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:

Permedia 2V uses its own registers to set a memory clock. The patch adds these registers and uses them in the set_memclock() function. 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:

Fontmaps can be 256 or 512 in length. The only driver that can do tileblitting can only handle 256 characters. Check for this when setting the font. Signed-off-by:

Implement fb_get_tilemax(). It just returns 256. Signed-off-by:

Antonino A. Daplas authored
Add a tile method, fb_get_tilemax(), that returns the maximum length of the tile map (or font map). This is needed by s3fb which can only handle 256 characters. 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:

Advertise that vga16fb can only handle widths that are 8-pixel-multiple only (software limitation). To ensure that a legal font is 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.

Allow the saving and restoration of VGA text mode. The state is saved on the first open and restored on the last close. Because of the VGA registers are linearly mapped to the MMIO space, MMIO access is used which is not limited to X86 platforms nor to the primary display device. An echo 0 > /sys/class/vtconsole/vtcon1/bind will convert the display from graphics to text mode. Signed-off-by:
