drm/i915: Add GEM debugging Kconfig option

2016-04-14T09:45:40+00:00

Currently there is a #define to enable extra BUG_ON for debugging requests and associated activities. I want to expand its use to cover all of GEM internals (so that we can saturate the code with asserts). We can add a Kconfig option to make it easier to enable - with the usual caveats of not enabling unless explicitly requested.

drm/i915: Force clean compilation with -Werror

2016-04-14T09:45:40+00:00

Our driver compiles clean (nowadays thanks to 0day) but for me, at least, it would be beneficial if the compiler threw an error rather than a warning when it found a piece of suspect code. (I use this to compile-check patch series and want to break on the first compiler error in order to fix the patch.) v2: Kick off a new "Debugging" submenu for i915.ko At this point, we applied it to the kernel and promptly kicked it out again as it broke buildbots (due to a compiler warning on 32bits): commit 908d759b210effb33d927a8cb6603a16448474e4 Author: Daniel Vetter Date: Tue May 26 07:46:21 2015 +0200 Revert "drm/i915: Force clean compilation with -Werror" v3: Avoid enabling -Werror for allyesconfig/allmodconfig builds, using COMPILE_TEST as a suitable proxy suggested by Andrew Morton. (Damien) Only make the option available for EXPERT to reinforce that the option should not be casually enabled.

This reverts commit 118182e9d7d5afa0c7c10f568afb46ab78b462e9. It's causing too much trouble when compile-testing for non-i915 folks. Cc: Chris Wilson Cc: Jani Nikula Cc: Andrew Morton Signed-off-by: Daniel Vetter
