parisc/sticore: Avoid hard-coding built-in font charcount

2020-11-16T15:31:58+00:00

sti_select_fbfont() and sti_cook_fonts() are hard-coding the number of characters of our built-in fonts as 256. Recently, we included that information in our kernel font descriptor `struct font_desc`, so use `fbfont->charcount` instead of hard-coded values. Depends on patch "Fonts: Add charcount field to font_desc".

console: Delete dummy con_font_set() and con_font_default() callback implementations

2020-11-16T15:31:09+00:00

.con_font_set and .con_font_default callbacks should not pass `struct console_font *` as a parameter, since `struct console_font` is a UAPI structure. We are trying to let them use our new kernel font descriptor, `struct font_desc` instead. To make that work slightly easier, first delete all of their no-op implementations used by dummy consoles. This will make KD_FONT_OP_SET and KD_FONT_OP_SET_DEFAULT ioctl() requests on dummy consoles start to fail and return `-ENOSYS`, which is intended, since no user should ever expect such operations to succeed on dummy consoles.

console: Delete unused con_font_copy() callback implementations

2020-11-16T15:27:03+00:00

Recently in commit 3c4e0dff2095 ("vt: Disable KD_FONT_OP_COPY") we disabled the KD_FONT_OP_COPY ioctl() option. Delete all the con_font_copy() callbacks, since we no longer use them. Mark KD_FONT_OP_COPY as "obsolete" in include/uapi/linux/kd.h, just like what we have done for PPPIOCDETACH in commit af8d3c7c001a ("ppp: remove the PPPIOCDETACH ioctl").

Fonts: Make font size unsigned in font_desc

2020-10-28T18:40:11+00:00

`width` and `height` are defined as unsigned in our UAPI font descriptor `struct console_font`. Make them unsigned in our kernel font descriptor `struct font_desc`, too. Also, change the corresponding printk() format identifiers from `%d` to `%u`, in sti_select_fbfont().

parisc/sticon: Add user font support

2020-10-15T06:12:59+00:00

This is a major rework of the sticon (parisc text console) driver in order to support user font support. Usually one want to use the stifb (parisc framebuffer driver) which is based on fbcon and does support fonts and colors, but some old machines (e.g. HP 730 workstations) don't provide a supported stifb graphic card, and for those user fonts are preferred. This patch drops unused code for software cursor and scrollback, enhances the debug output and adds better documentation. The code was tested on various machines with byte-mode and word-mode graphic cards on GSC- and PCI-busses. Signed-off-by: Helge Deller

parisc/sticon: Always register sticon console driver

2020-10-15T06:10:39+00:00

If the ROM provides functional STI routines, always register the sticon driver, even if the serial console was choosen as boot device. Additionally, in that case, do not make the sticon driver the default output console device. Signed-off-by: Helge Deller

fbdev, newport_con: Move FONT_EXTRA_WORDS macros into linux/font.h

drivers/video/console/newport_con.c is borrowing FONT_EXTRA_WORDS macros from drivers/video/fbdev/core/fbcon.h. To keep things simple, move all definitions into . Since newport_con now uses four extra words, initialize the fourth word in newport_set_font() properly.
