Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.
For more info regarding lifetime rule cleanup, please read the
following message.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
Compile tested with make all{yes,mod}config on x86_64 and i386.

In the PCI + hotplug case we end up with some bogus references between
the PCI driver path and the DC path. In order to fix this, we have to
rework the common init path for __devinit, as well as moving all of the
data that it references to __devinidata.
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
A few minor things were broken here. fix and var screeninfo should have
been __devinitdata, board_list[] gets renamed to board_driver[] so the
modpost matching does the right thing, and we properly discard some of
the unused exit sections.

After loading output.ko and video.ko, you would have

For example, I got acpi_video0, acpi_video1,acpi_video2,and acpi_video3
under /sys/class/video_output on my T40.
I can query the status of output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device). Also you can turn off video1 and turn on
video0 by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC B.5.7 _DSS for the parameter definition.
Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.

Reported by James Pearson as:
boot to run level 3
if not root, then make sure /dev/console is writeable
login and type:
setterm -blank 0
start X
type into an xterm:
while true; do echo "" > /dev/console; usleep 100000; done
while the above loop is running switch to the text console and back
again (Ctrl-Alt-F1 then Ctrl-Alt-F7)
... and the screen will be shifting (and wrapping) to the left.
This problem stems from continuously writing text to the system console (which
is in KD_TEXT mode) while the foreground console is in KD_GRAPHICS
mode. Somewhere along the way, console printing got confused and omitted the
KD_GRAPHICS/KD_TEXT test. Thus, vgacon attempted to scroll the screen of X,
which causes X to shift.
Fix by disallowing vgacon to touch the hardware when the vc is in KD_GRAPHICS
mode. A definitive fix entails a full audit of the console code.

This is usually documented as needed for access AR01-AR0F,
but on ARK Logic card it is needed for AR10 (otherwise read
returns some nonsence and save_vga_text() returns before do
anything).
2) do not restore AR10, because it was not changed during
3) remove modification of misc reg:
/* force graphics mode */
vga_w(state->vgabase, VGA_MIS_W, misc | 1);
as comment is misleading - LSB of misc reg does not set/reset graphics
mode, but set color/mono adresses of CRT and some other regs.
but these regs are not used during save/restore fonts.
(it worked even when (misc | 1) was replaced by (misc & ~1) ).

Check if the mode can properly display the screen. This will be needed by
drivers where the capability is not constant with each mode. The function
fb_set_var() will query fbcon the requirement, then it will query the driver
(via a new hook fb_get_caps()) its capability. If the driver's capability
cannot handle fbcon's requirement, then fb_set_var() will fail.
For example, if a particular driver supports 2 modes where:
mode1 = can only display 8x16 bitmaps
mode2 = can display any bitmap
then if current mode = mode2 and current font = 12x22
fbset <mode1> /* mode1 cannot handle 12x22 */
fbset will fail

A few drivers are not capable of blitting rectangles of any dimension.
vga16fb can only blit 8-pixel wide rectangles, while s3fb (in tileblitting
mode) can only blit 8x16 rectangles. For example, loading a 12x22 font in
vga16fb will result in a corrupt display.
Advertise this limitation/capability in info->pixmap.blit_x and blit_y. These

width/height of 7+1 is supported.

framebuffer. Implementing this will allow the "framebuffer" to be accesible
from user space via mmap().

Fill transp->msb_right with the correct value. fbcon ignores this, but user
apps may not.

show_pan will display the value of the xoffset twice, instead of the xoffset
and yoffset. Fix.

Make nvidiafb use fb_ddc_read(). This patch was submitted before but was
reverted due to problems in a non-x86 platform. This includes a fix for that
where ddc reading is bypassed if there is no DDC bus (duh).

If there is less than RING_MIN_FREE available in the ring buffer,
dinfo->ring_space is set to a big value forcing wait_ring to return.
Fix by making ring space = 0 if ring space < RING_MIN_FREE.

This particular monitor does not have a limits block and has only one set of
monitor timings. Fix by adding a limits block to the EDID and extend the
horizontal sync frequency range to 30 kHz and 75 Khz.

Add the new display class. This is meant to unite the various solutions to
display units ie acpi output device, auxdisplay and the defunct lcd class
in the backlight directory.

I have a problem with blanking. The soundcard uses speakers of the monitor.
Sound is muted when the screen blanks due to a bug in aty128fb.c.
Here is a fragment of linux/fb.h
/* VESA Blanking Levels */
#define VESA_NO_BLANKING 0
#define VESA_VSYNC_SUSPEND 1
#define VESA_HSYNC_SUSPEND 2
#define VESA_POWERDOWN 3
enum {
/* screen: unblanked, hsync: on, vsync: on */
FB_BLANK_UNBLANK = VESA_NO_BLANKING,
/* screen: blanked, hsync: on, vsync: on */
FB_BLANK_NORMAL = VESA_NO_BLANKING + 1,
/* screen: blanked, hsync: on, vsync: off */
FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1,
/* screen: blanked, hsync: off, vsync: on */
FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1,
/* screen: blanked, hsync: off, vsync: off */
FB_BLANK_POWERDOWN = VESA_POWERDOWN + 1
};
So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2,
FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4.
And now:
blank = FB_BLANK_NORMAL (1)
blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true,
so normal blank caused hsync suspend and sound is muted.
