The problem affects nv40 cards during booting. It comes from there being two places where subdev arrays are maintained. A commit was recently added to make the two equal. However, the struct nouveau_device version ends up being referenced before it is initialized. The problem arises during the creation of the INSTMEM and THERM subdevs. ' Signed off by: Bob Gleitsmann rjgleits at bellsouth.net

Second version of the gk20a clock patches. I have tried to keep the therm and volt devices mandatory in the clock driver, but unfortunately they are too tied to bios to allow this, at least for the moment. Consequently this version is mostly a port of the first version to Ben's tree. Ben, please let me know what I have done wrong in terms of integration to your tree, as the main purpose of

Hi, This series includes some pieces of fixes to complete the GK20A power on/off sequences and add the suspend/resume support. The patches 1/11 - 4/11 are based on the linux-next-20141219. The patches 5/11 - 11/11 are based on the branch "linux-3.19" of Ben Skeggs's tree (http://cgit.freedesktop.org/~darktama/nouveau). Thanks, Vince Vince Hsu (4): (linux-next-20141219) ARM:

Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to, and can trick

Greetings, After the modesetting commit, I have been unable to compile xf86-video-nouveau. The git site for drm given on the wiki page does not get the proper xf86drmMode.h, etc. I noted that libdrm git has over 100 branches and I really don't want to try all of them. Fedora 9 has a patch of the libdrm source rpm that includes an earlier version of xf86drmMode.h but it's now out of

Changes since v3: - Use a single dma_attr for all DMA-API allocations in instmem instead of one per allocation - Use device.info.ram_size instead of pfb->ram to check whether VRAM is present outside of nvkm Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into

A series I have waited too long to submit, and the recent refactoring made me pay the price of my perfectionism, so here are the features that are at least completed Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to,

Thanks Ilia for the v2 review! Here is the v3 of this IOMMU support for GK20A series. Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove

Hi, This is a try to have some simple DVFS (Dynamic Voltage and Frequency Scaling) support for GK20A. Instead of relying on other existing frequency scaling framework, we create a simple subdev in Nouveau for the same purpose. That's because we don't want to make the DVFS implementation for GK20A far more than enough in the beginning and hinder the implementation for dGPU in the future.

We will use this subdev to disable temperature reading on cards that did not get a sensor calibration in the factory.

Current uninitialized sensor detection does not work for me on nv4b and sensor returns crazy values (>190?C). It stabilises later, but it's too late - therm code shutdowns the machine... Let's just reset it on init. Signed-off-by: Marcin Slusarz <marcin.slusarz at gmail.com> --- drivers/gpu/drm/nouveau/core/subdev/therm/nv40.c | 12 +++++++++++- 1 file changed, 11
