1) sets 'palette access disabled' during read from AR10. 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) ). Signed-off-by:Ondrej Zajicek <santiago@crfreenet.org> Signed-off-by:

Implement fb_get_caps(). This will allow the driver to tell upper layer that it can only support 256 8x16 bitmaps when in tileblitting mode (var->bits_per_pixel == 0); Signed-off-by:
-
Antonino A. Daplas authored
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 Signed-off-by:

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:

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 combination. Signed-off-by:

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

If tileblitting is enabled (text mode), the hardware can only accept 8x16 bitmaps. Advertise this to the upper layer. And to ensure that an appropriate font is always available, select an 8x16 font in Kconfig. Signed-off-by:

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:

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 A. Daplas authored
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:

It is unnecessary to pass struct file to fb_read() and fb_write() in struct fb_ops. For consistency with the other methods, pass struct fb_info instead. Signed-off-by:

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.
