* drm/nouveau/fifo: allow direct access to channel control registers where ↵Ben Skeggs2014-08-1011-9/+38
| | | | | | | | | | | | | | | possible The indirect method has been left in-place here as a fallback path, as it may not be possible to map the non-PAGE_SIZE aligned control areas across some chipset+interface combinations. This isn't a problem for the primary use-case where the core and drm are linked together in kernel-land, but across a VM or (in the case where it applies now) between the core in the kernel and a userspace test tool.

| | | | | | | | | | | | This is a wrapper around the interfaces defined in an earlier commit, and is also used by various userspace (either by a libdrm backend, or libpciaccess) tools/tests. In the future this will be extended to handle channels, replacing some long-unloved code we currently use, and allow fifo/display/mpeg (hi Ilia ;)) engines to all be exposed in the same way.

* drm/nouveau/core: import ioctl/event interfacesBen Skeggs2014-08-1013-4/+831
| | | | | | | | | | | | | | | | | | This forms the basis for the new APIs that will be exposed to userspace, giving it access to: - Object method calls, the immediately useful of which is performance counters and the abiity to manipulate the ZBC tables. - Information on the child classes an object supports, in order to avoid having to try all supported classes until successful. - Notifications, which will be used in the future to inform the client if its channel was killed due to a lockup, etc. This commit imports the interfaces, but are not currently used. The DRM portion of the driver will be ported to speak to the core using these interfaces as much as possible. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau/core: rework event interfaceBen Skeggs2014-08-1052-517/+875
| | | | | | | | | | | | | | | This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Bump version from 1.1.1 to 1.1.2Mario Kleiner2014-08-101-1/+3
| | | | | | | | | | | | | | | | | | Linux 3.16 fixed multiple bugs in kms pageflip completion events and timestamping, which were originally introduced in Linux 3.13. These fixes have been backported to all stable kernels since 3.13. However, the userspace nouveau-ddx needs to be aware if it is running on a kernel on which these bugs are fixed, or not. Bump the patchlevel of the drm driver version to signal this, so backporting this patch to stable 3.13+ kernels will give the ddx the required info.

* drm/nouveau: Dis/Enable vblank irqs during suspend/resume.Mario Kleiner2014-08-101-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vblank irqs don't get disabled during suspend or driver unload, which causes irq delivery after "suspend" or driver unload, at least until the gpu is powered off. This could race with drm_vblank_cleanup() in the case of nouveau and cause a use-after-free bug if the driver is unloaded. More annoyingly during everyday use, at least on nv50 display engine (likely also others), vblank irqs are off after a resume from suspend, but the drm doesn't know this, so all vblank related functionality is dead after a resume. E.g., all windowed OpenGL clients will hang at swapbuffers time, as well as many fullscreen clients in many cases. This makes suspend/resume useless if one wants to use any OpenGL apps after the resume. In Linux 3.16, drm_vblank_on() was added, complementing the older drm_vblank_off() to solve these problems elegantly, so use those calls in nouveaus suspend/resume code. For kernels 3.8 - 3.15, we need to cherry-pick the drm_vblank_on() patch to support this patch.

This driver currently supports GK20A on Tegra platforms and is only compiled for these platforms if Nouveau is enabled. Nouveau will probe the chip type itself using the BOOT0 register, so all this driver really needs to do is to make sure the module is powered and its clocks active before calling nouveau_drm_platform_probe().
