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:Daniel Vetter <daniel.vetter@ffwll.ch>

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.
