2012-04-28drm/i915: Set the Stencil Cache eviction policy to non-LRA mode.Kenneth Graunke
Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when using separate stencil buffers. Without it, the GPU tries to use the LRA eviction policy, which isn't supported. This was supposed to be off by default, but seems to be on for many machines. This cannot be done in gen6_init_clock_gating with most of the other workaround bits; the render ring needs to exist. Otherwise, the register write gets dropped on the floor (one printk will show it changed, but a second printk immediately following shows the value reverts to the old one).

2012-04-26drm/i915: handle input/output sdvo timings separately in mode_setDaniel Vetter
We seem to have a decent confusion between the output timings and the input timings of the sdvo encoder. If I understand the code correctly, we use the original mode unchanged for the output timings, safe for the lvds case. And we should use the adjusted mode for input timings. Clarify the situation by adding an explicit output_dtd to the sdvo mode_set function and streamline the code-flow by moving the input and output mode setting in the sdvo encode together. Furthermore testing showed that the sdvo input timing needs the unadjusted dotclock, the sdvo chip will automatically compute the required pixel multiplier to get a dotclock above 100 MHz. Fix this up when converting a drm mode to an sdvo dtd. This regression was introduced in commit c74696b9c890074c1e1ee3d7496fc71eb3680ced Author: Pavel Roskin <proski@gnu.org> Date: Thu Sep 2 14:46:34 2010 -0400 i915: revert some checks added by commit 32aad86f particularly the following hunk: diff --git a/drivers/gpu/drm/i915/intel_sdvo.c b/drivers/gpu/drm/i915/intel_sdvo.c index 093e914..62d22ae 100644 --- a/drivers/gpu/drm/i915/intel_sdvo.c +++ b/drivers/gpu/drm/i915/intel_sdvo.c @@ -1122,11 +1123,9 @@ static void intel_sdvo_mode_set(struct drm_encoder *encoder, /* We have tried to get input timing in mode_fixup, and filled into adjusted_mode */ - if (intel_sdvo->is_tv || intel_sdvo->is_lvds) { - intel_sdvo_get_dtd_from_mode(&input_dtd, adjusted_mode); + intel_sdvo_get_dtd_from_mode(&input_dtd, adjusted_mode); + if (intel_sdvo->is_tv || intel_sdvo->is_lvds) input_dtd.part2.sdvo_flags = intel_sdvo->sdvo_flags; - } else - intel_sdvo_get_dtd_from_mode(&input_dtd, mode); /* If it's a TV, we already set the output timing in mode_fixup. * Otherwise, the output timing is equal to the input timing. Due to questions raised in review, below a more elaborate analysis of the bug at hand: Sdvo seems to have two timings, one is the output timing which will be sent over whatever is connected on the other side of the sdvo chip (panel, hdmi screen, tv), the other is the input timing which will be generated by the gmch pipe. It looks like sdvo is expected to scale between the two. To make things slightly more complicated, we have a bunch of special cases: - For lvds panel we always use a fixed output timing, namely intel_sdvo->sdvo_lvds_fixed_mode, hence that special case. - Sdvo has an interface to generate a preferred input timing for a given output timing. This is the confusing thing that I've tried to clear up with the follow-on patches. - A special requirement is that the input pixel clock needs to be between 100MHz and 200MHz (likely to keep it within the electromechanical design range of PCIe), 270MHz on later gen4+. Lower pixel clocks are doubled/quadrupled. The thing this patch tries to fix is that the pipe needs to be explicitly instructed to double/quadruple the pixels and needs the correspondingly higher pixel clock, whereas the sdvo adaptor seems to do that itself and needs the unadjusted pixel clock. For the sdvo encode side we already set the pixel mutliplier with a different command (0x21). This patch tries to fix this mess by: - Keeping the output mode timing in the unadjusted plain mode, safe for the lvds case. - Storing the input timing in the adjusted_mode with the adjusted pixel clock. This way we don't need to frob around with the core crtc mode set code. - Fixing up the pixelclock when constructing the sdvo dtd timing struct. This is why the first hunk of the patch is an integral part of the series. - Dropping the is_tv special case because input_dtd is equivalent to adjusted_mode after these changes. Follow-up patches clear this up further (by simply ripping out intel_sdvo->input_dtd because it's not needed). v2: Extend commit message with an in-depth bug analysis.

2012-04-22drm/i915: fixup load-detect on enabled, but not active pipeDaniel Vetter
Somehow we have a fast-path that tries to avoid going through the load-detect code when the encode already has a crtc associated. But this fails horribly when the crtc is off. The load detect pipe itself manages this case well (and also does not forget to restore the dpms state), so just rip out this special case.

2012-04-21VM: add "vm_mmap()" helper functionLinus Torvalds
This continues the theme started with vm_brk() and vm_munmap(): vm_mmap() does the same thing as do_mmap(), but additionally does the required VM locking. This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.

This fixes a resume regression introduced in commit 7dd4906586274f3945f2aeaaa5a33b451c3b4bba Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Mar 21 10:48:18 2012 +0000 drm/i915: Mark untiled BLT commands as fenced on gen2/3 which fixed fencing tracking for untiled blt commands. A side effect of that patch was that now also untiled objects have a non-zero obj->last_fenced_seqno to track when a fence can be set up after a pipelined tiling change. Unfortunately this was only cleared by the fence setup and teardown code, resulting in tons of untiled but inactive objects with non-zero last_fenced_seqno. Now after resume we completely reset the seqno tracking, both on the driver side (by setting dev_priv->next_seqno = 1) and on the hw side (by allocating a new hws page, which contains the seqnos). Hilarity and indefinite waits ensued from the stale seqnos in obj->last_fenced_seqno from before the suspend. The fix is to properly clear the fencing tracking state like we already do for the normal gpu rendering while moving objects off the active list. Reported-and-tested-by: "Rafael J.

2012-04-11drm/i915: implement ColorBlt w/aDaniel Vetter
According to an internal workaround master list, we need to set bit 5 of register 9400 to avoid issues with color blits. Testing shows that this seems to fix the blitter hangs when fbc is enabled on snb, thanks to Chris Wilson for figuring this out.

This reverts commit c3dfefa0a6d235bd465309e12f4c56ea16e71111. gmbus in 3.4 has simply too many known issues: - gmbus is too noisy, we need to rework the logging: https://bugs.freedesktop.org/show_bug.cgi?id=48248 - zero-length writes cause an OOPS, and they are userspace-triggerable: https://lkml.org/lkml/2012/3/30/176 - same for zero-length reads: https://bugs.freedesktop.org/show_bug.cgi?id=48269 We can try again for 3.5.

2012-04-11drm/radeon: only add the mm i2c bus if the hw_i2c module param is setAlex Deucher
It seems it can corrupt the monitor EDID in certain cases on certain boards when running sensors detect. It's rarely used anyway outside of AIW boards. http://lists.lm-sensors.org/pipermail/lm-sensors/2012-April/035847.html http://lists.freedesktop.org/archives/xorg/2011-January/052239.html Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
