* radeon_pm: fix oops in hwmon_attributes_visible() and ↵Sergey Senozhatsky2013-12-151-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | radeon_hwmon_show_temp_thresh() Since commit ec39f64bba34 ("drm/radeon/dpm: Convert to use devm_hwmon_register_with_groups") radeon_hwmon_init() is using hwmon_device_register_with_groups(), which sets `rdev' as a device private driver_data, while hwmon_attributes_visible() and radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the vmap() routine for the dma-buf, we first grab the pages and then try to allocate a temporary array to pass to the vmap(). However, the shrinker can and will reap any object that is unbound if the allocation for the array first fails. This includes the object which we are attempting to vmap(). The solution is to mark the object's pages as pinned whilst we try the allocation to prevent the use-after-free introduced by the potential shrinkage.

This is relatively simple as we can just keep the objects pinned for not just the relocation but until we are finished. One such example is the possibility of the context switch causing an eviction or hitting the shrinker in order to fit its object into the aperture.

The exynos_drm_crtc_dpms function waits for the completion of pended page flip events. However, preclose callback - this releases all unhandled page flip events - is called prior to the exynos_drm_crtc_dpms function call when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms to wait infiniately for the completion of the page flip events. This patch releases the unhandled page flip events at postclose instead of preclose so that exynos_drm_crtc_dpms function can be waked up. Changelog v2: - fix a memory leak when drm is closed. . it has a memory leak when a requeste page flip is handled after drm_events_release() is called and before drm_fb_release() is called. At this time, a drm_pending_event will not be freed. So also this chage releases the drm_pending_event at postclose(). And it calls drm_vblank_put() for pair if there is any unhandled page flip event. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

| * | | drm/tegra: Tightly bind RGB output to DCThierry Reding2013-12-031-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the association to a DC was done via the encoder's .crtc field. That has the disadvantage that when an encoder is detached from its CRTC, that field is set to NULL, leading to situations where it is impossible to access the DC registers required by the RGB output. However, the coupling between DC and RGB output is really fixed on Tegra. While they can be detached logically in DRM, the RGB output can rely on the DC's existence.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When upcasting a NULL CRTC object, propagate the NULL pointer instead of some invalid pointer. This allows subsequent code to check that the cast object is valid. Signed-off-by: Thierry Reding <treding@nvidia.com>
