6.2 x86_64 "mtrr_cleanup: can not find optimal value"
...essages finally ending with "mtrr_cleanup: can not find optimal value" and "please specify mtrr_gran_size/mtrr_chunk_size". I have been searching around and reading the kernel docs but are bit lost on the impact. The system CPU is a q6600 so it supports mtrr. It has 8gb of RAM and a G33 intel chipset (maximum memory is 8gb), 256mb onboard Intel video. Problem exists with DVD 6.2 kernel and latest in yum update 2.6.32-220.7.1.el6.x86_64. If I disable the Bios "memory remap feature", mtrr appears to have found it settings. But it says total ram covered is 741...

NVA3: Small misc mem reclocking fixes
Patch 1 fixes nva3 bailing due to not finding the right ramcfg Patch 2 is a resend rebased on 3.17.0-rc4 for setting the vblank period Patch 3-5 handle writes to per-partition registers, for which NVA3 does not have special broadcast regs available. Patch 6 removes local structs from NVA3 reclocking in favour of the already existing "ram->base.&quot...

Implement reclocking for DDR2, DDR3, GDDR3
...y enabling pstate (nouveau.pstate=1). They should then be able to change clocks by writing to /sys/class/drm/card0/device/pstate. Correct values can be read from this sysfs node. Note that this API is likely to change in the future, hence it's hidden behind this kernel parameter. What works: - Reclocking on many DDR2, DDR3 and GDDR3 cards, both up and down - Doing so "invisibly", eg no black screens What still needs fixing: - GDDR5. There's non-reclocking related issues with GDDR5 cards in this family. Sorry, Michael.. - Link training is only done for a...

Preparations for Fermi DRAM clock changes
No, no, these will not implement Fermi reclocking. This set of patches contains some of the preparatory work that I deem stable enough to move upstream. Notable changes - Training pattern upload routines from GK104+ now shared with GT215+ - Timing calculation for Fermi - GDDR5 MR calculation from VBIOS timing table v1.0. Also useful for that pesky GT 240. - A routine to translate a VBIOS init

OS does not see all my RAM
My BIOS shows all my RAM, but when I boot up linux it does not see all the RAM I have two one GIG sticks of RAM, which show up in my bios, but when typing free, I see that it only shows 256Megs. Is there a way to specify the amount of RAM if linux cannot detect this, or how can I fix/tweak the OS to recognize the...

[PATCH 1/6] make RAM device optional
Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the long-term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in place...

[RFC] Fermi/Kepler identify DLLoff
Hello, Attached a small patch that correctly identifies the DLLoff bit for >=GF100. Marked RFC because I haven't seen any GDDR5 samples that *enable* the DLL. I'd like to verify whether the DLL should be reset when enabled. Could increase likelihood of succesfull reclock. Ben: could you do some experiments with this bit to see if GDDR5 needs some DLL reset logic? Thanks, and happy

RESEND Preparations for Fermi DRAM clock changes
Two patches went missing as a result of PEBCAK. No v2 marks as nothing changed really. Just resending for easier enforcement of patch order in other people's trees. Sorry for the noise. Original message: No, no, these will not implement Fermi reclocking. This set of patches contains some of the preparatory work that I deem stable enough to move upstream.
