Tighten the use of return values from the target map and end_io functions. Values of 2 and above are now explictly reserved for future use. There are no existing targets using such values. The patch has no effect on existing behaviour. o Reserve return values of 2 and above from target map functions. Any positive value currently indicates "mapping complete", but all existing drivers use the value 1. We now make that a requirement so we can assign new meaning to higher values in future. The new definition of return values from target map functions is: < 0 : error = 0 : The target will handle the io (DM_MAPIO_SUBMITTED). = 1 : Mapping completed (DM_MAPIO_REMAPPED). > 1 : Reserved (undefined). Previously this was the same as '= 1'. o Reserve return values of 2 and above from target end_io functions for similar reasons. DM_ENDIO_INCOMPLETE is introduced for a return value of 1. Test results: I have tested by using the multipath target. I/Os succeed when valid paths exist. I/Os are queued in the multipath target when there are no valid paths and queue_if_no_path is set. I/Os fail when there are no valid paths and queue_if_no_path is not set. Signed-off-by:Kiyoshi Ueda <k-ueda@ct.jp.nec.com> Signed-off-by:

Change the interface of dm_suspend() so that we can pass several options without increasing the number of parameters. The existing 'do_lockfs' integer parameter is replaced by a flag DM_SUSPEND_LOCKFS_FLAG. There is no functional change to the code. Test results: I have tested 'dmsetup suspend' command with/without the '--nolockfs' option and confirmed the do_lockfs value is correctly set. Signed-off-by:

The existing code allocates an extra slot in bi_io_vec[] and uses it to store the region number. This patch hides the extra slot from bio_add_page() so the region number can't get overwritten. Also remove a hard-coded SECTOR_SHIFT and fix a typo in a comment. Signed-off-by:

Automatically set VIDEO_SELECT when you select VESA FB. Currently if you select VESA FB with fbcon but don't select VGA console the box will not have its video mode set. Thus you get a blank screen. Signed-off-by:

We cannot assume that the BIOS will be correctly setting up the hardware, so set some bits in various display registers to enable video output. Allow an advanced user to specify a frambuffer size, rather then probing the BIOS. All of these fixes were prompted by the OLPC effort. [akpm@osdl.org: cleanups] Signed-off-by:

ACPI drivers like ibm-acpi are moving to the backlight sysfs infrastructure. During ibm-acpi testing, I have noticed that backlight_device_unregister() sets the display brightness and power to zero. This causes the display to be dimmed on ibm-acpi module removal. It will affect all other ACPI drivers that are being converted to use the backlight class, as well. It also affects a number of framebuffer devices that are used on desktops and laptops which might also not want such behaviour. Since working around this behaviour requires undesireable hacks, Richard Purdie decided that we would be better off reverting the changes in the sysfs class, and adding the code to dim and power off the backlight device to the drivers that want it. This patch is my attempt to do so. Patch against latest linux-2.6.git. Changes untested, as I lack the required hardware. Still, they are trivial enough that, apart from typos, there is little chance of getting them wrong. Signed-off-by:

Fix some possible unaligned accesses when accessing fields of 'image' pointer. Indeed this pointer was obtained by allocating a block of memory that embeds a temporary array plus an image structure. The temporary buffer was located at the start of the allocated block and depending on its size, the image structure which comes right after can be unaligned. For example when using mini fonts (4x6) (cursor's width is 4 and its height is 6) the temporary buf size is 6 bytes. Therefore this patch moves the image structure to the start of the block and moves the temporary buffer right after. It makes 'image' pointer always aligned and since the tempo buf is a buffer of char, it's always correctly aligned as well. It also fixes the file header alignement. Signed-off-by:

Some register were only set in aty_init() which is not called on resume. I added the aty_resume_chip() function to reset those registers on resume. Susped-to-ram now works on a HP Omnibook 6000 with acpi_sleep=s3_bios. Signed-off-by:

This patch adds a way to create and use the video plane (YUV overlay) and scaling video scaling features of the chip. The overlay is configured, resized and modified using a device specific ioctl. Also included in this patch: - If no platform data was passed, print an error and exit instead of crashing. - Added a write_reg(_dly) macro. This improves readability when manipulating chip registers. (no more udelay() after each write). - Comments about some issues. Signed-off-by: -

This patch fixes debugfs for mbxfb and adds some missing registers. The way registers were read was out of sync with the rest of the driver (direct access instead of using readl()) sdram controller registers are now accessible in the sdram/ subdirectory and some other registers are grouped in the misc/ subdirectory.
