Falcon processors are used in various places of GPU chips. Although there exist different versions of the falcon, and some variants exist, the base set of actions performed on them is the same, which results in lots of duplicated code. This patch consolidates the current nvkm_falcon structure and extends...

After upgrading from 2.6.28.10 to 2.6.29.3 I've saw following new errors in kernel log: May 12 14:46:41 falcon-cl5 May 12 14:46:41 falcon-cl5 (6757,7):ocfs2_read_locked_inode:466 ERROR: status = -22 Only one node is mounted volumes in cluster: /dev/sde on /home/apache/users/D1 type ocfs2 (rw,_netdev,noatime,heartbeat=local) /dev/sdd on /home/apache/users/D2 type ocfs2 (rw,_netdev,noatime,heartbeat=local...

...step of the secure boot refactoring - as Ben asked for some fixes, I now submit it as its own series to make it easier to review (and also because rebasing secure boot on top of this takes time and I don't want to do it until this is validated!). This series attempts to factorize the duplicate falcon-related code into a single library, using the existing nvkm_falcon structure as a basis. Note that this currently makes struct nvkm_falcon used for two different purposes: this fact is acknowledged, and temporary. It just makes it easier to review this first step. Using the library, falcons are no...

Hi, the system fails to initialize your vbios using secureboot (i had a rare chance to on my system to witness it again), for now i traced it to acr_boot_falcon() in "linux/drivers/gpu/drm/nouveau/nvkm/falcon/msgqueue_0148cdec.c" where it throws -110 which is -ETIMEDOUT. You could try to increase the timeout and see if it helps something, similar to the following: diff --git a/drivers/gpu/drm/nouveau/nvkm/falcon/msgqueue.c b/drivers/gpu/drm/nou...

Hi, all. Below is a link to a brief document describing some changes in NVIDIA Falcon processors ("fuc", in Nouveau-speak, IIUC) that happened in Maxwell: certain aspects of the chip will only be available to Falcon firmware images signed by NVIDIA. So far, the set of restricted things is pretty small, but I expect this list will slowly grow over future hardware generatio...

...SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result. Alexandre Courbot (15): secboot: allow to boot multiple falcons secboot: pass instance to LS firmware loaders secboot: let LS post_run hooks return error secboot: start LS firmware in post-run hook secboot/gm20b: specify MC base address as argument secboot: add GP10B support msgqueue: support for GP10B PMU firmware fifo: add GP10B support fb: a...

Sending things in a smaller chunks since it makes their reviewing easier. This part part 2/3 of the secboot refactoring/PMU command support patch series. Part 1 was the new falcon library which should be merged soon now. This series is mainly a refactoring/sanitization of the existing secure boot code. It does not add new features (part 3 will). Secure boot handling is now separated by NVIDIA firmware versions, and LS firmwares are also loaded and managed in their own sour...

I have an XP home (falcon) and an XP pro (tatooine) machine, both behind a rh9 box (hoth) acting as firewall. I've been trying to get samba set up on the linux box. I think I have it mostly working except that the XP boxes won't list hoth under "My Network Places - Microsoft Windows Network - MSHOME", and...

On GM20x and later GPUs, firmware for some essential falcons (notably FECS) must be authenticated by a NVIDIA-produced signature and loaded by a high-secure falcon in order to access certain registers, in a process known as Secure Boot. Secure Boot requires the building of a binary blob containing the firmwares and signatures of the falcons to be loaded. T...

...he firmwares in question are not available yet I cannot send the code for them yet, but hopefully the gain in clarity will be enough to merge this series ahead of the rest. Patch 1 is just to make nv*_printk() more tolerent of my use of const pointers. Patch 2 lays the foundation of a small common falcon library that could avoid duplicated code in various parts of the driver. Right now only secure boot makes use of it (patch 3), but there are many potential users (GR, PMU, etc). I will test users and send further patches making use of it. Patch 4 renames a hook to something better describing its a...
