[Why] Some boards seem to have a problem where HPD is high on HDMI even though no display is connected. We don't want to report these as connected. DP spec still requires us to report DP displays as connected when HPD is high but we can't read the EDID in order to go to fail-safe mode. [How] If connector_signal is not DP abort detection if we can't retrieve the EDID. v2: Add Bugzilla and stable Bugzilla: https://bugs.freedesktop.org/107390 Bugzilla: https://bugs.freedesktop.org/106846 Cc: stable@vger.kernel.org Signed-off-by:

idx can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state() warn: potential spectre issue 'data.states' Fix this by sanitizing idx before using it to index data.states Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:

Every set_pages_array_wb call resulted in cross-core interrupts and TLB flushes. Merge more of them for less overhead. This reduces the time needed to free a 1.6 GiB GTT WC buffer as part of Vulkan CTS from ~2 sec to < 0.25 sec. (Allocation still takes more than 2 sec though) (v2): use set_pages_wb instead of set_memory_wb. Signed-off-by:
