2014-03-26drm/nouveau: use nv_debug for NV_DEBUG, make DRM a separate subflagIlia Mirkin1-4/+1
It's really confusing for NV_DEBUG's printing to be controlled via drm.debug while everything else is controlled via nouveau.debug. These messages can be turned on with nouveau.debug=DRM=debug. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-11-08drm/nouveau/core: make all info-level messages silent for runtime pmBen Skeggs1-1/+0
Removes the need for special handling of messages in init paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-11-08drm/nouveau/core: convert event handler apis to split create/enable semanticsBen Skeggs1-1/+0
This is a necessary step towards being able to work with the insane locking requirements of the DRM core's vblank routines, and a nice cleanup as a side-effect. This is similar in spirit to the interfaces that Peter Hurley arrived at with his nouveau_event rcu conversion series. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-08-29nouveau: add runtime PM support (v0.9)Dave Airlie1-0/+9
This hooks nouveau up to the runtime PM system to enable dynamic power management for secondary GPUs in switchable and optimus laptops. a) rewrite suspend/resume printks to hide them during dynamic s/r to avoid cluttering logs b) add runtime pm suspend to irq handler, crtc display, ioctl handler, connector status, c) handle hdmi audio dynamic power on/off using magic register. v0.5: make sure we hit D3 properly fix fbdev_set_suspend locking interaction, we only will poweroff if we have no active crtcs/fbcon anyways. add reference for active crtcs. sprinkle mark last busy for autosuspend timeout v0.6: allow more flexible debugging - to avoid log spam add option to enable/disable dynpm got to D3Cold v0.7: add hdmi audio support. v0.8: call autosuspend from idle, so pci config space access doesn't go straight back to sleep, this makes starting X faster. only signal usage if we actually handle the irq, otherwise usb keeps us awake. fix nv50 display active powerdown v0.9: use masking function to enable hdmi audio set busy when we fail to suspend Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-02-20drm/nouveau/disp: port vblank handling to event interfaceBen Skeggs1-0/+2
This removes the nastiness with the interactions between display and software engines when handling vblank semaphore release interrupts. Now, all the semantics are handled in one place (sw) \o/. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau: convert to dev_pm_opsDave Airlie1-2/+2
This is a precursor to dynamic power management support for nouveau, we need to use pm ops for that, so first convert the driver to using pm ops interfaces. Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds1-0/+144
Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...

2012-10-03drm/nve0: use async copy engine for ttm buffer moves if availableBen Skeggs1-0/+1

2012-10-03drm/nouveau: port all engines to new engine module formatBen Skeggs1-0/+68
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>

2012-10-03drm/nouveau: implement module init functions in nouveau_drm.cBen Skeggs1-0/+47
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>
