Now I need some input on a good way to detect if a keyboard has that Fn key. Currently I'm using the quirk approach, possible would also be to use hid_locate() as Rui Paulo did in http://fnop.net/~rpaulo/priv/freebsd/macbook-aug-1.diff and defining a option named UKBD_HAS_FN or something would work too. So what's the way to go for? To all Macbook (Pro) users, if you can afford some spare time and test the patch, feedback welcome. :) Regards, Bernhard Schmidt --------------000208050209040703010703 Content-Type: text/plain; x-mac-type="0"; x-mac-creator="0"; name="macbookfnkey.diff" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="macbookfnkey.diff" diff -ur /usr/src.orig/sys/dev/usb/ukbd.c /usr/src/sys/dev/usb/ukbd.c --- /usr/src.orig/sys/dev/usb/ukbd.c 2008-04-26 18:40:35.000000000 +0200 +++ /usr/src/sys/dev/usb/ukbd.c 2008-04-26 18:50:23.000000000 +0200 @@ -110,6 +110,9 @@ typedef struct ukbd_softc { device_t sc_dev; /* base device */ + int sc_flags; +#define UKBD_FNKEY 0x01 +#define UKBD_HASFN 0x01 } ukbd_softc_t; #define UKBD_CHUNK 128 /* chunk size for read */ @@ -191,6 +194,11 @@ id = usbd_get_interface_descriptor(iface); + if (usbd_get_quirks(uaa->device)->uq_flags & UQ_APPLE_HAS_FN) { + device_printf(self, "Apple Macbook Fn key detected\n."); + sc->sc_flags |= UKBD_HASFN; + } + arg[0] = (void *)uaa; arg[1] = (void *)ukbd_intr; kbd = NULL; @@ -206,6 +214,8 @@ #endif if (bootverbose) (*sw->diag)(kbd, bootverbose); + if (sc->sc_flags & UKBD_HASFN) + kbd->kb_flags |= UKBD_HASFN; return 0; } @@ -364,6 +374,7 @@ int ks_mode; /* input mode (K_XLATE,K_RAW,K_CODE) */ int ks_flags; /* flags */ #define COMPOSE (1 << 0) +#define FNKEY (2 << 0) int ks_polling; int ks_state; /* shift/lock key state */ int ks_accents; /* accent key index (> 0) */ @@ -866,6 +877,7 @@ c = -1; } else { c = state->ks_input[state->ks_inputhead]; + DPRINTF(("ukbd_getc: read %04x\n", c)); --state->ks_inputs; state->ks_inputhead = (state->ks_inputhead + 1)%INPUTBUFSIZE; } @@ -1031,6 +1043,53 @@ return NOKEY; ++kbd->kb_count; + if (!(kbd->kb_flags & UKBD_HASFN)) + goto no_fn_key; + + /* fn key pressed */ + if (usbcode == UKBD_FNKEY) { + if (!(state->ks_flags & FNKEY)) { + state->ks_flags |= FNKEY; + DPRINTFN(1, ("ukbd_read_char: fn key pressed\n")); + } + --kbd->kb_count; + goto next_code; + } + + /* fn key released */ + else if (KEY_INDEX(usbcode) == UKBD_FNKEY) { + if (state->ks_flags & FNKEY) { + state->ks_flags &= ~FNKEY; + DPRINTFN(1, ("ukbd_read_char: fn key released\n")); + } + --kbd->kb_count; + goto next_code; + } + + /* translate scancodes while fn key is pressed */ + else if (state->ks_flags & FNKEY) { + DPRINTFN(2, ("ukbd_read_char: translate: %04x\n", usbcode)); + switch (KEY_INDEX(usbcode)) { + case 0x2a: /* delete */ + usbcode = 0x4c | (usbcode & KEY_RELEASE ?
