drm/i915/vlv: Add drpc debugfs support for valleyview

2014-01-10T17:00:14+00:00

Many of the fields from Gen6 have gone away for vlv. Strip all those fields that are not relevent and try to update fields that we care about. This patch give information about current RP & RC status and individual Wells. v2: Move Render & Media Well status to separate lines (Ville) Signed-off-by: Deepak S Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter

My OCD just couldn't let this slide. Spotted while reviewing Ville's patch to only flip planes when we have FBC. Cc: Ville Syrjälä Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter

drm/i915/bdw: don't try to check IPS state on BDW v2

2014-01-08T14:48:57+00:00

According to Art, we don't have a way to read back the state reliably at runtime, through the control reg or the mailbox, at least not without risking disabling it again. So drop the readout and checking on BDW. v2: drop TODO comment (Paulo) move POSTING_READ of control reg under HSW branch in disable (Paulo) always report IPS as enabled on BDW (Paulo) References: https://bugs.freedesktop.org/show_bug.cgi?id=71906 Signed-off-by: Jesse Barnes Reviewed-by: Paulo Zanoni Signed-off-by: Daniel Vetter

drm/i915: Fix refcount leak and possible NULL pointerdereference.

2014-01-06T09:56:36+00:00

Since get_pid_task() grabs a reference on the task_struct, we have to drop the refcount after reading that task's comm name. Use pid_task() with RCU instead. Also, avoid directly reading like pid_task()->comm because pid_task() will return NULL if the task have already exit()ed. This patch fixes both problems.

drm/i915: only build i915_debugfs.c when CONFIG_DEBUG_FS is enabled

2013-12-16T15:53:32+00:00

The whole file is wrapped around in #if defined(CONFIG_DEBUG_FS) anyway, so skip the file at the build level already. Signed-off-by: Jani Nikula Signed-off-by: Daniel Vetter

drm/i915: fix return value check of debugfs_create_file()

2013-12-16T10:04:43+00:00

In case of error, the function debugfs_create_file() returns NULL pointer not ERR_PTR() if debugfs is enabled. The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun Signed-off-by: Daniel Vetter
