The vblank interrupt on r600 doesn't seem to be especially reliable, so perform some sanity checks before the actual reclock. Signed-off-by:

The ttm code could take vram_mutex followed by cp_mutex, while the reclocking code would do the reverse. Hilarity could ensue. Signed-off-by:

We need to choose the correct PM state to transition into before starting the actual change. Call radeon_get_power_state() at the top of the clock setting to do so. Signed-off-by:

With luck, dynamic memory reclocking on r600 should be stable with the previous patches. Enable it. Signed-off-by:

The ttm bo workqueue may touch objects while we're reclocking, so make sure it's blocked until we're done. Signed-off-by:

We want to be able to prevent the delayed workqueue from changing state while we're reclocking, so add an API to block and unblock it. Signed-off-by:

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:

Matthew Garrett authored
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. Eventually, we will want to select a power state based on external factors (AC/DC state, user selection, etc.). (v2) Update for evergreen Signed-off-by:

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. (v2) Fix gui idle enable on pre-r6xx asics (v3) The gui idle interrrupt status bit is permanently asserted on pre-r6xx chips, but the interrrupt is still generated. workaround it in the driver. (v4) Add support for evergreen Signed-off-by:

Check to see if the GUI engine and related blocks (2D, 3D, CP, etc) are idle or not. There are a number of cases when we need to know if the drawing engine is busy. Signed-off-by:

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.)
