similar to: [Bug 76475] New: Nouveau fails to load due to unknown opcode 0x80

There appear to be a crop of new hardware where the vbios is not available from PROM/PRAMIN, but there is a valid _ROM method in ACPI. The data read from PCIROM almost invariably contains invalid instructions (still has the x86 opcodes), which makes this a low-risk way to try to obtain a valid vbios image.

Hi, same for me. The screen does not freeze anymore and the boot succeeds. But now I have this kernel message during boot (for the second card): [ 24.382045] pci_pm_runtime_suspend(): nouveau_pmops_runtime_suspend+0x0/0xe0 [nouveau] returns -22 Do you want to have the complete dmesg log? I think this is a new bug. Your patch works for the previous one, so you can close it. Yours, Claas On

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). An older (obsolete) patch for the first issue was tested by the reporter: https://bugzilla.kernel.org/show_bug.cgi?id=104791#c11 (it is replaced by "check for function 0x1B

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). See the first version[1] for a background on the fixed problems. This is the second revision of incorporating feedback from Emil Velikov (patch 1), Mika Westerberg (patch 4).

Hi, Here are two patches to fix an issue reported on kernel bugzilla (infinite loop due to unchecked function) and a more important fix to fix hanging Optimus machines when runtime PM is enabled (with pm/pci patches). These are the final patches targeting v4.8. Changes compared to v2[1]: collected R-b from Hans and Mika and fixed a minor comment style issue. I recommend it to be merged before

Hello, I have an Asus laptop, U36SD, with Optimus technology. The discrete gpu is an NVIDIA GeForce GT 520M with 1GB DDR3 VRAM Using Fedora 17; up to kernel 3.3.7-1 I was able to use bumblebee and bbswitch and then running optirun command (as I could do in F16). No more with kernel 3.4. Tried 3.4.0-1.fc17.x86_64, 3.4.2-4.fc17.x86_64 and 3.4.3-1.fc17.x86_64. I already opened a bug against F17:

Do not unconditionally invoke function 0x1B without checking for its availability, it leads to an infinite loop on some firmware.

While working on a vga_switcheroo handler for Apple's Macbook Pros I stumbled upon a few bugs regarding the usage of nouveau with other switcheroo handlers and module unloading, here are my fixes for them.

Hello all, this series includes a wide range of fixes - from a few month's old one-liners from Andreas Heider regarding vga_switcheroo, via a null pointer dereference and double memory allocation, to a buffer overflow.
