2022-07-18video: fbdev: atari: Remove unused definitions and variablesGeert Uytterhoeven1-20/+0
Several definitions and variables are unused. Some variables are set but further unused. Remove them. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>
2022-07-18video: fbdev: atari: Fix VGA modesGeert Uytterhoeven1-2/+2
The pixclock values in the vga and vga70 modes are wrong, as they should use the 25.175 MHz clock instead of the 32 MHz clock. Swap the left and right margins to match f25.{right,left} (struct pixel_clock declares them in a different order), and update the hsync lengths to match what the driver programs by default. Correct the (wrong) floating-point vrefresh value for the vga mode.

2022-07-18video: fbdev: atari: Fix TT High video mode vertical refreshGeert Uytterhoeven1-1/+1
The vertical refresh rate for the TT High video mode (1280x960) is wrong. Fortunately this field is not really used. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>
2022-07-18video: fbdev: atari: Remove unneeded casts to void *Geert Uytterhoeven1-2/+2
Arbitrary pointers can be passed to functions accepting "void *" without casting. Remove the casts, as they make it impossible to validate types. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>
2022-07-18video: fbdev: atari: Remove unneeded casts from void *Geert Uytterhoeven1-6/+6
There is no need to cast fb_info.par to "struct atafb_par *", as the former has type "void *". Remove the casts, as they make it impossible to validate types.

The red, green, and blue color values are 16-bit, while the external graphics hardware registers are 8-bit. Add the missing conversion from 16-bit to 8-bit.

2022-07-18video: fbdev: atari: Fix inverse handlingGeert Uytterhoeven2-5/+3
Currently, the "inverse" option does not do anything, as it just sets a flag, which is further unused. Fix this by calling fb_invert_cmaps() instead, like other drivers do. As this only affects the console colormap, this does not affect X. Update the documentation to match the actual behavior.

Vertical wrap is not supported (fb_fix_screeninfo.ywrapstep = 0), hence there is no point in setting the FB_VMODE_YWRAP flag in video modes. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Tested-by: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>
2022-07-18video: fbdev: atari: Simplify atafb_pan_display()Geert Uytterhoeven1-27/+2
The fb_pan_display() function in the core already takes care of validating the panning parameters before calling the driver's .fb_pan_display() callback, and of updating the panning state afterwards, so there is no need to repeat that in the driver.

Since segment_pages is no longer a compile time constant, it looks the DIV_ROUND_UP(node->size, segment_pages) breaks the 32b build. Simplest is just to use the ULL variant, but really we should need not need more than u32 for the page alignment (also we are limited by that due to the sg->length type), so also make it all u32.

2022-07-16random: cap jitter samples per bit to factor of HZJason A. Donenfeld1-1/+1
Currently the jitter mechanism will require two timer ticks per iteration, and it requires N iterations per bit. This N is determined with a small measurement, and if it's too big, it won't waste time with jitter entropy because it'd take too long or not have sufficient entropy anyway. With the current max N of 32, there are large timeouts on systems with a small CONFIG_HZ. Rather than set that maximum to 32, instead choose a factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for different configurations of CONFIG_HZ.
