If we want a contiguous mapping of a single page sized object, we can forgo using vmap() and just use a regular kmap().

I have instances where I want to use drm_malloc_ab() but with a custom gfp mask. And with those, where I want a temporary allocation, I want to try a high-order kmalloc() before using a vmalloc().

We now have two implementations for vmapping a whole object, one for dma-buf and one for the ringbuffer. If we couple the mapping into the obj->pages lifetime, then we can reuse an obj->mapping for both and at the same time couple it into the shrinker. There is a third vmapping routine in the cmdparser that maps only a range within the object, for the time being that is left alone, but will eventually use these routines in order to cache the mapping between invocations. v2: Mark the failable kmalloc() as __GFP_NOWARN (vsyrjala) v3: Call unpin_vmap from the right dmabuf unmapper v4: Rename vmap to map as we don't wish to imply the type of mapping involved, just that it contiguously maps the object into kernel space.

This reverts commit 1028b55b. It's broken: it makes ext4 return an error at an invalid point, causing the readdir wrappers to write the the position of the last successful directory entry into the position field, which means that the next readdir will now return that last successful entry _again_. You can only return fatal errors (that terminate the readdir directory walk) from within the filesystem readdir functions, the "normal" errors (that happen when the readdir buffer fills up, for example) happen in the iterorator where we know the position of the actual failing entry. I do have a very different patch that does the "signal_pending()" handling inside the iterator function where it is allowable, but while that one passes all the sanity checks, I screwed up something like four times while emailing it out, so I'm not going to commit it today. So my track record is not good enough, and the stars will have to align better before that one gets committed. And it would be good to get some review too, of course, since celestial alignments are always an iffy debugging model. IOW, let's just revert the commit that caused the problem for now.

That limits what the library can do, and we cannot reference uninitialized fields until later. Defer some of the initialization until right after the gpiolib is initialized in these (rare) cases. - As a consequence: do not use devm_* resources when allocating the states in the initial set-up of the gpiochip.

Only declare a missed interrupt if we find that the GPU is idle with waiters and a hangcheck interval has passed in which no new user interrupts have been raised. v2: Clear the stuck interrupt marker between successful batches Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: NMika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1460195877-20520-3-git-send-email-chris@chris-wilson.co.uk

In order to simplify future patches, extract the lazy_coherency optimisation our of the engine->get_seqno() vfunc into its own callback. v2: Rename the barrier to engine->irq_seqno_barrier to try and better reflect that the barrier is only required after the user interrupt before reading the seqno (to ensure that the seqno update lands in time as we do not have strict seqno-irq ordering on all platforms). Reviewed-by: Dave Gordon <david.s.gordon@intel.com> [#v2] v3: Comments for hangcheck paranoia. Mika wanted to keep the extra barrier inside the hangcheck, just in case. I can argue that it doesn't provide a barrier against anything, but the side-effects of applying the barrier may prevent a false declaration of a hung GPU.

In order to ensure seqno/irq coherency, we currently read a ring register. The mmio transaction following the interrupt delays the inspection of the seqno long enough for the MI_STORE_DWORD_IMM to update the CPU cache. However, it is only the memory timing that is important for the purposes of the delay, we do not need nor desire the extra forcewake. v3: Update commentary Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@intel.com> [v2] Link: http://patchwork.freedesktop.org/patch/msgid/1460195877-20520-1-git-send-email-chris@chris-wilson.co.uk

Currently for the case where there is enough space at the end of Ring buffer for accommodating only the base request, the wrapround is done immediately and as a result the base request gets added at the start of Ring buffer. But there may not be enough free space at the beginning to accommodate the base request, as before the wraparound, the wait was effectively done for the reserved_size free space from the start of Ring buffer. In such a case there is a potential of Ring buffer overflow, the instructions at the head of Ring (ACTHD) can get overwritten. Since the base request can fit in the remaining space, there is no need to wraparound immediately. The wraparound will anyway happen later when the reserved part starts getting used.
