Unsurprisingly the cursor C regiters are also at a weird offset on CHV. Add more pipe offsets to handle them. This also gets rid of most of the differences between the i9xx vs. ivb cursor code. We can unify the remaining code as well, but I'll leave that for another patch. Signed-off-by:

This workaround is listed for CHV, but not for BDW. However BSpec notes that on BDW CSunit clock gating is always disabled irrespective of the relevant bit in the GEN6_UGCTL1 registers. For CHV however, such text is not present in BSpec, so it seems safer to just set the bit. Reviewed-by:

BDW has the same requirement but the w/a database doens't list this w/a for BDW. Seems to be another one of those "stick a bunch of known workarounds into this bag and write something on the label" type of things. Reviewed-by:

This is the last piece of code which write state to the hardware in the ironalake ->crtc_mode_set callback. I think we could merge this with the pll->enable hook, but otoh the ordering requirements with the ldvs port are really tricky. Doing the FP0/1 writes up-front before we even prepare the lvds port (in the pre_pll_enable hook) like on i9xx seems safest. With this ilk+ platforms are now ready for runtime PM with DPMS. Since hsw/bdw also support runtime pm besides snb we need to first make the haswell code save before we can touch the core code. Reviewed-by:

Instead of every time it isn't active: We only need to do that when the pll is currently unused, i.e. when pll->refcount == 0. For paranoia add a warning for the ibx case where plls have a fixed mapping and hence should always be unused after the call to intel_put_shared_dpll. v2: Simplify control flow and use struct assignment instead of memcpy as suggested by Damien.

With this all hw writes are also gone from the ->crtc_mode_set hook on vlv. I wondered whether we should track more of the pll state in the pipe config, but otoh as long as we don't have shared plls that's not really useful - the cross-checking of the port clock should be sufficient. While at it also de-magic some of the pipe checks, this has been irking me since a long time. Whit this vlv is now ready for runtime PM on dpms. If we'd have runtime PM support in general ...

These two writes are the very last hw writes from the ->crtc_modeset_callback on pre-gen5 hardware. As usual vlv is a bit different, so this here is just warm-up. Reviewed-by:

Again the same story: This code just transform sw state from the pipe config into hardware state. And again we can't move the pll code, but this time around because the state isn't properly tracked in the pipe config. Reviewed-by:

Daniel Vetter authored
Again this code just transforms sw state from the pipe config into hardware state, so we can just move it around. Unfortunately again a few forward declarations since intel_display.c is becoming a bit of a mess. Note that both for i9xx and ironlake code the only things remaining in the ->crtc_mode_set hook is now the clock state computation and sharing code. That needs to be moved into the compute config stage so that we can catch impossible configurations earlier. Also note that some of the DPLL hw setup code is still run from within ->crtc_mode_set, namele the pll->mode_set callback. We need to move that first before we can do fancy things like enable runtime PM for dpms off. v2: Make it compile again after the rebase, bisectability issue reported by Wu Fengguang. Reviewed-by:

Now this really should be in the pipe config somewhere, but till now it isn't. We can at least move it up a bit next to all the other pll code since intel_dp_set_m_n really doesn't depend upon this. This is just prep work so that moving all the hw frobbing code from ->crtc_mode_set to ->crtc_enable is clean. v2: Do the same for haswell while at it, not just for ivb. Reviewed-by:

All these functions simply convert sw state as encoded in the pipe config or primary framebuffer into hardware state. So we can move them all into the crtc enable hook. Unfortunately this means a little bit of duplication between the i9xx and vlv functions, but since we already have highly refactored code I think this is acceptable. Also a pile of forward declarations unfortunately. Note also that the various <platform>_update_pll functions are still called from within the ->crtc_mode_set hook. Mostly they compute the clock state for the pipe config, but unfortunately there are some random register writes interspersed. Those need to be moved out first before we can enable runtime PM for DPMS. Reviewed-by:

Before the process killer is invoked, oom-notifiers are executed for one last try at recovering pages. We can hook into this callback to be sure that everything that can be is purged from our page lists, and to give a summary of how much memory is still pinned by the GPU in the case of an oom. This should be really valuable for debugging OOM issues. Note that the last-ditch effort call to shrink_all we've previously called from our normal shrinker when we could free as much as the vm demaned is moved into the oom notifier. Since the shrinker accounting races against bind/unbind operations we might have called shrink_all prematurely, which this approach with an oom notifier avoids.

We're using the reset domains bits for g4x on ilk. But on ilk those bits actually shifted by one bit. Fix it up so that we use the correct bits. We were actually always writing 0x2 to the reset domain bits, which is a reserved value. In practice it looks like the hardware ignores that value since nothing happens if I write that value when there's a 3D workload running. Writing the _correct_ render domain value actually makes the GPU stop. Signed-off-by:

Try to flush out dirty pages into the swapcache (and from there into the swapfile) when under memory pressure and forced to drop GEM objects from memory. In effect, this should just allow us to discard unused pages for memory reclaim and to start writeback earlier. v2: Hugh Dickins warned that explicitly starting writeback from shrink_slab was prone to deadlocks within shmemfs.

When the machine is under a lot of memory pressure and being stressed by multiple GPU threads, we quite often report fewer than shrinker->batch (i.e. SHRINK_BATCH) pages to be freed. This causes the shrink_control to skip calling into i915.ko to release pages, despite the GPU holding onto most of the physical pages in its active lists.

shmemfs first checks if there is enough memory to allocate the page and reports ENOSPC should there be insufficient, along with the usual ENOMEM for a genuine allocation failure. We use ENOSPC in our driver to mean that we have run out of aperture space and so want to translate the error from shmemfs back to our usual understanding of ENOMEM. None of the the other GEM users appear to distinguish between ENOMEM and ENOSPC in their error handling, hence it is easiest to do the fixup in i915.ko Cc: Hugh Dickins <hughd@google.com> Signed-off-by:

So far we used the wrong opcodes to access the DSI registers, so the register writes during DSI programming didn't actually succeed and left the registers unchanged. This wasn't a problem for the initial modeset, where the BIOS-programmed values happened to work, but after resuming from s0ix these registers are reset and failing to program them results in a blank screen.
