2012-10-03Merge branch 'drm-nouveau-next' of ↵Dave Airlie
git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next This is a major rework of the nouveau driver core, to reflect more closely how the hw is used and to make it easier to implement newer features now that the GPUs are more clearly understood than when nouveau started. It also contains a few other bits: thermal patches nv41/44 pcie gart fixes i2c unregistering fixes. * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (191 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/nv41/vm: fix and enable use of "real" pciegartBen Skeggs
Hopefully fixed the tlb flush timeout issue. Was able to observe this condition occur occasionally, and it appears the binary driver doesn't wait on the old condition either.. Should give 39-bit DMA addressing on the relevant chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nv44/vm: fix and enable use of "real" pciegartBen Skeggs
Something seems to be missing in regards to flushing specific ranges of the TLB. For the moment, flushing the entire thing seems to make it work alright. Should give 39-bit DMA addressing on the relevant chipsets. v2: allocate contig 16KiB for dummy pages, reported by mwk on irc Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcieBen Skeggs
We don't need to pull the page address out of the page tables on nv4x chips that have a real GART. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau/therm: add support for fan-control modesMartin Peres
For now, only 2 control modes are available: - NONE: The fan is never touched (default) - MANUAL: The fan is set to the user-defined fan speed (pwm1) This patch introduces a distinction between ptherm internal fan management and external fan management. The latter is bound to respect the fan mode while the first can still select the speed it wants unless the NONE mode is selected. This is important for automatic fan management.

2012-10-03drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rulesMartin Peres

2012-10-03drm/nouveau/therm: calculate the pwm divisor on nv50+Martin Peres
v2: Martin Peres <martin.peres@labri.fr> - fixed unintentional use of floating point Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, fasterMartin Peres
The previous driver waited for 250ms to accumulate data. This version times a complete fan rotation and extrapolates to RPM. The fan rotational speed should now be read in less than 250ms (worst case) and usually in less 50ms.

2012-10-03drm/nouveau/therm: move thermal-related functions to the therm subdevMartin Peres
It looks scary because of the size, but I tried to keep the differences minimal. Further patches will fix the actual "driver" code and add new features. v2: change filenames, split to submodules v3: add a missing include v4: Ben Skeggs <bskeggs@redhat.com> - fixed set_defaults() to allow min_duty < 30 (thermal table will override this if it's actually necessary) - fixed set_defaults() to not provide pwm_freq so nv4x (which only has pwm_div) can actually work. the boards using pwm_freq will have a thermal table entry to provide us the value. - removed unused files Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/bios: parse the pwm divisor from the perf tableMartin Peres

2012-10-03drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devicesMartin Peres

2012-10-03drm/nouveau/therm: rework thermal table parsingMartin Peres
As an accident, it should also fix temperature reading on nv4x. v2: introduce nvbios_therm_entry as advised by darktama Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau: fix pm initialization orderDmitry Eremin-Solenikov

Not really sure how to confirm this 100%, but, the numbers match on all the traces I have for NVCx (2 LTS), NVD9 (1LTS) and NVEx (4LTS). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nve0/gr: enable use of our fuc by defaultBen Skeggs

2012-10-03drm/nve0/gr: remove 0x404160 bashing from hub fucBen Skeggs
Triggers PIBUS interrupts due to register not existing anymore, and as a result HUB_SET_CHAN times out. After this commit, our fuc loads and can accelerate at least fbcon, X, glxgears and OA on NVE4. NVE7 not tested as of yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nve0/gr: initial fuc implementation, based on fermi's codeBen Skeggs
Currently identical except the available chipset register lists. This will *not* currently work and is disabled by default because of this. May get merged again later, remains to be seen what further changes will be required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau/core: have fifo store a unique context identifier at attach timeBen Skeggs
This value will match something that's easily available from the engine IRQ handlers, and used to lookup the relevant context. Since the changes in how this is done on each generation match when the major PFIFO changes happened, fifo is responsible for calculating the correct value to avoid duplicating the same code among many engine modules.
