https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246121 --- Comment #2 from Koine Yuusuke <koinec@yahoo.co.jp> --- Thank you for you interest in the patch. Unfortunately, I understand that the your suggestions are difficult for the following reasons. The virtual PS2 keyboard driver of the bhyve has a table for converting ASC= II code for keys that can be expressed in ASCII characters and Xorg keysym code for keys that cannot be expressed in ASCII characters (example Enter or Esc= ape key,etc) to ScanCode Set2 of the PS2 keyboard. This patch updates this conversion table based on the layout setting file. The /usr/share/vt/keymaps/* file contain the correspondence of ASCII charac= ters or key names (key names is unique to vt/syscons, not Xorg keysym) correspon= ding to the scancode (for vt/syscons) converted from ScanCode Set2 of the PS2 keyboard device. In addition, I confirmed that the conversion algorithm from ScanCode Set2 of the PS2 keyboard to scancode (for vt/syscons) is implemented in /usr/src/sys/dev/atkbdc/atkbd.c, so I think that it is not impossible to use the /usr/share/vt/keymaps/* file as the basis for the keys that can be represented by ASCII characters. (Since it has not been examined in detail, I don't understand whether ScanC= ode Set2 of the PS2 keyboard can actually be converted from scancode (for vt/syscons) to the reverse.) On the other hand, a key that cannot be represented by ASCII characters can= not be supported because the value of Xorg keysym value doesn't exist in /usr/share/vt/keymaps/* file. (For reference, the value of Xorg keysym value is in the /usr/local/include/X11/keysymdef.h) Therefore, even if the key layout conversion information that can be expres= sed in ASCII characters is acquired from /usr/share/vt/keymaps/* file, the key = that cannot be expressed in ASCII characters cannot be acquired from /usr/share/vt/keymaps/* file, and thus I think that a layout configuration = file for each language is required. If you have a good idea to use /usr/share/vt/keymaps/* file, please let me know. (I also don't want to have a layout configuration file for bhyve apart from /usr/share/vt/keymaps/* file. But I did this because I couldn't think of any other simple way...) - Koine Yuusuke (koinec) --=20 You are receiving this mail because: You are the assignee for the bug.=
