2010-05-18drm: move radeon_fixed.h to shared drm_fixed.h headerBen Skeggs
Will be used by nouveau driver also in the near future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Enable memory reclocking on r100-500Matthew Garrett
This seems to be relatively stable now, so enable it for these chipsets too. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Try harder to ensure we reclock in vblankMatthew Garrett
The vblank interrupt on r600 doesn't seem to be especially reliable, so perform some sanity checks before the actual reclock. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Fix locking in power management pathsMatthew Garrett
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Make sure that we determine the correct PM state before transitionMatthew Garrett
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Enable memory reclockong on r600Matthew Garrett
With luck, dynamic memory reclocking on r600 should be stable with the previous patches. Enable it. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Stop the ttm workqueue while reclockingMatthew Garrett
The ttm bo workqueue may touch objects while we're reclocking, so make sure it's blocked until we're done. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18ttm: Provide an API for starting and stopping the delayed workqueueMatthew Garrett
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Take drm struct_mutex over reclockingMatthew Garrett
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Unmap vram pages when reclockingMatthew Garrett
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 <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Unify PM entry pathsMatthew Garrett
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18drm/radeon/kms/pm: rework power managementAlex Deucher
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.

2010-05-18drm/radeon/kms/pm: add additional asic callbacksAlex Deucher
- 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.

2010-05-18drm/radeon/kms/pm: add asic specific callbacks for getting power state (v2)Alex Deucher
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.).

2010-05-18fbmem, drm/nouveau: kick firmware framebuffers as soon as possibleMarcin Slusarz
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.

2010-05-18drm: Prefix info printk about registering panic notifier with 'drm'Kirill Smelkov
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.)

2010-04-27drm/radeon/kms: R3XX-R4XX fix GPU reset codeJerome Glisse
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.
