| | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/mc: take nvkm_device as argument to public functionsBen Skeggs2016-07-141-1/+1
| | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/core: remove pmc_enable argument from subdev ctorBen Skeggs2016-05-202-10/+7
| | | | | | These are now specified directly in the MC subdev. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/mc: add helper function to handle device resetBen Skeggs2016-05-201-6/+2
| | | | | | | This will be later extended to handle PTOP-specified reset masks as well as the hardcoded ones. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau/core: use vzalloc for allocating ramhtIlia Mirkin2016-03-141-3/+3
| | | | | | | | | | Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a fairly sizeable chunk of memory to be allocated, which may not be available with kzalloc. Since this is done fairly rarely (once per channel), use vzalloc instead. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/subdev/iccsense: add new subdev for power sensorsMartin Peres2016-03-141-42/+43

* drm/nouveau/core: add support for secure bootAlexandre Courbot2016-03-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | On GM200 and later GPUs, firmware for some essential falcons (notably GR ones) must be authenticated by a NVIDIA-produced signature and loaded by a high-secure falcon in order to be able to access privileged registers, in a process known as Secure Boot. Secure Boot requires building a binary blob containing the firmwares and signatures of the falcons to be loaded. This blob is then given to a high-secure falcon running a signed loader firmware that copies the blob into a write-protected region, checks that the signatures are valid, and finally loads the verified firmware into the managed falcons and switches them to privileged mode. This patch adds infrastructure code to support this process on chips that require it. v2: - The IRQ mask of the PMU falcon was left - replace it with the proper irq_mask variable. - The falcon reset procedure expecting a falcon in an initialized state, which was accidentally provided by the PMU subdev. Make sure that secboot can manage the falcon on its own. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/core: add gpuobj memcpy helper functionsAlexandre Courbot2016-03-141-0/+20
| | | | | | | | Add memcpy functions to copy a buffer to a gpuobj and vice-versa. This will be used by the secure boot code. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/core: add firmware handling functionsAlexandre Courbot2016-03-142-0/+62
| | | | | | | | | | | Add two functions nvkm_firmware_get() and nvkm_firmware_put() to load a firmware file and free its resources, respectively. Since firmware files are becoming a necessity for new GPUs, and their location has been standardized to nvidia/chip/, this will prevent duplicate and error-prone name-generation code.
