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 bitmapthen if current mode = mode2 and current font = 12x22
fbset /* mode1 cannot handle 12x22 */
fbset will failSigned-off-by: Antonino Daplas

If the chip locks up, we get into a long polling loop,
where the softlockup detector kicks in.
See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=151878
for an example.[adaplas]
Chip lockup can occur at 3 points (flush, sync, and wait). Consolidate and
allow the driver to go to safe mode cleanly.Signed-off-by: Dave Jones

This patch adds restrictions to calculations of m, n and p factors
which sets the pixclock for the Permedia 2V. I found during tests
that synchronization is unstable if m (divisor) is bigger than
half of the n (numerator). The patch disallows such settings

Some drivers may reset the var->activate field on fb_check_var(). This can
lead to undefined behavior. For example, doing fbset -a with vga16fb
will only modify the active console instead of modifying all.Signed-off-by: Antonino Daplas

Fontmaps can be 256 or 512 in length. The only driver that can do tileblitting

If tileblitting is enabled (text mode), the hardware can only accept 8x16

fbcon_set_font() will now check if the new font dimensions can be drawn by the
driver (by checking pixmap.blit_x and blit_y). Similarly, add 2 new
parameters to get_default_font(), font_w and font_h, to further aid in the
font selection process.Signed-off-by: Antonino Daplas

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
fields are 32-bit arrays (font max is 32x32 only), ie, if bit 7 is set, then
width/height of 7+1 is supported.Signed-off-by: Antonino Daplas

The functions fb_read() and fb_write in fbmem.c assume that the framebuffer
is in IO memory. However, we have 3 drivers (hecubafb, arcfb, and vfb)
where the framebuffer is allocated from system RAM (via vmalloc). Using
__raw_read/__raw_write (fb_readl/fb_writel) for these drivers is
illegal, especially in other platforms.Create file read and write methods for these types of drivers. These are
named fb_sys_read() and fb_sys_write().Signed-off-by: Antonino Daplas

The generic drawing functions (cfbimgblt, cfbcopyarea, cfbfillrect) assume
that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb,
arcfb, and vfb) where the framebuffer is allocated from system RAM (via
vmalloc). Using _raw_read/write and family for these drivers (as used in
the cfb* functions) is illegal, especially in other platforms.Create 3 new drawing functions, based almost entirely from the original
except that the framebuffer memory is assumed to be in system RAM.
These are named as sysimgblt, syscopyarea, and sysfillrect.Signed-off-by: Antonino Daplas
