Fix indentation of vga_switcheroo sections in gpu.tmpl. Change section type of API documentation from "chapter" to "sect1" so that the individual functions no longer clutter up the ToC. Group together under a new "API" chapter. Fix wording "heretoforth" -> "henceforth". Signed-off-by:

pan_display_atomic() calls drm_atomic_clean_old_fb() to sanitize the legacy FB fields (plane->fb and plane->old_fb). However it was building the plane mask to pass to this function incorrectly (the bitwise OR was using plane indices rather than plane masks). The end result was that sometimes the legacy pointers would become out of sync with the atomic pointers. If another operation tried to re-set the same FB onto the plane, we might end up with the pointers back in sync, but improper reference counts, which would eventually lead to system crashes when we accessed a pointer to a prematurely-destroyed FB. The cause here was a very subtle bug introduced in commit: commit 07d3bad6 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Wed Nov 11 11:29:11 2015 +0100 drm/core: Fix old_fb handling in pan_display_atomic. I found the crashes were most easily reproduced (on i915 at least) by starting X and then VT switching to a VT that wasn't running a console instance...the sequence of vt/fbcon entries that happen in that case trigger a reference count mismatch and crash the system.

The following code pattern exists in some DRM drivers: ddev = drm_dev_alloc(&driver, parent_dev); drm_dev_set_unique(ddev, dev_name(parent_dev)); (Sometimes dev_name(ddev->dev) is used, which is the same.) As suggested in http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html, the unique name of a new DRM device can be set as dev_name(parent_dev) when parent_dev is not NULL (vgem is a special case).

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(). Signed-off-by: -

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:

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.
