2011-06-21Revert "drm/i915: Kill GTT mappings when moving from GTT domain"Eric Anholt
This reverts commit 4a684a4117abd756291969336af454e8a958802f. Userland has always been required to set the object's domain to GTT before using it through a GTT mapping, it's not something that the kernel is supposed to enforce. (The pagefault support is so that we can handle multiple mappings without userland having to pin across them, not so that userland can use GTT after GPU domains without telling the kernel). Fixes 19.2% +/- 0.8% (n=6) performance regression in cairo-gl firefox-talos-gfx on my T420 latop. Signed-off-by: Keith Packard <keithp@keithp.com>

2011-06-20drm/radeon/kms/atom: fix duallink on some early DCE3.2 cardsAlex Deucher
Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.

2011-06-16drm/radeon: workaround a hw bug on some radeon chipsets with all-0 EDIDs.Dave Airlie
Some RS690 chipsets seem to end up with floating connectors, either a DVI connector isn't actually populated, or an add-in HDMI card is available but not installed. In this case we seem to get a NULL byte response for each byte of the i2c transaction, so we detect this case and if we see it we don't do anymore DDC transactions on this connector.

2011-06-14drm: Compare only lower 32 bits of framebuffer map offsetsTormod Volden
Drivers using multiple framebuffers got broken by commit 41c2e75e60200a860a74b7c84a6375c105e7437f which ignored the framebuffer (or register) map offset when looking for existing maps. The rationale was that the kernel-userspace ABI is fixed at a 32-bit offset, so the real offsets could not always be handed over for comparison. Instead of ignoring the offset we will compare the lower 32 bit. Drivers using multiple framebuffers should just make sure that the lower 32 bit are different. The existing drivers in question are practically limited to 32-bit systems so that should be fine for them. It is assumed that current drivers always specify a correct framebuffer map offset, even if this offset was ignored since above commit. So this patch should not change anything for drivers using only one framebuffer. Drivers needing multiple framebuffers with 64-bit map offsets will need to cook up something, for instance keeping an ID in the lower bit which is to be aligned away when it comes to using the offset. All of above applies to _DRM_REGISTERS as well. Signed-off-by: Tormod Volden <debian.tormod@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-06-08drm/radeon/kms: fix for radeon on systems >4GB without hardware iommuDaniel Haid
On my x86_64 system with >4GB of ram and swiotlb instead of a hardware iommu (because I have a VIA chipset), the call to pci_set_dma_mask (see below) with 40bits returns an error. But it seems that the radeon driver is designed to have need_dma32 = true exactly if pci_set_dma_mask is called with 32 bits and false if it is called with 40 bits. I have read somewhere that the default are 32 bits. So if the call fails I suppose that need_dma32 should be set to true.
