2017-02-17drm/nouveau/secboot: rename init() hook to oneinit()Alexandre Courbot
The init() hook is called by the subdev's oneinit(). Rename it accordingly to avoid confusion about the lifetime of objects allocated in it. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/secboot: remove nvkm_secboot_start()Alexandre Courbot
Since GR has moved to using the falcon library to start the falcons, this function is not needed anymore. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/secboot: use falcon libraryAlexandre Courbot
Use the falcon library functions in secure boot. This removes a lot of code and makes the secure boot flow easier to understand as no register is directly accessed. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/secboot: fix functions definitionsAlexandre Courbot
These functions should use the nvkm_secboot_falcon enum. Fix this. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/gm20b: add dummy PMU deviceAlexandre Courbot
Add a dummy PMU device so the PMU falcon is instanciated and can be used by secure boot. We could reuse gk20a's implementation here, but it would fight with secboot over PMU falcon's ownership and secboot will reset the PMU, preventing it from operating afterwards. Proper handout between secboot and pmu is coming along with the actual gm20b PMU implementation, so use this as a temporary solution.

2017-02-17drm/nouveau/pmu/gk20a: use falcon library functionsAlexandre Courbot

2017-02-17drm/nouveau/pmu/gk20a: simplify code a bitAlexandre Courbot
Some functions always succeed - change their return type to void and remove the error-handling code in their caller. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/pmu/gk20a: use nvkm_pmu_ctor()Alexandre Courbot
Use the PMU constructor so that all base members (in particular the falcon instance) are initialized properly. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/pmu: instanciate the falcon in PMU deviceAlexandre Courbot
Have an instance of nvkm_falcon in the PMU structure, ready to be used by other subdevs (i.e. secboot). Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/pmu: add nvkm_pmu_ctor() functionAlexandre Courbot
Add a PMU constructor so implementations that extend the nvkm_pmu structure can have all base members properly initialized. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-02-17drm/nouveau/mc: add nvkm_mc_enabled() functionAlexandre Courbot
Add a function that allows us to query whether a given subdev is currently enabled or not. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-12-06drm/nouveau/mxm: handle DCB 4.1 modificationBen Skeggs

2016-12-06drm/nouveau/bios/mxm: handle digital connector table 1.1Ben Skeggs
I suspect the version bump is just to signify that the table now specifies pad macro/links instead of SOR/sublinks. For our usage of the table, just recognising the new version is enough. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-28drm/nouveau/fb/ram/gp100-: fix memory detection where FBP_NUM != FBPA_NUMBen Skeggs

2016-11-17drm/nouveau/devinit/gm200: drop pmu reset sequenceBen Skeggs
This sequence is incorrect for GP102/GP104 boards. This is now being handled correctly by the PMU subdev during preinit(); Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-17drm/nouveau/devinit/gm200: replace while loops with PTIMER-based timeout loopsBen Skeggs
It appears to be safe to access PTIMER on an unposted board with newer chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-17drm/nouveau/pmu/gp102: initial implementationBen Skeggs
GP102/GP104 require a harder reset of PMU prior to DEVINIT, or the IFR image will hang. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-11-07drm/nouveau/fb: add gm20b deviceAlexandre Courbot
gm20b's FB has the same capabilities as gm200, minus the ability to allocate RAM. Create a device that reflects this instead of re-using the gk20a device which may be incorrect.

2016-11-07drm/nouveau/fb/gk20a: use regular gf100's functionsAlexandre Courbot
gk20a's FB is not special compared to other Kepler chips, besides the fact it does not have VRAM. Use the regular gf100 hooks instead of the incomplete versions we rewrote.

2016-11-07drm/nouveau/fb/gk20a: fix constructor callAlexandre Courbot
The gf100 constructor should be called, otherwise we will allocate a smaller object than expected. This was without effect so far because gk20a did not allocate a page, but with gf100's page allocation moved to the oneinit() hook this problem has become apparent.

2016-11-07drm/nouveau/i2c/aux/g94-: retry transactions after hw reports an errorBen Skeggs
This fixes (works around?) link training failures seen on (at least) the Lenovo P50's internal panel. It's also an important fix on the same system for MST support on the dock. Sometimes, right after receiving an IRQ from the sink, there's an error bit (SINKSTAT_ERR) set in the DPAUX registers before we've even attempted a transaction. v2.

2016-10-12drm/nouveau/fb/nv50: defer DMA mapping of scratch page to oneinit() hookArd Biesheuvel
The 100c08 scratch page is mapped using dma_map_page() before the TTM layer has had a chance to set the DMA mask. This means we are still running with the default of 32 when this code executes, and this causes problems for platforms with no memory below 4 GB (such as AMD Seattle) So move the dma_map_page() to the .oneinit hook, which executes after the DMA mask has been set.

2016-10-12drm/nouveau/volt: Make use of cvb coefficientsKarol Herbst
I'm quite sure that those coefficients are real close, because while testing the biggest error compared to nvidia was around -1.5% (biggest error with right coefficients is 12.5mV / 600mV = 2%). These coefficients were REed by modifing the voltage map entries and by calculating the set voltage back until I was able to forecast which voltage nvidia sets for a given voltage map entry. With these formulars I am able to precisely predict at which exact temperature Nvidia down- or upvolts due to a changed therm reading. That's why I am quite sure these are right, or at least really really close. v4: Use better coefficients and speedo. v5: Add error message when speedo is missing.
