I did some simple benchmarking (time cat linux-2.6.7-mm5/MAINTAINERS)
between 2.4 and 2.6 and I am not satisfied with what I see (It's claimed
that fbdev-2.6 is faster than 2.4). The reason for the claim:
2.4 putcs - draw small amounts of data a lot of times
2.6 putcs - draw larger amounts of data a fewer times
The way characters are drawn in 2.6 is optimal for accelerated drivers but
should also give a speed boost for drivers that rely on software drawing.
However the penaly incurred when preparing a large bitmap from a number of
small bitmaps is currently very high. This is because of the following
reasons:
1 fb_move_buf_{aligned|unaligned} uses pixmap->{out|in}buf. This is very
expensive since outbuf and inbuf methods process only a byte or 2 of data
at a time.
2 fb_sys_outbuf (the default method for pixmap->outbuf) uses memcpy().
Not a good choice if moving only a few bytes.
3 fb_move_buf_unaligned (used for fonts such as 12x22) also involves a
lot of bit operations + a lot of calls to outbuf/inbuf which
proportionately increases the penaly.
So, I thought of separating fb_move_buf_* to fb_iomove_buf_* and
fb_sysmove_buf_*.
fb_iomove_buf_* - used if drivers specified outbuf and inbuf methods
fb_sysmove_buf_* - used if drivers have no outbuf or inbuf methods
*Most, if not all drivers fall in the second category.
Below is a table that show differences between 2.4, 2.6 and 2.6 +
abovementioned changes. To reduce the effect of panning and
fillrect/copyarea, the scrollmode is forced to redraw.

Summary:
1 2.6 unaccelerated is a bit faster than 2.4 when handling 8x16 fonts,
with a higher speed differential at high color depths.
2 2.4 unaccelerated is a bit faster than 2.6 when handling 12x22 fonts,
with a smaller speed difference at high color depths (2.6 is actually a
bit faster than 2.4 at 32bpp).
3 2.4 rivafb accelerated suffers at high color depths, even becoming
slower than unaccelerated, possibly because of the 'draw few bytes many
times' method.
4 2.6 rivafb accelerated has similar performance at any color depth,
possibly because of 'draw lots of bytes a fewer times' method.
5 With the changes, there is a speed gain of ~1.7 seconds and ~5.7
seconds with 8x16 and 12x22 fonts respectively indepependent of the color
depth or acceleration used. The speed gain is constant but significant.
Below is a patch against 2.6.7-mm5. The effects will be very noticeable
with drivers that uses SCROLL_REDRAW, but one should still see some speed
gain even if SCROLL_YPAN/YWRAP is used.
Separated fb_sys_move_* into fb_iosys_move_* and fb_sysmove_* to reduce
penalty when constructing fb_image->data from character maps. In my
testcase (1024x768 SCROLL_REDRAW), I get a ~1.7 second advantage with 'time
cat MAINTAINERS' using 8x16 fonts and ~5.7 seconds with 12x22 fonts. The
speed gain is independent of acceleration or color depth.

Please review and apply the following patch if you find it agreeable.

The need for these changes became appearent during a code review of

The access of the list_head can be simplified by making it the first element
of the structure, thus avoiding a needless add-immediate without negatively

This is ES7000 sub arch update. The tiny patch below fixes a bug that
results in boot problem on all ES7000 partitions with numbers higher than
0. Currently, target_cpus() returns incorrect cpumask value since it
indexes bits by the logical APIC ID, not by CPU number. The patch affects
only ES7000 sub arch. It was tested extensively on the system with
multiple partitions.

- Update display->vrows when fbset changes certain fields in var (such as
color depth) but without changing the display resolution. This might
produce concommitant changes in other fields such as and especially
var->yres_virtual.
- Clear the FBINFO_MISC_MODECHANGEUSER flag _before_ issuing a
notifier_call_chain(). Clearing it after the notifier_call_chain() will
cause fbcon to go into an infinite loop.
As we've discussed in another thread, below is a diff that will do a set_par()
as late as possible when there is KD_TEXT<->KD_GRAPHICS switch. The set_par()
will be forced in fbcon_resize() instead.
Not sure if this has repercussions with the other drivers, but this patch
fixed the X nv driver hanging when switching to the console. (I believe the
crash is actually caused by an early set_par() -- while in fbcon_blank.
Removing the set_par in fbcon_blank fixed the hang but caused cursor sprite
and display corruption).
1 Seems that nVidia hardware has a limit on clipping coordinates that is
also dependent on the color depth of the framebuffer.
2.From Pawel Goleniowski <pawelg@dabrowa.pl>: Fix for wrong colors at 16bpp
(RGB565). The fix has been submitted several times in lkml and this list
but was never applied.
3 Search all I2C/DDC busses for the EDID block instead of just the first
bus.
4 Updated request_mem_region/release_mem_region to
pci_request_regions/pci_release_regions.
