2012-05-22snowball: android: mali: Disable profiling of Mali L2 cacheJon Medhurst (Tixy)
When connecting the ARM Streamline Performance Analyzer to Snowball Android this will cause a board lock-up if the screen is static (Bug #961962). The cause of this appears to be a know issue with reading the L2 cache performance counters whilst the hardware block is powered down. As the current code is written to access these counters even when they have not been explicitly selected then this issue prevents Streamline being used reliably for any purpose. To workaround this bug, this patch disables support for the L2 cache counters in Mali. This has no effect on the operation of the cache. Signed-off-by: Jon Medhurst <tixy@linaro.org>
2012-05-22snowball: android: mali: Add Streamline Support for Mali DDKJon Medhurst (Tixy)
ARM's Streamline Performance Analyzer now supports Mali graphics. This requires support from the Mali kernel module which this patch adds. These changes were delivered by ARM Ltd in a patch file called: r2p3-01rel0_gpl_driver_streamline_support.patch that came with a README.txt which included the following... BUILDING THE DRIVER The driver can be built as normal. Profiling instrumentation is enabled by default by the patch. To disable it, use USING_PROFILING=0 in your build command. To revert to the old-style profiling code, use USING_INTERNAL_PROFILING=1 this option will disable the Streamline profiling support. KNOWN ISSUES * Attempting to read L2 cache counters when the hardware block is powered down could potentially lead to a hang due to a lack of locking. This will be addressed in a future driver update. Signed-off-by: Jon Medhurst <tixy@linaro.org>

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.

2012-04-20VM: 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.
