VT: Add height parameter to con_font_get/set consw operations

2023-01-19T15:28:56+00:00

The current con_font_get/set API currently hardcodes a 32-pixel-tall limitation, which only dates from the old VGA hardware which could not handle taller fonts than that. This change just adds a vpitch parameter to release this constraint. Drivers which do not support vpitch != 32 can just return EINVAL when it is not 32, font loading tools will revert to trying 32 and succeed. This change makes the fbcon driver consider vpitch appropriately, thus making it able to load large fonts.

parisc/stifb: Keep track of hardware path of graphics card

2022-06-04T13:47:03+00:00

Keep the pa_path (hardware path) of the graphics card in sti_struct and use this info to give more useful info which card is currently being used. Signed-off-by: Helge Deller Cc: stable@vger.kernel.org # v5.10+

parisc/sticon: fix reverse colors

2021-11-17T10:04:02+00:00

sticon_build_attr() checked the reverse argument and flipped background and foreground color, but returned the non-reverse value afterwards. Fix this and also add two local variables for foreground and background color to make the code easier to read. Signed-off-by: Sven Schnelle Cc: Signed-off-by: Helge Deller

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

sticon: remove no-op sticon_set_origin()

2020-09-16T12:37:50+00:00

We don't need to call vc->vc_sw->con_set_origin() from set_origin() if it is no-op. Signed-off-by: Tetsuo Handa Link: https://lore.kernel.org/r/20200915000019.3422-2-penguin-kernel@I-love.SAKURA.ne.jp Signed-off-by: Greg Kroah-Hartman

vt: make vc_data pointers const in selection.h

2020-08-18T11:45:20+00:00

There are many functions declared in selection.h which only read from struct vc_data passed as a parameter. Make all those uses const to hint the compiler a bit. Signed-off-by: Jiri Slaby Link: https://lore.kernel.org/r/20200818085706.12163-1-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman

vt: use newly defined CUR_* macros

2020-06-24T15:08:33+00:00

We defined macros for all the magic constants in the previous patch. So let us use the macro in the code now. No functional change intended.

vc: switch state to bool

2020-06-24T15:08:31+00:00

The code currently uses bitfields to store true-false values. Switch all of that to bools. Apart from the cleanup, it saves 20B of code as many shifts, ANDs, and ORs became simple movzb's.

vt: introduce enum vc_intensity for intensity

2020-06-24T15:08:31+00:00

Introduce names (en enum) for 0, 1, and 2 constants. We now have VCI_HALF_BRIGHT, VCI_NORMAL, and VCI_BOLD instead. Apart from the cleanup, 1) the enum allows for better type checking, and 2) this saves some code. No more fiddling with bits is needed in assembly now. (OTOH, the structure is larger.)
