* drm/nouveau/mc: handle irq-related setup ourselvesBen Skeggs2013-04-261-76/+0
| | | | | | | | We need to be able to process interrupts before the DRM code is able to actually enable them, set it up ourselves. Also, it's less convoluted to *not* use the DRM wrappers it appears... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: port all engines to new engine module formatBen Skeggs2012-10-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | These currently just call the existing ones in nouveau_drv.c, but will be extended in upcoming commits. This needed to be separated from the current code as there will be some header clashes until things are ported. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs2012-10-031-1/+1
| | | | | | | | | | | | | | Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: add support for MSIBen Skeggs2010-12-031-0/+35
| | | | | | | | | | | | | | | | Only supported on NV50+ so far, and disabled by default currently. The module parameter "msi=1" will enable it. There's a kernel bug which will cause this to fail if the module (or the NVIDIA binary driver) has ever been loaded before loading nouveau with MSI enabled. As such, this is only safe to enable if you have nouveau load on boot, and don't wish to ever reload it. The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable" until the enable count reads 0. Then you should be able to load nouveau with MSI enabled.

* drm/nouveau: handle fifo pusher errors betterBen Skeggs2010-09-241-8/+37
| | | | | | | | | | | | The most important part of this change is that we now instruct PFIFO to drop all pending fetches, rather than attempting to skip a single dword and hope that things would magically sort themselves out - they usually don't, and we end up with PFIFO being completely hung.

| * drm/fb: fix fbdev object model + cleanup properly.Dave Airlie2010-04-071-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work. This patch a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs. b) migrated all the fb helper functions out of the crtc helper file into the fb helper file. c) pushed the fb probing/hotplug control into the driver d) makes the surface sizes into a structure for ease of passing This changes the intel/radeon/nouveau drivers to use the new helper.

* drm/nv50: Improve PGRAPH interrupt handling.Marcin Kościelnicki2010-03-101-48/+561
| | | | | | | | | | | | | This makes nouveau recognise and report more kinds of PGRAPH errors, as well as prevent GPU lockups resulting from some of them. Lots of guesswork was involved and some part of this is probably incorrect. Some potential-lockuop situations are handled by just resetting a whole PGRAPH subunit, which doesn't sound like a "proper" solution, but seems to work just fine... for now.

* drm/nouveau: Fixup semaphores on pre-nv50 cards.Francisco Jerez2010-02-091-0/+14
| | | | | | | | | | Apparently, they generate a PFIFO interrupt each time one of the semaphore methods is executed if its ctxdma wasn't manually marked as valid. This patch makes it flip the valid bit in response to the DMA_SEMAPHORE method (which triggers the IRQ even for a valid ctxdma).

* drm/nouveau: Acknowledge DMA_VTX_PROTECTION PGRAPH interruptsLuca Barbieri2010-01-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently Nouveau is unable to dismiss DMA_VTX_PROTECTION errors, which results in an infinite loop in the interrupt handler. These errors are caused both by bugs in the Gallium driver and by user-specified index buffers with out of bounds indices. By mmio-tracing the nVidia drivers, I found out how this is done. On DMA_VTX_PROTECTION, The nVidia driver reads the register 0x402000, always getting the value 4, and then writes 4 back to 0x402000. This patch adds that logic by reading 0x402000 and writing the same value back. It's unclear what should happen if the value read is not 4, and the current approach might not be the correct one. To test this, modify mesa/progs/trivial/vbo-drawrange.c, defining ELTOBJ to 1 and replacing indices with huge out of bounds integers. Without this patch, the GPU and/or kernel should lock up. With this patch, it should misrender as expected but not lock up. The errors are still logged since they are useful for development. This has been tested on NV49 and may not work on other cards. To find out how things work on other cards, run the aforementioned test using the blob with mmiotrace and grep for a read of the PGRAPH source register.

* drm/nv50: prevent a possible ctxprog hangBen Skeggs2010-01-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | The below is mainly an educated guess at what's going on, docs would sure be handy... NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs2009-12-111-0/+702
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.
