Re: [9fans] kbdputc() in devcons.c in 9front?
You, 9front developpers, created kbdfs, and lost kbdputc() in port/devcdons.c. Most of pc/kbd.c stuffs are driven out to user space, kbdfs. In lab's or 9atom's distribution, I can have /rc/bin/Kanji, like: #!/bin/rc pipefile -r ktrans /dev/cons rio -i $home/lib/windows /dev/cons This assumes that the keyboard input from stdin, and produces kanji translated character to /dev/cons. This is solved by cinap to write a new program, pipekbd which works like pipefile for 9front's kbdfs. Now I can use Japanese on Plan9fron, too. Thanks cinap! Kenji
Re: [9fans] kbdputc() in devcons.c in 9front?
the problem is that rio reads /dev/kbd instead of /dev/cons which in addition provides key press and release events. so translating /dev/cons has no effect on rio. (rio reads and multiplexes /dev/kbd file) /dev/kbd is used by: games/doom, games/nes, games/snes, games/md and vnc. changing ktrans to translate /dev/kbd format instead of /dev/cons should not be hard. i can do that when i get back from my day job. kbdfs removes some code duplication like the latin1 composing. vncs in 9front just runs another instance of kbdfs to provide cons and kbd files instead of reimplementing the kernels console code. kbdfs also lets you interrupt programs on the plan9 console. -- cinap
Re: [9fans] kbdputc() in devcons.c in 9front?
i havnt tried this, but as a quick work arround for rio, you can make the /dev/kbd file unaccessible to rio with aux/stub so rio will revert to reading /dev/cons: aux/stub /dev/kbd pipefile -r ktrans /dev/cons rio -i $home/lib/windows /dev/cons -- cinap
Re: [9fans] kbdputc() in devcons.c in 9front?
As I said before, we have to save power as possible as we can I have a dual atom motherboard, a Supermicro X7SLA-H which is rather old now, but it still works fine. This is my cpu, auth, file, dns soa, and smtp/imap server. It has two mirrored enterprise grade 500Gb drives from different manufacturers (the idea is one will fail before the other). I plan to add an SSD to the mirror to hopefully speed venti. This draws about 23 watts. I run fossil+venti from the labs at present. I use an raspberry PI terminal (2 watts). The worsed offender is my DELL HD resolution display which draws 70 watts. currently the raspberry pi kernel does not send the CEC sequence to shut down the display when its idle (screen saver), but its on my list of things to fix. I use HDMI but believe if you attach the display via XVGA the syncs disappear on idle and shutdown the display correctly but I have not tried this. I also have a green router/wifi basestation/ADSL modem which draws 5 watts. -Steve

Re: [9fans] kbdputc() in devcons.c in 9front?
wheres the source code of the ktrans that you are
using?
i looked at /n/sources/extra/ktrans-2e.tgz but this
one would require the -t flag to work like you intended
in your mail:
if (argc1 strcmp(argv[1], -t)==0) {
tflag = 1;
in = 0;
out = 1;
} else {
if ((in = open(/dev/kbd, OREAD)) 0)
exits(open /dev/kbd read);
if ((out = open(/dev/kbd, OWRITE)) 0)
exits(open /dev/kbd/write);
if (rfork(RFPROC))
exits(0);
atnotify(noter, 1);
}
are you using a different ktrans than this? and if yes,
could you point me to the source?

Re: [9fans] kbdputc() in devcons.c in 9front?
kbdfs removes some code duplication like the latin1 composing. vncs in 9front just runs another instance of kbdfs to provide cons and kbd files instead of reimplementing the kernels console code. i found the major source of duplication was the n copies of (different!) scan code tables in the various /sys/src/9/*/kbd.c these differences appear to all be accidental. consolidating them into port/devpckb.c which provides both /dev/kbin and /dev/kbmap, and removing or reducing $arch/kbd.c to $arch/i8042.c got a lot of the cleanup done without breaking interfaces. it would be nice to get away from the annoying pc scan code interface, but the cost is going to be compatability, and that cost seems too much to me at this point. the only way to do something like this imo would be to agree and coordinate changes. /dev/kbd seems reasonable if you've got that kind of problem. but i don't see the benefit to using it where not formerly required, but i do see a compatibility downside. i also prefer having the keyboard in the kernel, since i do have kernels with no user space. norio(8) was written to deal with console interrupt for a particular project. think of it as rio with no graphics, and one pre-defined window. but i don't think it's a very good idea. there are better options. (like rio.) and yes, that's like, ya know, my opinion, man. so like, whatever. :-) - erik

Re: [9fans] kbdputc() in devcons.c in 9front?
rio multiplexes /dev/kbd, so it opens it and derives the windows kbd and cons files from it. it obviously has to read /dev/kbd to multiplex it. now, the incompatibility is that opening /dev/kbd disables /dev/cons input. the reason is that /dev/cons is buffered but pressing keys on the keyboard will result in characters being queued to /dev/cons. /dev/kbd reading programs should *not* require a dummy reader proc to flush duplicated console input in addition to reading /dev/kbd. you open /dev/kbd and the keyboard is yours. it is also harder to filter or translate multiple asynchronously read file stremas instead of just one. and filtering /dev/kbd is not much differnet from filtering /dev/cons. in addition, you have keyboard chords. -- cinap
Re: [9fans] kbdputc() in devcons.c in 9front?
wheres the source code of the ktrans that you are using? It's not the one you checked. I'll send it to you by private mail. If I could have a time I'll change it to be able to open everyone. It was worked using my business time at office. I'm now not a enpryee of that organization. Kenji

[9fans] kbdputc() in devcons.c in 9front?
I'm checking how I should build my Plan9 system in my home environment. As I said before, we have to save power as possible as we can (no nuclear power energy here). If I choose one file/auth/cpu server machine, Plan9front may be fastest. However, I have here one serious problem. Ktrans does not work on it. You, 9front developpers, created kbdfs, and lost kbdputc() in port/devcdons.c. Most of pc/kbd.c stuffs are driven out to user space, kbdfs. In lab's or 9atom's distribution, I can have /rc/bin/Kanji, like: #!/bin/rc pipefile -r ktrans /dev/cons rio -i $home/lib/windows /dev/cons This assumes that the keyboard input from stdin, and produces kanji translated character to /dev/cons. What is the merrit to create kbdfs? I cann't see it, but only demerit like above. Kenji
