[...] >=20 Can you please compile and run the following utility on sparc64, on any non-busy /dev/kbd*? : #include <sys/kbio.h> : #include <sys/ioctl.h> : #include <err.h> : #include <stdio.h> : #include <stdlib.h> :=20 : int : main(void) : { : int mode; :=20 : if (ioctl(0, KDGKBMODE, &mode) =3D=3D -1) : err(1, "ioctl(KDGKBMODE)"); : printf("current mode =3D %d\n", mode); :=20 : if (ioctl(0, KDSKBMODE, mode) =3D=3D -1) : err(1, "ioctl(KDSKBMODE)"); :=20 : if (ioctl(0, KDGKBMODE, &mode) =3D=3D -1) : err(1, "ioctl(KDGKBMODE)"); : printf("current mode =3D %d\n", mode); :=20 : exit (0); : } On my i386 notebook after "kldload kbdmux" and the following config as a result: lrwxr-xr-x 1 root wheel 6 Jan 1 1970 /dev/kbd0 -> atkbd0 lrwxr-xr-x 1 root wheel 7 Sep 20 00:43 /dev/kbd1 -> kbdmux0 : ./a < /dev/kbd1 : current mode =3D 1 : current mode =3D 1 If it works properly on sparc64, it should be identical. If you'll see a different value in the second "current mode", it'll indicate an endianness bug we're talking about.
