similar to: [PATCH 0/4] fix pmu code on gk208+

reworked this series quite a lot. Now we want the Host to configure the counters through the PMU. The series isn't complete though because it needs: 1. reordering 2. better commit messages but I felt like sending those out before doing a final version. I also found some weird register overwriting issue on the PMU I have to track down, because it interfers with the counter read out. I am

I think I am done reworking the series and getting to a point where I think it is basically finished. The configuration of the slots could be improved later on when working on dynamic reclocking, but for now it's good enough to report the current GPU utilization to userspace. Patches 1-4 imeplement PMU commands to setup and readout the counters. Patches 5-6 lets Nouveau make use of 1-4. Patch

these are usually used for dynamic reclocking on gt215 and newer The counters are used to get the load of the core, memory, video and pcie loads currently I expose the loads through a debugfs "current_load" file, but I want to move that to nvif and just add a wrapper around that in debugfs for convenience. Using nvif would have the advantage, that userspace tools can easily get loads

Re-use the therm-exported fan structure with only two minor modifications: - pwm_freq: u16 -> u32; - add fan_type (toggle or PWM) v2: - Do not memset the table to 0 as it erases the pre-set default values Signed-off-by: Martin Peres <martin.peres at free.fr> --- drm/Kbuild | 1 + drm/core/include/subdev/bios/fan.h | 1 + drm/core/subdev/bios/fan.c | 1

this series makes use of the load counters we can use to get information about the current load of the gpu. This series includes the needed pmu bits and a debugfs interface to read them out. Currently the values are between 0 and 255, because it is much easier to implement it this way on the pmu. Karol Herbst (4): subdev/pmu/fuc: add gk104 pmu/fuc: add macros for pdaemon pwr counters

fixes compilation issues with recent envytools, because movw was removed from fuc5, because it doesn't exist there anymore. The current code is most likely broken for fuc5 hardware as well and might have triggered all kinds of random memory reclocking fails. Changes in fuc3 binaries are tue do opcode optimizations using shorter opcodes when possible. Signed-off-by: Karol Herbst <kherbst

Fixes failure to compile with recent envyas as a result of the 'movw' alias being removed for v5. A bit of history: v3 only has a 16-bit sign-extended immediate mov op. In order to set the high bits, there's a separate 'sethi' op. envyas validates that the value passed to mov(imm) is between -0x8000 and 0x7fff. In order to simplify macros that load both the low and high word,

Following a series of patches that implement memory reclocking for NVA3/5/8 with DDR2, DDR3 and GDDR3 on board. I tested these patches on 6 different graphics cards, but I expect reclocking now to work on many more. Testers can pick up these patches and test it by enabling pstate (nouveau.pstate=1). They should then be able to change clocks by writing to /sys/class/drm/card0/device/pstate. Correct

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

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

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.

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." variables, like in NVE0 As always,
