Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

Merge patch series "Resolve issues with booting distros on x86"

2024-04-11T02:01:42Z

Simon Glass says: This little series reprises the EFI-video fix, fixes a USB problem and enables a boot script for coreboot. It also moves to truetype fonts for coreboot and qemu-x86, since the menus look much better and there are no strong size constraints. With these changes it is possible to boot a Linux distro automatically with U-Boot on x86, including when U-Boot is the second-stage bootloader.

video: Correct setting of cursor position

2024-04-11T02:01:33Z

The ANSI codes are not correctly handled at present, in that the requested X position is added to the current one. Correct this and also call vidconsole_entry_start() to start a new text line. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

video: console: Parse UTF-8 character sequences

2024-03-21T05:56:13Z

efi_console / UEFI applications (grub2, sd-boot, ...) pass UTF-8 character sequences to vidconsole which results in wrong glyphs for code points outside of ASCII. The truetype console expects Unicode code points and bitmap font based consoles expect code page 437 code points. To support both convert UTF-8 to UTF-32 and pass Unicode code points in vidconsole_ops.putc_xy(). These can be used directly in console_truetype and after conversion to code page 437 in console_{normal,rotate}. This fixes rendering of international, symbol and box drawing characters used by UEFI applications. Signed-off-by: Janne Grunau

video: Support showing a cursor

2023-10-11T19:43:55Z

Add rudimentary support for displaying a cursor on a vidconsole. This helps the user to see where text is being entered. The implementation so far is very simple: the cursor is just a vertical bar of fixed width and cannot be erased. To erase the cursor, the text must be redrawn over it. This is good enough for expo but will need enhancement to be useful for the command-line console. For example, it could save and restore the area behind the cursor. For now, enable this only for expo, to reduce code size. Signed-off-by: Simon Glass

video: Export vidconsole_entry_start()

2023-10-11T19:43:55Z

At present this is called only when a newline is detected, since this indicates the start of a line of text being entered. Export this function so it can be used by expo, which may start a new text line itself, without first writing out a newline. Signed-off-by: Simon Glass

video: Allow saving and restoring text-entry state

2023-10-11T19:43:55Z

Text entry operates within a context which includes quite a bit of information. For example, with Truetype fonts, each character in the text string has a position stored, so that it is possible to backspace to that character. This information is built up as strings are drawn on the display. For the command line, there is just a single context. It is created when command-line entry starts and it is destroyed (or at least not needed anymore) when the user presses to enter the command. By contrast, expo needs to be able to switch in and out of a text-entry context, since it is also displaying other objects in the scene. Add a way to save and restore the entry context for a vidconsole. This is only needed for the truetype vidconsole, so add a method for that, storing the information in an abuf struct.

video: Allow obtaining the nominal size of a string size

2023-10-11T19:43:55Z

At present there is a method for measuring text, but if the actual text string is not known, it cannot be used. For text editor we want to set the size of the entry box to cover the expected text size. Add the concept of a 'norminal' size with a method to calculate that for the vidconsole. If the method is not implemented, fall back to using the font size, which is sufficient for fixed-width fonts. Signed-off-by: Simon Glass
