| * | | | drm/i915: Fix HDMI mode select for Cougarpoint PCHZhenyu Wang2010-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For real HDMI sink, CPT HDMI port has to set 'HDMI' mode flag in order to make HDMI audio work correctly. This is required patch for drm/i915 to enable HDMI audio on CPT PCH, ALSA patch is at http://mailman.alsa-project.org/pipermail/alsa-devel/2010-May/027601.html Tested-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This saves a whooping 7 dwords. Zero functional changes. Because some of the refcounts are rather tightly calculated, I've put BUG_ONs in the code to check for overflows.

Therefore we can expect to hit intel_finish_page_flip() under normal circumstances without a pending flip and even without installing the pending_flip_obj. This is exacerbated by aperture thrashing whilst binding the framebuffer References: Bug 28079 - "glresize" causes kernel panic in intel_finish_page_flip. https://bugs.freedesktop.org/show_bug.cgi?id=28079 Reported-by: Nick Bowler <nbowler@draconx.ca> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: stable@kernel.org Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

By the point at which we detect broken a BIOS and need to disable GEM, we have already registered ourselves as a KMS driver with several subsystems. Rather than introducing a fragile unwind and attempt to continue with UMS, spit out an error and unload the driver.

Quote Tim Bird: | I've been bitten by this numerous times. I most often | use ftrace on ARM, but when I go back to x86, I almost | always go through a sequence of searching for the | function graph tracer in the menus, then realizing it's | completely missing until I disable CC_OPTIMIZE_FOR_SIZE. | | Is there any way to have the menu item appear, but be | unsettable unless the SIZE option is disabled? I'm | not a Kconfig guru... I myself found this useful too. For example, I need to test ftrace/tracing and want to be sure all the tracing features are enabled, so I enter the "Tracers" menu, and press <Z> to see if there is any config hidden. I also noticed gconfig and xconfig have a button "Show all options", but that's a bit too much, and I think normally what we are not interested in those configs which have no prompt thus can't be changed by users. Exmaple: --- Tracers -*- Kernel Function Tracer - - Kernel Function Graph Tracer [*] Interrupts-off Latency Tracer - - Preemption-off Latency Tracer [*] Sysprof Tracer Here you can see 2 tracers are not selectable, and then can find out how to make them selectable.

See page 199 of PBP. (Severity: 5) The rationale according to PBP is that an explicit return of undef (contrary to most people's expectations) doesn't always evaluate as false. It has to with the fact that perl return value depends on context the function is called. If function is used in list context, the appropriate return value for false is an empty list; whereas in scalar context the return value for false is undefined. By just using a "return" both cases are handled. In the context of a trivial script this doesn't matter. But one script may be cut-paste into later code (most people like me only know 50% of perl), that is why perlcritic always complains Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
