m0ronic coder in LOL way: NetSurf / FrameBuffer

#netsurfがframbuffer portで盛り上がっていたので，モニョる． :DDD

 02/26 21:01:19 hiyuh
    what does NETSURF_FB_FRONTEND=able mean?
 02/26 21:01:50 hiyuh
    runtime linux/sdl detection?
 02/26 21:02:29 tlsa
    to pick whether to build nsfb for the linux, able or other framebuffer
 02/26 21:02:54 kyllikki
    the list is now able, sdl, linux and vnc
 02/26 21:03:16 kyllikki
    sdl, linux and vnc are mostly what you will be interested in

 02/26 21:24:47 hiyuh
    nsfb-{sdl,linux} doesn't work here. :(
 02/26 21:26:09 rjek
    You won't get much help without details :)

 02/26 21:27:11 hiyuh
    color is fscked up completely. :)
 02/26 21:27:22 rjek
    Oh, an endianess problem.
 02/26 21:27:30 rjek
    TTOTD: Don't use big-endian machines.
 02/26 21:27:33 rjek
    :)
 02/26 21:28:09 hiyuh
    keyboard/mouse doesn't work too, so I did force powerdown this
    powerbook. :DDD
 02/26 21:29:22 hiyuh
    tested only x86 boxes?
 02/26 21:29:27 rjek
    And ARM.
 02/26 21:29:33 rjek
    Extensively on ARM, in fact.
 02/26 21:29:39 hiyuh
    ah, k
 02/26 21:31:10 jmb
    awesome
 02/26 21:31:17 jmb
    kyllikki: that rocks
 02/26 21:41:02 jmb
    hiyuh: I assume keyboard/mouse work correctly under sdl?
 02/26 21:43:45 jmb
    as for endianness, it's likely in the plotters
 02/26 21:45:18 hiyuh
    jmb: sadly, nope. sdl's one said "Unable to init SDL: Unable to open
    mouse" then segv immediately (was tested on X/fbconsole).
 02/26 21:45:29 jmb
    hiyuh: oddness
 02/26 21:46:59 jmb
    hiyuh: I assume other SDL apps work?
 02/26 21:47:16 hiyuh
    jmb: let me check
 02/26 21:47:51 jmb
    hiyuh: because the SDL_Init() call we have is entirely standard :)
 02/26 21:51:09 hiyuh
    jmb: it works on X, but it doesn't work on fb. maybe, causes of
    "sdl's ones didn't work on X/fbconsole" are different.
 02/26 21:52:13 jmb
    hiyuh: right
 02/26 21:57:48 hiyuh
    jmb: I guess X blocks mouse device access from SDL when I was on
    fbconsole, I'll check w/o running X (no VT switch).
 02/26 21:57:50 jmb
    there. updated the application
 02/26 21:58:02 jmb
    hiyuh: wouldn't surprise me
 02/26 21:58:09 hiyuh
    yup, bbl

 02/27 00:17:11 hiyuh
    jmb: cause of SDL_init error comes from my udev rules were
    fscked up, sorry. even though, sdl's one still rocks. :)

 02/27 00:18:34 Kinnison
    hiyuh: are colours in web pages wrong too?
 02/27 00:18:40 Kinnison
    Or just the furniture?
 02/27 00:21:05 hiyuh
    nope, it can not show any page ATM.
 02/27 00:21:51 Kinnison
    Odd
 02/27 00:21:56 Kinnison
    why not?
 02/27 00:23:24 tlsa
    Kinnison: web page colours were wrong in is photo:

 02/27 00:27:06 Kinnison
    hmm
 02/27 00:27:39 Kinnison
    presumably this is kyllikki needing to support endianness stuff in
    his plotters?
 02/27 00:28:54 hiyuh
    fb_plotters_ablend()?
 02/27 00:30:37 Kinnison
    that's the alphablend isn't it?
 02/27 00:31:16 hiyuh
    I guess. it calculates r/g/b.
 02/27 00:50:09 kyllikki
    hi
 02/27 00:50:14 tlsa
    re k
 02/27 00:50:59 kyllikki
    right for big endien the least invasive way is to have different
    plotter c files built
 02/27 00:51:44 kyllikki
    e.g. fb_32bpp_plotters_be.c
 02/27 00:52:14 kyllikki
    because although the machines words are BE it appears the framebuffer
    display is LE
 02/27 00:52:39 kyllikki
    I suppose I could make it generic but...
 02/27 00:52:44 rjek
    How much of the code is actually different?
 02/27 00:52:47 rjek
    Might #ifdefing be better?
 02/27 00:53:08 kyllikki
    rjek: I really didnt want a load more #ifdeffery
 02/27 00:53:20 rjek
    Well, if large bits of the function will be different, I agree.
 02/27 00:53:30 kyllikki
    I am thinking of ways to remove the existing ifdefery
 02/27 00:53:52 kyllikki
    rjek: its every time an output colour is computed
 02/27 00:54:04 kyllikki
    so its not everso often
 02/27 00:57:04 kyllikki
    no, i see it
 02/27 00:57:08 kyllikki
    I can generalise it
 02/27 00:57:24 kyllikki
    in fact i ought to
 02/27 01:02:11 tlsa
    is it easy to add the rest of those pointers?
 02/27 01:06:42 kyllikki
    what #define can i use to determine endiness at compile time?
 02/27 01:09:55 hiyuh
    ? http://dev.gentoo.gr.jp/~hiyuh/misc/netsurf-gifread-try2fixonBE.diff
 02/27 01:11:02 kyllikki
    cool
 02/27 01:14:53 kyllikki
    try that?
 02/27 01:15:04 kyllikki
    I *think* my shifts are right
 02/27 01:15:50 kyllikki
    you get to test if #if __BYTE_ORDER == __BIG_ENDIAN is right
 02/27 01:16:45 hiyuh
    ACK
 02/27 01:19:38 *
    kyllikki waits paitently

 02/27 01:29:08 hiyuh
    lol

 02/27 01:29:46 hiyuh
    mouse/keyboard works. :)
 02/27 01:29:49 kyllikki
    hmm thats 32bpp?
 02/27 01:30:12 hiyuh
    dunno, just run nsfb on X.
 02/27 01:30:23 kyllikki
    well 32bpp is the default
 02/27 01:32:49 hiyuh
    let me try -linux.

 02/27 03:39:52 hiyuh
    on 32bpp nvidiafb, -linux shows red screen, keyboard/mouse doesn't
    work and cpu usage goes 100%  then I did force poweroff.
 02/27 03:40:01 hiyuh
    FYI, generic ppc machine uses offb which is 8bpp by default.
 02/27 03:40:05 hiyuh
    kyllikki: ^^
 02/27 03:40:39 kyllikki
    right, the 8bpp plotters may indeed be funted
 02/27 03:41:07 kyllikki
    hiyuh: I will take a look, maybe later maybe morrow
 02/27 03:41:15 kyllikki
    tired atm
 02/27 03:41:20 hiyuh
    k, thx
