* drm/i915: framebuffer compression for pre-GM45Jesse Barnes2009-09-105-19/+382
| | | | | | | | | | | | | | | 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: generate a KMS uevent at lid open/close timeJesse Barnes2009-09-101-0/+2
| | | | | | | | | | With all the other lid pieces in place, it's easy to generate a uevent for the LVDS connector just like we do for other outputs. Should make lid open/close fit in with the rest of a userland based output reconfiguration scheme. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
* drm/i915: use ACPI LID status for LVDS ->detect hookJesse Barnes2009-09-101-3/+9
| | | | | | | | | | | We can't load or hotplug detect LVDS like we can other outputs, but if there's a lid device present we can use it as a proxy. This allows the LFP state to be determined at ->detect time, making configurations requiring manual intervention today "just work" assuming the lid device status is correct.

* drm/i915: force mode set at lid open timeJesse Barnes2009-09-104-0/+28
| | | | | | | | | | | | Some laptop platforms will disable pipes and/or planes at lid close time and not restore them when the lid is opened again. So catch the lid event, and if the lid was opened, force a mode restore. Fixes fdo bug #21230.

* ACPI button: provide lid status functionsJesse Barnes2009-09-102-2/+53
| | | | | | | | | | | Some drivers need to know when a lid event occurs and get the current status. This can be useful for when a platform firmware clobbers some hardware state at lid time, and a driver needs to restore things when the lid is opened again.

* drm/i915: Write zero to DPLL_MD Reg for non-SDVO outputZhao Yakui2009-09-101-2/+5
| | | | | | | | | | | | | When the output device is LVDS, maybe the pixel clock of adjusted_mode will be less than that in mode. In such case it will set the incorrect multipler factor in DPLL_MD register.

We will add the following property for the SDVO-TV enhancements if they are supported: * Contrast/Brightness/Saturation/Hue. * left/right/top/bottom margin: This is implemented by using the horizontal/vertical overscan enhancements. When the overscan enhancements are supported, the above properties will be added.

After a short while, no IR IRQ events occur and the context control register does not react anymore. This happens regardless whether both IR DMA contexts are dual-buffer or one is dual-buffer and the other packet-per-buffer. This can be worked around by disabling dual buffer DMA mode entirely. http://sourceforge.net/mailarchive/message.php?msg_name=4A7C0594.2020208%40gmail.com (Reported by Samuel Audet.) In another report (by Jonathan Cameron), an FW643 works OK with two cameras in dual buffer mode. Whether this is due to different chip revisions or different usage patterns (different video formats) is not yet clear. However, as far as the current capabilities of firewire-core's isochronous I/O interface are concerned, simply switching off dual-buffer on non-working and working FW643s alike is not a problem in practice. We only need to revisit this issue if we are going to enhance the interface, e.g. so that applications can explicitly choose modes.

As David Moore noted, a previously correct sizeof() expression became wrong since the commit changed its argument from an array to a pointer. This resulted in an oops in ohci_cancel_packet in the shared workqueue thread's context when an isochronous resource was to be freed.

But blk_queue_max_sectors() differs a bit 1. It sets both max_sectors_kb, and max_hw_sectors_kb 2. Never allows one to change max_sectors_kb above BLK_DEF_MAX_SECTORS. If one specifies a value greater then max_hw_sectors is set to that value but max_sectors is set to BLK_DEF_MAX_SECTORS I am not sure whether blk_queue_max_sectors() should be changed, as it seems to be that way for a long time. And there may be callers dependent on that behaviour. This patch simply reverts to the older way of directly assigning the value to max_sectors as it was before.

But in some cases sk_free() is called earlier, usually after other alloc errors. Fix is to move sk_wmem_alloc initialization from sock_init_data() to sk_alloc() itself.

High order allocation is likely to fail and should always be avoided. The patch fixes this problem by replacing the original order-6 pci_alloc_consistent() with an array of order-1 pages from a pci pool. This utilized the ipw2200 DMA command blocks (up to 64 slots). The maximum firmware size support remains the same (64*8K).
