2011-02-07drm/i810: remove the BKLArnd Bergmann
SMP i810 systems were practically nonexistent and the configuration was not officially supported by Intel at the time when Pentium-III was common. With this change, it is still possible to build a distribution kernel that has support for SMP and includes the i810 driver without the BKL. As a precaution, check for the theoretical SMP case at run time and refuse to load the driver. We also need to disable CONFIG_PREEMPT builds for this driver.

2011-01-31drm/i915: Suppress spurious vblank interruptsChris Wilson
Hugh Dickins found that characters in xterm were going missing and oft delayed. Being the curious type, he managed to associate this with the new high-precision vblank patches; disabling these he found, restored the orderliness of his characters. The oddness begins when one realised that Hugh was not using vblanks at all on his system (fvwm and some xterms). Instead, all he had to go on were warning of a pipe underrun, curiously enough at around 60Hz. He poked and found that in addition to the underrun warning, the hardware was flagging the start of a new frame, a vblank, which in turn was kicking off the pending vblank processing code. There is little we can do for the underruns on Hugh's machine, a Crestline [965GM], which must have its FIFO watermarks set to 8. However, we do not need to process the vblank if we know that they are disabled... Reported-by: Hugh Dickins <hughd@google.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-01-31drm: Simplify and defend later checks when disabling a crtcChris Wilson
By setting the FB of a CRTC to NULL, we are turning off the CRTC (and so disable the unused encoders and connectors). As such we can simplify the later tests by making sure the set->mode is NULL. Setting the num_connectors to zero means that we do not need to loop over the unused connectors. All current usage appears correct, this only builds additional defense into the routine.

2011-01-31drm: Don't switch fb when disabling an outputChris Wilson
In drm_crtc_helper_set_config, we call drm_crtc_helper_set_mode which may return early and do no operation if the crtc is to be disabled. In this case we merrily swap to the new fb, discarding the old_fb believing that it has been cleaned up. However, due to the early return, the old_fb was not presented to the backend for correct reaping, and nor was the new one - which is about to be reaped via the drm_helper_disable_unused_functions(), leading to incorrect refcounting of the pinned objects.

We pass in the array of ttm pages to be populated in the GART/MM of the card (or AGP). Patch titled: "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set." uses the DMA API to make those pages have a proper DMA addresses (in the situation where page_to_phys or virt_to_phys do not give use the DMA (bus) address). Since we are using the DMA API on those pages, we should pass in the DMA address to this function so it can save it in its proper fields (later patches use it).

2011-01-27ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set.Konrad Rzeszutek Wilk
For pages that have the TTM_PAGE_FLAG_DMA32 flag set we use the DMA API. We save the bus address in our array which we use to program the GART (see "radeon/ttm/PCIe: Use dma_addr if TTM has set it." and "nouveau/ttm/PCIe: Use dma_addr if TTM has set it."). The reason behind using the DMA API is that under Xen we would end up programming the GART with the bounce buffer (SWIOTLB) DMA address instead of the physical DMA address of the TTM page. The reason being that alloc_page with GFP_DMA32 does not allocate pages under the the 4GB mark when running under Xen hypervisor. Under baremetal this means we do the DMA API call earlier instead of when we program the GART.
