2015-02-11xf86drmMode: Unconditionally clear ioctl structsDaniel Vetter
We really have to do this to avoid surprises when extending the ABI later on. Especially when growing the structures. Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>

2014-08-14drm: Implement drmCheckModesettingSupported() for DragonFlyFrançois Tigeot
For the sake of simplicity, KMS support can always be considered present on DragonFly. If some particular version doesn't support KMS yet, appropriate checks are already done in Dports's x11-drivers/ Makefiles and KMS-enabled driver packages don't get built.

2014-05-01Use signed location for drmModeSetPlaneDaniel Kurtz
DRM_IOCTL_MODE_SETPLANE crtc_x, crtc_y are s32. This is to allow a destination location that is partially off screen. Make this more obvious to users of libdrm by using signed crtc_x/_y parameters for drmModeSetPlane() as well.

2014-01-24drm: Implement drmCheckModesettingSupported() for FreeBSDRobert Millan

2014-01-20drm: Initialize or valgrind-clear modesetting ioctl arguments.Eric Anholt
Fixes valgrind complaints in the modesetting driver. I tried to follow each ioctl's pattern for whether it was initializing just the in values, or both in and out values. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

2012-10-14initialize width/height fields in drmModeCrtcRob Clark
If we have valid timings, we can at least set width/height to *something*, which is I think at least less confusing than always seeing width/height of zero. At least modeprint and modetest seem to expect width/height to mean something. Signed-off-by: Rob Clark <rob@ti.com>
2012-06-08Add support for bitmask propertiesRob Clark
A bitmask property is similar to an enum. The enum value is a bit position (0-63), and valid property values consist of a mask of zero or more of (1 << enum_val[n]). Signed-off-by: Rob Clark <rob@ti.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com>

2011-12-13libdrm: update drm headers from kernel, including new overlay ioctls & structsJesse Barnes

2011-09-18drm mode: fix drmIoctl wrapperMarcin Slusarz
Both drmIoctl and ioctl define second argument as unigned long. Debugging/tracing tools (like strace or valgrind) on 64-bit machines see different request value for ioctls with 32nd bit set, because casting signed int to unsigned long extends 32nd bit to upper word, so 0x80000000 becomes 0xFFFFFFFF80000000) Nobody noticed because higher 32 bits are chopped off on their way to kernel.

2010-07-01drm mode: Return -errno on drmIoctl() failureChris Wilson
The high layers expect to receive a status code on error (on the pessimistic assumption that the errno value will have been overwritten by the time the failure is propagated all the way up), so convert xf86drmMode.c to return -errno on an ioctl error and be consistent with the rest of the libdrm API.

2010-01-06modes: Retry GETCONNECTOR if a hotplug event occurs between the two ioctlsPeter Clifton
If the available modes changes between the two GETCONNECTOR ioctls, that caused the kernel to skip filling one array and led to a crash (as the size of the allocated and initialised block of memory differed from the reported size, and might be NULL if no modes were present at first). This bug manifest its self on my machine due to spurious false positive detections of a connected TV-out. Fixes: http://bugs.freedesktop.org/show_bug.cgi?id=25912 Crash whilst probing modes Based upon the similar fixes for the GETRESOURCES ioctls by Chris Wilson, in the following commits: commit e6c136ca7a4c54457b48be1aec2be024b3e4a28d commit 85fb3e55fdb7af9b5f59c1ec0f15d1950e601b05 commit d1308f4fe7f94aae51ca9f70947aea8e09597f37 Signed-off-by: Peter Clifton <pcjc2@cam.ac.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
