path
by Sasha Levin 02 Jul '20

[PATCH AUTOSEL 5.7 07/53] drm/ttm: Fix dma_fence refcnt leak when adding move fence
by Sasha Levin 02 Jul '20

02 Jul '20

From: Xiyu Yang <xiyuyang19(a)fudan.edu.cn> [ Upstream commit 11425c4519e2c974a100fc984867046d905b9380 ] ttm_bo_add_move_fence() invokes dma_fence_get(), which returns a reference of the specified dma_fence object to "fence" with increased refcnt. When ttm_bo_add_move_fence() returns, local variable "fence" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling path of ttm_bo_add_move_fence(). When … [View More]
