2018-03-20meson,configure: include config.h automaticallyEric Engestrom1-4/+0
This will prevent any more missing `#include "config.h"` bug, at the cost of having to recompile some files that didn't need to be when changing build options. Signed-off-by: Eric Engestrom <eric.engestrom@imgtec.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com>
2015-12-22nouveau: add support for newer kernel interfacesBen Skeggs1-1/+2

2015-12-22nouveau: make use of nouveau_drm::fd instead of nouveau_device::fdBen Skeggs1-17/+15
The latter is deprecated, and will not be valid for newer clients. v2. - split out nouveau_object_find removal Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Tested-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>
2015-12-22nouveau: add interfaces to query information about supported classesBen Skeggs1-1/+50
This will expose functionality supported by newer kernel interfaces. Current userspace uses the chipset to determine which classes are likely exposed, which generally works pretty well, but isn't as flexible as it could be. Unfortunately, the G98:GF100 video code in Mesa is still relying on the kernel exposing incorrect vdec classes on some chipsets. The ABI16 kernel interfaces have a workaround for this in place, but that will no longer be available once libdrm supports NVIF. To prevent a regression when NVIF support is added, if there's no kernel support for NVIF, libdrm will magic up a class list containing correct vdec classes anyway instead of failing with -ENODEV. v2. - add description of abi16/vdec workaround - add description of sclass/mclass - leave client-provided pointer unmodified on abi16_sclass() failure Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Tested-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>

2015-05-21nouveau: add coherent BO attributeAlexandre Courbot1-0/+3
Add a flag allowing Nouveau to specify that an object should be coherent at allocation time. This is required for some class of objects like fences which are randomly-accessed by both the CPU and GPU. This flag instructs the kernel driver to make sure the object remains coherent even on architectures for which coherency is not guaranteed by the bus.

2015-04-28nouveau: annotate the private symbolsEmil Velikov1-7/+7
They are less and easier to track than the public ones. The macro drm_public will be going away by the end of the series. Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>

2012-06-09nouveau: silence some remaining valgrind warningsMarcin Slusarz1-4/+1
Valgrind can't understand some of the fields passed to ioctls are overwritten by kernel, so we need to initialize them. Almost all of our ioctl wrappers already do it and the cost of remaining 3 is very small. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com>

2012-04-14nouveau: pull in major libdrm rewriteBen Skeggs1-0/+197
Redesigned primarily to allow us to better take advantage of BO's having fixed GPU virtual addresses on GeForce 8 and up, and to reduce the overhead of handling relocations on earlier chipsets.
