2014-08-10drm/nouveau/fifo: audit and version fifo channel classesBen Skeggs
The full object interfaces are about to be exposed to userspace, so we need to check for any security-related issues and version the structs to make it easier to handle any changes we may need in the future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-08-10drm/nouveau/nvif: import library functions for the ioctl/event interfacesBen Skeggs
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.

2014-08-10drm/nouveau/core: import ioctl/event interfacesBen Skeggs
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>

2014-08-10drm/nouveau/core: rework event interfaceBen Skeggs
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>

2014-08-10drm/nouveau: Bump version from 1.1.1 to 1.1.2Mario Kleiner
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.

2014-08-10drm/nouveau: Dis/Enable vblank irqs during suspend/resume.Mario Kleiner
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.

2014-08-10drm/nouveau/gk20a: reclocking supportAlexandre Courbot
Add support for reclocking on GK20A, using a statically-defined pstates table. The algorithms for calculating the coefficients and setting the clocks are directly taken from the ChromeOS kernel. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-08-10drm/nouveau/clk: support for non-BIOS pstatesAlexandre Courbot
Make nouveau_clock_create() take new two optional arguments: an array of pstates and its size. When these are specified, nouveau_clock_create() will use the provided pstates instead of probing them using the BIOS. This is useful for platforms which do not provide a BIOS, like Tegra.

2014-08-10drm/nve4/graph: do not crash if no power device presentAlexandre Courbot

2014-08-10drm/gk20a: add BAR instanceAlexandre Courbot

2014-08-10drm/nouveau/bar: add noncached ioremap propertyAlexandre Courbot
Some BARs (like GK20A's) do not support being ioremapped write-combined. Add a boolean property to the BAR structure and handle that case in the Nouveau BO implementation. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>
2014-08-10drm/nouveau: support for probing platform devicesAlexandre Courbot
Add a platform driver for Nouveau devices declared using the device tree or platform data. 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().
