DRM: i915: add mode setting support This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

drm/i915: framebuffer compression for pre-GM45 This patch adds framebuffer compression (good for about ~0.5W power savings in the best case) support for pre-GM45 chips. GM45+ have a new, more flexible FBC scheme that will be added in a separate patch. FBC can't always be enabled: the compressed buffer must be physically contiguous and reside in stolen space. So if you have a large display and a small amount of stolen memory, you may not be able to take advantage of FBC. In some cases, a BIOS setting controls how much stolen space is available. Increasing this to 8 or 16M can help. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

drm/i915: Ensure that while(INREG()) are bounded (v2) Add a new macro, wait_for, to simplify the act of waiting on a register to change state. wait_for() takes three arguments, the condition to inspect on every loop, the maximum amount of time to wait and whether to yield the cpu for a length of time after each check. v2: Upgrade failure messages to DRM_ERROR on the suggestion of Eric Anholt. We do not expect to hit these conditions as they reflect programming errors, so if we do we want to be notified.

drm/i915: Rename intel_output to intel_encoder. The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors.

drm/i915: Change I2C api to pass around i2c_adapters The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo.

drm/i915: implement drmmode overlay support v4 This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions.

drm/i915: framebuffer compression for pre-GM45 This patch adds framebuffer compression (good for about ~0.5W power savings in the best case) support for pre-GM45 chips. GM45+ have a new, more flexible FBC scheme that will be added in a separate patch. FBC can't always be enabled: the compressed buffer must be physically contiguous and reside in stolen space. So if you have a large display and a small amount of stolen memory, you may not be able to take advantage of FBC. In some cases, a BIOS setting controls how much stolen space is available. Increasing this to 8 or 16M can help. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

drm/i915: add dynamic clock frequency control There are several sources of unnecessary power consumption on Intel graphics systems. The first is the LVDS clock. TFTs don't suffer from persistence issues like CRTs, and so we can reduce the LVDS refresh rate when the screen is idle. It will be automatically upclocked when userspace triggers graphical activity. Beyond that, we can enable memory self refresh. This allows the memory to go into a lower power state when the graphics are idle. Finally, we can drop some clocks on the gpu itself. All of these things can be reenabled between frames when GPU activity is triggered, and so there should be no user visible graphical changes.

DRM: i915: add mode setting support This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces.

drm/i915: Rename intel_output to intel_encoder. The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors.

drm/i915: Use the correct scanout alignment for fbcon. This fixes a potential modesetting error during boot with plymouth on Broadwater and Crestline introduced with 9df47c. The framebuffer was hard-coding an alignment of 64K, but the modesetting code required the documented alignment of 128K.

drm/fb: fix fbdev object model + cleanup properly. The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work. This patch a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs. b) migrated all the fb helper functions out of the crtc helper file into the fb helper file. c) pushed the fb probing/hotplug control into the driver d) makes the surface sizes into a structure for ease of passing This changes the intel/radeon/nouveau drivers to use the new helper.

drm/i915: implement drmmode overlay support v4 This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions. Changes since v4: - fix up cache flushing of overlay memory regs. - killed require_pipe_a logic - it hangs the chip.
