Daniel Vetter wrote First pull request for 3.5-next, slightly large than usual because new things kept coming in since the last pull for 3.4. Highlights: - first batch of hw enablement for vlv (Jesse et al) and hsw (Eugeni). pci ids are not yet added, and there's still quite a few patches to merge (mostly modesetting). To make QA easier I've decided to merge this stuff in pieces. - loads of cleanups and prep patches spurred by the above. Especially vlv is a real frankenstein chip, but also hsw is stretching our driver's code design. Expect more to come in this area for 3.5. - more gmbus fixes, cleanups and improvements by Daniel Kurtz. Again, there are more patches needed (and some already queued up), but I wanted to split this a bit for better testing. - pwrite/pread rework and retuning. This series has been in the works for a few months already and a lot of i-g-t tests have been created for it. Now it's finally ready to be merged. Note that one patch in this series touches include/pagemap.h, that patch is acked-by akpm. - reduce mappable pressure and relocation throughput improvements from Chris. - mmap offset exhaustion mitigation by Chris Wilson. - a start at figuring out which codepaths in our messy dri1/ums+gem/kms driver we actually need to support by bailing out of unsupported case. The driver now refuses to load without kms on gen6+ and disallows a few ioctls that userspace never used in certain cases. More of this will definitely come. - More decoupling of global gtt and ppgtt. - Improved dual-link lvds detection by Takashi Iwai. - Shut up the compiler + plus fix the fallout (Ben) - Inverted panel brightness handling (mostly Acer manages to break things in this way). - Small fixlets and adjustements and some minor things to help debugging. Regression-wise QA reported quite a few issues on ivb, but all of them turned out to be hw stability issues which are already fixed in drm-intel-fixes (QA runs the nightly regression tests on -next alone, without -fixes automatically merged in). There's still one issue open on snb, it looks like occlusion query writes are not quite as cache coherent as we've expected. With some of the pwrite adjustements we can now reliably hit this. Kernel workaround for it is in the works." * 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel: (101 commits) drm/i915: VCS is not the last ring drm/i915: Add a dual link lvds quirk for MacBook Pro 8,2 drm/i915: make quirks more verbose drm/i915: dump the DMA fetch addr register on pre-gen6 drm/i915/sdvo: Include YRPB as an additional TV output type drm/i915: disallow gem init ioctl on ilk drm/i915: refuse to load on gen6+ without kms drm/i915: extract gt interrupt handler drm/i915: use render gen to switch ring irq functions drm/i915: rip out old HWSTAM missed irq WA for vlv drm/i915: open code gen6+ ring irqs drm/i915: ring irq cleanups drm/i915: add SFUSE_STRAP registers for digital port detection drm/i915: add WM_LINETIME registers drm/i915: add WRPLL clocks drm/i915: add LCPLL control registers drm/i915: add SSC offsets for SBI access drm/i915: add port clock selection support for HSW drm/i915: add S PLL control drm/i915: add PIXCLK_GATE register ...

On coherent systems (not-AGP) the IB should be in cached memory so should be just as fast, so we can avoid copying to temporary pages and just use it directly. provides minor speedups on rv530: gears ~1820->1860, ipers: 29.9->30.6, but always good to use less CPU if we can. v3: cleanup unneeded bits.

Ums is already disabled, but on ilk we can additionally disable gem initialization when using user mode setting. Upstream never support ilk without kernel modesetting and not even the RHEL ilk ums backport needs gem - that driver is based on xf86-video-intel version 2.2, which is pre-gem. Reviewed-by:

Spurred by an irc discussion, let's start to clear up which parts of our kms + ums/gem + ums/dri1 + vbios/dri1 kernel driver pieces userspace in the wild actually uses. The idea is that we introduce checks at entry-points (module load time, ioctls, ...) first and then reap any obviously dead code in a second step. As a first step refuse to load without kms on chips where userspace never supported ums. Now upstream hasn't supported ums on ilk, ever. But RHEL had the great idea to backport the kms support to their ums driver. Cc: Dave Airlie <airlied@gmail.com> Signed-Off-by: -

vlv, ivb and snb all share the gen6+ gt irq handling. 3 copies of the same stuff is a bit much, so extract it into a little helper. Now ilk has a different gt irq handling than snb, but shares the same irq handler (due to the similar display block). So also extract the ilk gt irq handling to clearly separate these two things. Nice side effect of this is that we can complete Ben Widawsky's gen6+ irq bit #define cleanup and call the render irq also with the GEN6 alias. Beforehand that code was shared with ilk, and neither option really made much sense. As a bonus this enables the error interrupt handling lifted from the vlv code on snb and ivb, too. Reviewed-by:

Top-level interrupt bits are usually found in the display block. It therefore makes sense to use HAS_PCH_SPLIT in i915_irq.c But the irq stuff in intel_ring.c only concerns itself with render core/gt-level interrupt sources. It therefore makes more sense to switch based on gpu gen. Kills a vlv special case. Reviewed-by:

This got copy-pasted from an older version. The newer kinds of workarounds don't need this anymore. Shame on me for not noticing when picking up the vlv irq patch. Reviewed-by:

We can now open-code the get/put irq functions as they were just abstracting single register definitions. It would be nice to merge this in with the IRQ handling code... but that is too much work for me at present. In addition I could probably collapse this in to a lot of the Ironlake stuff, but I don't think it's worth the potential regressions. This patch itself should not effect functionality.

- gen6 put/get only need one argument rflags and gflags are always the same (see above explanation) - remove a couple redundantly defined IRQs - reordered some lines to make things go in descending order Every ring has its own interrupts, enables, masks, and status bits that are fed into the main interrupt enable/mask/status registers. At one point in time it seemed like a good idea to make our functions support the notion that each interrupt may have a different bit position in the corresponding register (blitter parser error may be bit n in IMR, but bit m in blitter IMR). It turned out though that the HW designers did us a solid on Gen6+ and this unfortunate situation has been avoided. This allows our interrupt code to be cleaned up a bit. I jammed this into one commit because there should be no functional change with this commit, and staging it into multiple commits was unnecessarily artificial IMO.
