2016-08-02drm/i915: cleanup_plane_fb: also drop reference to current state wait_reqKeith Packard1-0/+2
There are two paths into intel_cleanup_plane_fb, the normal completion path and the failure path. In the failure case, intel_cleanup_plane_fb is called before drm_atomic_helper_swap_state, so any wait_req reference made in intel_prepare_plane_fb will be in old_intel_state->wait_req. In the normal completion path, drm_atomic_helper_swap_state has already been called, so the plane state holding the just-used wait_req will not be in old_intel_state->wait_req, rather it will be in the state associated with the plane itself. Clearing this reference ensures that the wait_req will be freed as soon as it the related mode setting operation is complete, rather than waiting for some future mode setting operation to eventually dereference it. The existing dereference of old_intel_state->wait_req is still required as that will hold the wait_req when the mode setting operation fails. cc: Daniel Vetter <daniel.vetter@intel.com> cc: David Airlie <airlied@linux.ie> cc: intel-gfx@lists.freedesktop.org cc: dri-devel@lists.freedesktop.org Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

According to Bspec FW_BLC_SELF exists on 915G also. Let's program it. The only open question is whether there's is a memory self-refresh enable bit somewhere as well. For 945G/GM it's in FW_BLC_SELF, for 915GM it's in INSTPM. For 915G I can't find one in the docs. Let's drop a FIXME about this, in case someone with the hardware is ever bored enough to look for it.

2016-07-30drm/nouveau/acpi: fix lockup with PCIe runtime PMPeter Wu1-4/+31
Since "PCI: Add runtime PM support for PCIe ports", the parent PCIe port can be runtime-suspended which disables power resources via ACPI. This is incompatible with DSM, resulting in a GPU device which is still in D3 and locks up the kernel on resume (on a Clevo P651RA, GTX965M). Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi debugger trace) and stop using the DSM functions for D3cold when power resources are available on the parent PCIe port. pci_d3cold_disable() is not used because on some machines, the old DSM method is broken. On a Lenovo T440p (GT 730M) memory and disk corruption would occur, but that is fixed with this patch[2].

2016-07-30drm/nouveau/fbcon: fix font width not divisible by 8Mikulas Patocka3-4/+4
The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459d925 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459d925 was backported.
