We need to block the drm core from doing anything that may touch our vram during reclock, so take the drm mutex for the duration. Signed-off-by:

Touching vram while the card is reclocking can lead to lockups. Unmap any pages that could be touched by the CPU and block any accesses to vram until the reclocking is complete. Signed-off-by:

There's a moderate amount of effort involved in setting the card up for clock transitions, so unify the codepaths to make it easier to implement. Signed-off-by:

Add two new sysfs attributes: - dynpm - power_state Echoing 0/1 to dynpm disables/enables dynamic power management. The driver scales the sclk dynamically based on the number of queued fences. dynpm only scales sclk dynamically in single head mode. Echoing x.y to power_state selects a static power state (x) and clock mode (y). This allows you to statically select a power state and clock mode. Selecting a static clock mode will disable dynpm.

- pm_misc() - handles voltage, pcie lanes, and other non clock related power mode settings. Currently disabled. Needs further debugging - pm_prepare() - disables crtc mem requests right now. All memory clients need to be disabled when changing memory clocks. This function can be expanded to include disabling fb access as well. - pm_finish() - enable active memory clients. Signed-off-by:

This also simplifies the code and enables reclocking with multiple heads active by tracking whether the power states are single or multi-head capable.

Useful for certain power management operations. You need to wait for the GUI engine (2D, 3D, CP, etc.) to be idle before changing clocks or adjusting engine parameters.

After thinking it over a lot it made more sense for the core to deal with the output polling especially so it can notify X. v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings. v3: add config lock take inside polling, add intel/nouveau poll init/fini calls v4: config lock was a bit agressive, only needed around connector list reading. otherwise it could re-enter. glisse: discard drm_helper_hpd_irq_event v3: Reviewed-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: -

let vga16fb claim 0xA0000+0x10000 region as its aperture; drm drivers don't use it, so we have to detect it and kick vga16fb manually - but only if drm is driving the primary card Signed-off-by:

Currently vesafb/efifb/... is kicked when hardware driver is registering framebuffer. To do it hardware must be fully functional, so there's a short window between start of initialisation and framebuffer registration when two drivers touch the hardware. Unfortunately sometimes it breaks nouveau initialisation. Fix it by kicking firmware driver(s) before we start touching the hardware. Reported-by:

Recently I've studied my system dmesg and seen this: <lots of stuff before> 1 [ 0.478416] ACPI: Battery Slot [C1B4] (battery present) 2 [ 0.478648] ACPI: Battery Slot [C1B3] (battery absent) 3 [ 0.906678] [drm] initialized overlay support 4 [ 1.762304] Console: switching to colour frame buffer device 128x48 5 [ 1.765211] fb0: inteldrmfb frame buffer device 6 [ 1.765242] registered panic notifier 7 [ 1.765272] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 8 [ 1.765372] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled <lots of stuff after> and it was not evident who registered that panic notifier on line 6. I'd bought it as some low-level stuff needed by kernel itself, but the time was inappropriate -- too late for such things. So I had to study sources to see it was drm who was registering switch-to-fb on panic. Let's avoid possible confusion and mark this message as going from drm subsystem. (I'm a bit unsure whether to use '[drm]:' or 'drm:' -- the rest of the kernel just uses 'topic:', and even in drm_fb_helper.c we use 'fb%d:' without [] brackets. Either way is ok with me.)

Smatch complained that we initialize 6 elements in add_detailed_modes() but the timings[] array is declared with 5 elements. Adam Jackson verified that 6 is the correct number of timings.

I don't have the docs for 1.2 or earlier, but we're > paranoid enough about not adding broken timings that we should be fine. This patch is basically a clean up, because timings[] is declared inside a union and increasing the number of elements here doesn't change the overall size of the union. Signed-off-by:

Previous reset code leaded to computer hard lockup (need to unplug the power too reboot the computer) on various configuration. This patch change the reset code to avoid hard lockup. The GPU reset is failing most of the time but at least user can log in remotely or properly shutdown the computer. Two issues were leading to hard lockup : - Writting to the scratch register lead to hard lockup most likely because the write back mecanism is in fuzy state after GPU lockup. - Resetting the GPU memory controller and not reinitializing it after leaded to hard lockup. We did only reinitialize in case of successfull reset thus unsuccessfull reset quickly leaded to hard lockup. Signed-off-by:
