2013-08-19drm: mark context support as a legacy subsystemDaniel Vetter3-36/+68
So after a lot of digging around in git histories it looks like this has only ever be used by dri1 render clients. Hence we can fully disable the entire thing for modesetting drivers and so greatly reduce the attack surface for potential exploits (or at least tools like trinity ...). Also add the drm_legacy prefix for functions which are called from common code. To further reduce the impact on common code also extract all the ctx release handling into a function (instead of only releasing individual handles) and make ctxbitmap_cleanup return void - it can never fail.

2013-08-18drm/i915: Invalidate TLBs for the rings after a resetChris Wilson2-0/+14
After any "soft gfx reset" we must manually invalidate the TLBs associated with each ring. Empirically, it seems that a suspend/resume or D3-D0 cycle count as a "soft reset". The symptom is that the hardware would fail to note the new address for its status page, and so it would continue to write the shadow registers and breadcrumbs into the old physical address (now used by something completely different, scary). Whereas the driver would read the new status page and never see any progress, it would appear that the GPU hung immediately upon resume.

If we get an error event really early in the driver setup sequence, which gen3 is especially prone to with various display GTT faults we Oops. So try to avoid this. Additionally with Haswell the transcoders are a separate bank of registers from the pipes (4 transcoders, 3 pipes). In event of an error, we want to be sure we have a complete and accurate picture of the machine state, so record all the transcoders in addition to all the active pipes.

2013-08-10drm/i915: Allow the GPU to cache stolen memoryChris Wilson1-3/+2
As a corollary to reviewing the interaction between LLC and our cache domains, the GPU PTE bits are independent of the CPU PAT bits. As such we can set the cache level on stolen memory based on how we wish the GPU to cache accesses to it. So we are free to set the same default cache levels as for normal bo, i.e. enable LLC cacheing by default where appropriate.

2013-08-10drm/i915: Update rules for writing through the LLC with the cpuChris Wilson4-29/+35
As mentioned in the previous commit, reads and writes from both the CPU and GPU go through the LLC. This gives us coherency between the CPU and GPU irrespective of the attribute settings either device sets. We can use to avoid having to clflush even uncached memory. Except for the scanout. The scanout resides within another functional block that does not use the LLC but reads directly from main memory. So in order to maintain coherency with the scanout, writes to uncached memory must be flushed. In order to optimize writes elsewhere, we start tracking whether an framebuffer is attached to an object. v2: Use pin_display tracking rather than fb_count (to ensure we flush cursors as well etc) and only force the clflush along explicit writes to the scanout paths (i.e. pin_to_display_plane and pwrite into scanout). v3: Force the flush after hitting the slowpath in pwrite, as after dropping the lock the object's cache domain may be invalidated.

2013-08-10drm/i915: Update rules for reading cache lines through the LLCChris Wilson1-8/+14
The LLC is a fun device. The cache is a distinct functional block within the SA that arbitrates access from both the CPU and GPU cores. As such all writes to memory land first in the LLC before further action is taken. For example, an uncached write from either the CPU or GPU will then proceed to memory and evict the cacheline from the LLC. This means that a read from the LLC always returns the correct information even if the PTE bit in the GPU differs from the PAT bit in the CPU. For the older snooping architecture on non-LLC, the fundamental principle still holds except that some coordination is required between the CPU and GPU to explicitly perform the snooping (which is handled by our request tracking). The upshot of this is that we know that we can issue a read from either LLC devices or snoopable memory and trust the contents of the cache - i.e. we can forgo a clflush before a read in these circumstances. Writing to memory from the CPU is a little more tricky as we have to consider that the scanout does not read from the CPU cache at all, but from main memory. So we have to currently treat all requests to write to uncached memory as having to be flushed to main memory for coherency with all consumers.
