From: Damien Lespiau Date: Fri, 7 Feb 2014 19:12:48 +0000 (+0000) Subject: drm/i915: Make the intel_device_info structure kept in dev_priv writable X-Git-Tag: firefly_0821_release~176^2~4105^2~59^2~62 X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=5c969aa7e152e9eafd8cb3c2788649d168c2ebac;p=firefly-linux-kernel-4.4.55.git drm/i915: Make the intel_device_info structure kept in dev_priv writable Turns out it'd be nice to change some device information at run-time or simply have some code to fill in the info struct instead of having to declare the values in 30+ structures. What prompted this change is handling fused out display/pipe and tweaking num_pipes at run-time, but I'm quite sure we'll find other flags/limits to stick into dev_priv->info. Most of the changes were done with a sed: sed -i -e 's/dev_priv->info->/dev_priv->info./g' drivers/gpu/drm/i915/*[ch] with a few tweaks to make it all work: - Change the field definition in struct drm_i915_private - adjust i915_dump_device_info() - adjust i915_driver_load() - adjust the INTEL_INFO() macro v2: cast the info pointer returned by INTEL_INFO() to be const to catch uses that would modify the structure post-initialization. (Ville Syrjälä) v3: Redo the patch onto latest drm-nightly, Keep the info field const to catch post initialization writes instead of the v2 solution, Use a direct structure copy for the initial info initialization to use the compiler type safety (Ville Syrjälä) Reviewed-by: Mika Kuoppala (for v2) Reviewed-by: Ville Syrjälä (for v2) Signed-off-by: Damien Lespiau Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_dma.c b/drivers/gpu/drm/i915/i915_dma.c index 258b1be20db3..0a9d0adc5a63 100644 --- a/drivers/gpu/drm/i915/i915_dma.c +++ b/drivers/gpu/drm/i915/i915_dma.c @@ -1442,7 +1442,7 @@ static void i915_kick_out_firmware_fb(struct drm_i915_private *dev_priv) static void i915_dump_device_info(struct drm_i915_private *dev_priv) { -
