Researching for a new PDA environment

I'm still researching for a new PDA environment:
now I evaluate iplinux distribution/build system (based on debian) and EFL (enlightenment foundation libraries) . I hope 32mb is enough to run Xfbdev* with a light WM like DWM and some EFL environment. Some EFL-based apps were developed by openinkpot project, such as:
  • mpd-frontend (madaudio)
  • pdf-viewer
  • image-viewer (madeye)
And also there's efl-based browser (google for webkit-efl) developed by SHR project.

* or even xorg-server + xf86-video-fbdev, I heard that there's no difference between xorg-server and Xfbdev in recent releases, not sure if Xfbdev become too fat, or xorg-server become lighter)

Access point with Raspberry Pi and rtl8192cu dongle

On Thursday ethernet ports (WAN and LAN1-4) in my Asus WL500GPv1 router have completely died, so I needed a replacement. Hopefully, recently I've got Raspberry Pi, so I decided to use it as a router. I've got TP-LINK TL-WN821NC USB stick from local store which is based on RTL8192CU chipset. Unfortunately, its driver doesn't work with vanilla hostapd, but requires patched ancient version of hostapd from Realtek . I'm using Archlinux on my rpi and I've found manual how to setup AP using this USB stick  here , but I don't want to overwrite binaries from repository packages, since it's not a sane way, and it can (and will) be broken by hostapd update. So I prepared a package, here's source package (just unpack it and build with makepkg directly on rpi), and here's binary package for armv6h (you can install it with pacman -U). I can't put PKGBUILD in AUR, since there's no stable hosting for Realtek's hostapd. If anyone is willing to host

Wayland and software rendering

Image
Recently I spent few evenings for hacking wayland . I like idea of wayland - rendering is done completely on client (in whatever way), compositor (server part) is responsible in rendering buffers from clients on the screen. Issue for me was rendering part of weston (reference compositor for wayland) - it uses GLES for compositing, but I want to try wayland and weston on devices without hw acceleration (pure software rendering), and running software GL on PXA270@312MHz does not sound like a good idea, does it? :) So I asked on #wayland@irc.freenode.org if it possible to implement software renderer, Kristian Høgsberg (khr) responded that in master branch of weston repo there's a nice abstraction of renderer, so it's possible to implement pixman renderer. So I did :) weston with x11-backend and pixman renderer khr and pq from #wayland were very helpful, and described place of renderer in wayland architecture, here're some points renderer just performs rendering of

qemu with Z2 support

I spent some days getting qemu to emulate some Z2 hardware, and got some results :) Almost all hw is emulated, it lacks only voltage regulator and WiFi, but it's not easy to implement Marvell's WiFi chip, because there's no datasheet, and anyway it makes no sense. Also screen rotation is not supported (yet). Stock bootloader - blob - (with slight modification) and stock kernel works. Blob puts Z2 into deepsleep on reset, so I hacked it not to do this. How to compile qemu: git clone git://github.com/anarsoul/qemu-z2.git cd qemu-z2 ./configure --audio-drv-list=alsa --target-list=arm-softmmu make -j4 arm-softmmu/qemu-system-arm binary is what you need. So, how to hack blob: put your blob image (first 64kb of NOR) somewhere convert it to hex representation with xxd: xxd mtdblock1.bin >mtdblock1.hex apply patch onto mtdblock1.hex convert hex back to bin: mv mtdblock1.bin mtdblock1.bin.bak; xxd -r mtdblock1.hex >mtdblock1.bin I don't pu
