| | | | | | | | | | | | | | | | | | | | | | If enabled, during initialization BO GTT->VRAM and VRAM->GTT GPU copies are tested across the whole GTT aperture. This has helped uncover the benchmark copy size bug and verify the maximum aperture size supported by the AGP bridge in my PowerBook.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | attributes. For x86 this affected highmem pages only, since they were always kmapped cache-coherent, and this is fixed using kmap_atomic_prot(). For other architectures that may not modify the linear kernel map we resort to vmap() for now, since kmap_atomic_prot() generally uses the linear kernel map for lowmem pages. This of course comes with a performance impact and should be optimized when possible. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| * drm/radeon/kms: vram sizing on certain r100 chips needs workaround.Dave Airlie2009-07-29
| | | | | | | | | | | | | | | | | | | | | | If an rn50/r100/m6/m7 GPU has < 64MB RAM, i.e. 8/16/32, the aperture used to calculate the MC_FB_LOCATION needs to be worked out from the CONFIG_APER_SIZE register, and not the actual vram size. TTM VRAM size was also being initialised wrong, use actual vram size to initialise it. Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon: Pay more attention to object placement requested by userspace.Michel Dänzer2009-07-29
| | | | | | | | | | | | | | | | Previously we were basically always setting the GTT and VRAM flags regardless of what userspace requested. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon: Fall back to evicting BOs with memcpy if necessary.Michel Dänzer2009-07-29
| | | | | | | | | | | | | | | | Otherwise if there's no GTT space we would fail the eviction, leading to cascaded failure. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon: Don't unreserve twice on failure to validate.Michel Dänzer2009-07-29
| | | | | | | | | | | | | | | | This is done later in radeon_object_list_unvalidate(). Doing it twice triggers a BUG in TTM, rendering X on KMS unusable until reboot. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds new set/get tiling interfaces where the pitch and macro/micro tiling enables can be set. Along with a flag to decide if this object should have a surface when mapped. The only thing we need to allocate with a mapped surface should be the frontbuffer. Note rotate scanout shouldn't require one, and back/depth shouldn't either, though mesa needs some fixes. It fixes the TTM interfaces along Thomas's suggestions, and I've tested the surface stealing code with two X servers and not seen any lockdep issues. I've stopped tiling the fbcon frontbuffer, as I don't see there being any advantage other than testing, I've left the testing commands in there, just flip the fb_tiled to true in radeon_fb.c Open: Can we integrate endian swapping in with this? Future features: texture tiling - need to relocate texture registers TXOFFSET* with tiling info. This also merges Michel's cleanup surfaces regs at init time patch even though it makes sense on its own, this patch really relies on it.

| | | | | | | | | | | | | | | | | | | | Allows us to hit dot clocks much closer, especially on chips with non-27 Mhz reference clocks like most IGP chips.

| * drm/radeon/kms: fix quirk for MSI laptopAlex Deucher2009-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | The line mux for the connector in the bios tables is used for enumerating drm connectors. Since this laptop has a quirk where the same line much is listed for both VGA and LVDS, the connectors get combined. Setting the line mux on LVDS to an unused value prevents both encoders from being combined into the same connector. This should fix bko bug 13720.

| * drm/radeon: fix support for vline relocations.Dave Airlie2009-07-15
| | | | | | | | | | | | | | | | | | | | | | | | Userspace sends us a special relocation type to sync video/exa to vlines to avoid tearing, this deals with the relocation in the kernel, it picks the correct crtc and avoids issues where crtcs are disabled. This version also parses the wait until to make sure it isn't trying to do anything evil. Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon/kms: respect TOM on rs100->rs480 IGP variants.Dave Airlie2009-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Normally we are free to place VRAM where we want in the GPUs memory address space, however on IGP chips the VRAM is actual RAM, and no special translation or aperture is used inside the GPU MC. So when you move the VRAM aperture away from the TOM register, you actually move it into main memory and can trash things quite badly. This commit makes the code respect the TOM location for MC_FB_LOCATION. Signed-off-by: Dave Airlie <airlied@redhat.com>

* | drm/i915: Disable GEM when a broken video BIOS takes up the whole aperture.Eric Anholt2009-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is seen on some G41 systems, where the BIOS will consume all but a few KB of the aperture. This should be bad for all operating systems, as it means that the OS can't dynamically manage memory between graphics and the rest of the system, and OSes that did static memory management statically add memory in addition to the BIOS allocation anyway. So, instead of working around it, just fail out verbosely. fd.o bug #21574 Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some boxes the mobile chipset is used and there is no LVDS device. In such case we had better not initialize the LVDS output device so that one pipe can be used for other output device. For example: E-TOP. But unfortunately the LVDS device is still initialized on the boxes based on mobile chipset in KMS mode. It brings that this pipe occupied by LVDS can't be used for other output device. After checking the acpidump we find that there is no LID device on such boxes. In such case we can use the LID device to decide whether the LVDS device should be initialized. If there is no LID device, we can think that there is no LVDS device. It is unnecessary to initialize the LVDS output device. If there exists the LID device, it will continue the current flowchart. Maybe on some boxes there is no LVDS device but the LID device is found. In such case it should be added to the quirk list. http://bugs.freedesktop.org/show_bug.cgi?id=21496 http://bugs.freedesktop.org/show_bug.cgi?id=21856 http://bugs.freedesktop.org/show_bug.cgi?id=21127 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> [anholt: squashed in style fixups] Signed-off-by: Eric Anholt <eric@anholt.net>
