FB read/write really doesn't need to access the actual VRAM, we can just use a scratch area. This is required for using atom displayport calls later. Signed-off-by: -

None of the in-tree drivers use user objects yet so this wasn't hitting us. Stanse found unreachable code in ttm_bo_add_ttm: http://decibel.fi.muni.cz/~xslaby/stanse/error.cgi?db=32&id=714#l238Reported-by:

Both radeon and nouveau can re-use this code so move it up a level so they can. However the hw interfaces for aux ch are different enough that the code to translate from mode, address, bytes to actual hw interfaces isn't generic, so move that code into the Intel driver. Signed-off-by: -

This is intended to be used by ttm-aware drivers to 1) Block clients to inactive masters when they try to validate buffers for GPU use. 2) Optionally block clients to the current master when there is thrashing due to GPU memory shortage. Used by the vmwgfx driver. Signed-off-by:

Add objects needed for user-space to maintain reference counts on ttm objects. This is used by the vmwgfx driver which allows user-space to maintain map-counts on dma buffers, lock-counts on the ttm lock and ref-counts on gpu surfaces, gpu contexts and dma buffer. Signed-off-by:

Again we try to put VRAM at 0, and it didn't work on this chipset, reports of corrupt RAM appeared on irc and bugzilla. Fix the vram location according to what the BIOS setup, I'm not 100% sure we don't need the same thing on rs690/rs780/rs880, we probably should do it there just in case as its what the DDX does.

This commit adds a ioctl and property to allow userspace to notify the kernel that a framebuffer has changed. Instead of snooping the command stream this allows finer grained tracking of which areas have changed. The primary user for this functionality is virtual hardware like the vmware svga device, but also Xen hardware likes to be notify. There is also real hardware like DisplayLink and DisplayPort that might take advantage of this ioctl. Signed-off-by:

The vmwgfx driver has a per master rw lock around TTM, to guarantee mutual exclusion when needed. This is typically when all evictable buffers are evicted due to 1) vt switch 2) master switch 3) suspend / resume. In the multi-master case, on master switch the new master takes the previously active master lock in write mode, and then evicts all buffers. Any clients to previous masters will then block on that lock when trying to validate a buffer. fbdev also acts as a virtual master wrt this. Signed-off-by:

The locking & protection of radeon object was somewhat messy. This patch completely rework it to now use ttm reserve as a protection for the radeon object structure member. It also shrink down the various radeon object structure by removing field which were redondant with the ttm information. Last it converts few simple functions to inline which should with performances. airlied: rebase on top of r600 and other changes. Signed-off-by:

We really don't need to process every irq that comes in, we only really want to do SW irq processing when we are actually waiting for a fence to pass. I'm not 100% sure this is race free esp on non-MSI systems so it needs some testing. Signed-off-by: -

This enables the use of interrupts on r6xx/r7xx hardware. Interrupts are implemented via a ring buffer. The GPU adds interrupts vectors to the ring and the host reads them off in the interrupt handler. The interrupt controller requires firmware like the CP. This firmware must be installed and accessble to the firmware loader for interrupts to function. MSIs don't seem to work on my RS780. They work fine on all my discrete cards. I'm not sure about other RS780s or RS880s. I've disabled MSIs on RS780 and RS880, but it would probably be worth checking on some other systems. v2 - fix some checkpatch.pl problems; re-read the disp int status reg if we restart the ih; v3 - remove the irq handler if r600_irq_init() fails; remove spinlock in r600_ih_ring_fini(); move ih rb overflow check to r600_get_ih_wptr(); move irq ack to separate function; Signed-off-by:
