| * drm/i915: Stop trying to use ACPI lid status to determine LVDS connection.Eric Anholt2010-03-231-51/+1
| | | | | | | | | | | | | | | | | | | | | | I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so. Better to light up an unintended panel than to not light up the only usable output on the system. Signed-off-by: Eric Anholt <eric@anholt.net> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org>
| * drm/intel: fix up set_tiling for untiled->tiled transitionDaniel Vetter2010-03-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug introduced in commit 10ae9bd25acf394c8fa2f9d795dfa9cec4d19ed6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Feb 1 13:59:17 2010 +0100 drm/i915: blow away userspace mappings before fence change The problem is that when there's no fence reg assigned and the object is mapped at a fenceable offset in the gtt, the userspace mappings won't be torn down. Which happens on untiled->tiled transition quite often on 4th gen and later because there fencing does not have any special alignment constraints (as opposed to 2nd and 3rd gen on which I've tested the original commit).

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To save the registers for all CPUs a sigp "store status" is done that stores the registers to address absolute zero. To access storage at absolute zero, normally the address of the prefix register of the accessing CPU has to be used. This does not work when large pages are active (currently only under LPAR). In order to fix that problem, instead of memcpy memcpy_real is used, which switches to real mode where prefixing works.

This leads to an inconsistent PCM pointer that is likely to result in an underrun. To work around this, read the register multiple times until we get a valid value; the error state seems to be very short-lived.

Takashi Iwai suggested that the dmap_out field of the audio_operations structure should be used instead. This is not tested.

For extended partition itself, this makes sure to use bigger size than one logical sector size at least.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to use disks larger than 2TiB on Windows XP, it is necessary to use 4096-byte logical sectors in an MBR. Although the kernel storage and functions called from msdos.c used "sector_t" internally, msdos.c still used u32 variables, which results in the ability to handle XP-compatible large disks. This patch changes the internal variables to "sector_t". Daniel said: "In the near future, WD will be releasing products that need this patch".
