drm_dev_set_unique() uses a format string to define the unique name of a device. This feature is not used as currently all the calls to this function either use "%s" as a format string or directly use dev_name(). Even though this second kind of call does not introduce security problems, because there cannot be "%" characters in dev_name() results, gcc issues a warning when building with -Wformat-security flag ("warning: format string is not a string literal (potentially insecure)"). This warning is useful to find real bugs like the one fixed by commit 3958b792 ("configfs: fix kernel infoleak through user-controlled format string"). False positives which do not bring an extra value make the work of finding real bugs harder. Therefore remove the format-string feature from drm_dev_set_unique().

Thierry Reding authored
Previously a negative pipe caused a special case to be triggered for drivers that didn't have proper VBLANK support. The trigger for this special case is now independent of the pipe, so the correct CRTC index can now be stored in events. v2: convert to use drm_crtc_send_vblank_event() Cc: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by:

If the DSI output isn't connected, then mdfld_dsi_encoder_get_pipe() will return -1.

VC4 wraps the CMA objects in its own structures, so it needs to do its own teardown (waiting for GPU to finish, updating bo_stats tracking). The other CMA drivers are using drm_gem_cma_free_object as their gem_free_object, so this should be a no-op for them. Signed-off-by:

DRM Docbook is now Markdown ready. This means its doc is able to use markdown text on it. * Documentation/DocBook/drm.tmpl: Contains a table duplicated from drivers/gpu/drm/i915/i915_reg.h. This is not needed anymore * drivers/gpu/drm/drm_modeset_lock.c: had a code example that used to look pretty bad on html. Fixed by using proper code markup. * drivers/gpu/drm/drm_prime.c: Remove spaces between lines to make a proper markup list. * drivers/gpu/drm/i915/i915_reg.h: Altought pandoc supports tables, it doesn't support table cell spanning. But we can use fixed-width for those special cases. * include/drm/drm_vma_manager.h: Another code example that should be proper indented with four spaces. v2 (Daniel): Adjust name to gpu.xml due to rename. v3 (Daniel): Split out the actual enabling in the Makefile - this way we can merge the conversion, while just keeping the enabling in a drm-private tree.

This patch series adds of_graph based dt binding for DP panel. And also it keeps backward compatibility. This includes dt binding patch so I got Acked-by from Krzysztof Kozlowski who is a Exynos SoC maintainer and from Rob Herring who is a device tree maintainer. - Cleanup for Exynos DRM IPP enhancement. .
