drm/tegra: Changes for v4.15-rc1

This contains a bit of cleanup and some minor fixes for the host1x and
Tegra DRM drivers. There's also some more preparatory work for Tegra186
support which I'm not quite ready to send upstream because the GPIO
driver needed for HDMI support has been stuck for months, and we can't
do much without it. Hopefully that driver will land in v4.15, which
would mean we could go ahead with Tegra186 display support in v4.16.

6 years agodrm: Add CRTC_GET_SEQUENCE and CRTC_QUEUE_SEQUENCE ioctls [v3]

drm: Add CRTC_GET_SEQUENCE and CRTC_QUEUE_SEQUENCE ioctls [v3]

also offering higher resolution time (ns) and wider frame count (64)
as required by the Vulkan API.

v2:

 * Check for DRIVER_MODESET in new crtc-based vblank ioctls

Failing to check this will oops the driver.

 * Ensure vblank interupt is running in crtc_get_sequence ioctl

The sequence and timing values are not correct while the
interrupt is off, so make sure it's running before asking for
them.

 * Short-circuit get_sequence if the counter is enabled and accurate

Steal the idea from the code in wait_vblank to avoid the
expense of drm_vblank_get/put

 * Return active state of crtc in crtc_get_sequence ioctl

Might be useful for applications that aren't in charge of
modesetting?

 * Use drm_crtc_vblank_get/put in new crtc-based vblank sequence ioctls

Daniel Vetter prefers these over the old drm_vblank_put/get
APIs.

v2:

It wasn't being used anyways, and if we need it in the future,
we can always get it from crtc->dev.

The driver interfaces have been left using 32 bits of vblank count;

already included to handle devices returning fewer than 32-bits.

This will provide the necessary datatypes for the Vulkan API.

v2:

 * Re-write wait_vblank ioctl to ABSOLUTE sequence

    When an application uses the WAIT_VBLANK ioctl with RELATIVE
    or NEXTONMISS bits set, the target vblank interval is updated

    interrupted by a signal, when it is re-started, it will target

boards that had normal display output. By manually toggling these

pipelines are symmetrical (not considering the third display

Most notable addition this time is the support for the GPU performance
counters by Christian. This has been in the making for some time and it
has matured a lot. Since this is adding UAPI, the corresponding WIP

Christian sends out the final userspace patches for this once you have
pulled the kernel bits.

Philipp optimized the probe path, so etnaviv gets out of the way for
systems that want to boot real quick.

I've done mostly cleanups, disentangling etnaviv from the IOMMU API,
with some MMUv1 optimizations on the way.
