user land progress
- @16-02-2009, the stage3 armv4l has been started
- @18-02-2009, ready to boot a minimal stage1 with init=/bin/bash root=/dev/hda3
- @23-02-2009, stage3 has been finished, tested, well running and able to compile
- @23-02-2009, stage3 is OK, stage4 has been started wirh xorg-x11 in mind (QT embedded is under studying)
- @02-03-2009, stage4 has branched into microwindows stuff, nanoX has been compiled, tested, well running
- @03-03-2009, wonder about an other branch to "QT-extended" ...
kernel last report
- @ 03-2009, 2.6.29.colie
** lcd: working ** backlight : NOT working ** touchscreen : NOT working ** buttons: NOT working ** battery: NOT working (new battery device interface) ** sound: NOT working ** usb: NOT working ** RTC: working ** compactflash: not working ** pcmcia: sleeve 1xpcmcia is working with pATA-pcmcia-16bit/5V
- @ 03-2009, 2.6.19-hh
** lcd: working ** backlight : working ** touchscreen : working, but it seems there is no handler ** buttons: working ** battery: NOT working (new battery device interface) ** sound: NOT working ** usb: NOT working ** RTC: working ** compactflash: not working ** pcmcia: sleeve 1xpcmcia is working with pATA-pcmcia-16bit/5V
@ grem proof 03-03-2009
used as working branch
how to switch it on/off ? using the sysfs class
used: micro_ts + ts kernel module
SA1100_BITSY seems to be missing
config TOUCHSCREEN_BITSY 33 tristate "Compaq iPAQ H3600 (Bitsy) touchscreen" 34 depends on SA1100_BITSY 35 select SERIO 36 help 37 Say Y here if you have the h3600 (Bitsy) touchscreen. 38 39 If unsure, say N. 40 41 To compile this driver as a module, choose M here: the 42 module will be called h3600_ts_input.
just to have an idea of what was done http://www.handhelds.org/hypermail/kernel-discuss/attachment.html
new MACHINE_START definition for ipaq h3600 From: Alessandro GARDICH <gremlin_at_gremlin.it> Date: Mon, 14 Nov 2005 21:11:35 +0100 Nothing change, just to follow the new way for the definition. * text/x-patch attachment: handhelds-sa-26.patch
ipaq h3600 - patch for new egpio functions From: Alessandro GARDICH <gremlin_at_gremlin.it> Date: Sat, 19 Nov 2005 18:30:22 +0100 Nothing change, just to follow the new way *_egpio function. Remain out only micro that have to be full rewriten and uda1341 OSS driver, alsa one should work.
From: Alessandro GARDICH <gremlin_at_gremlin.it> Date: Fri, 06 Jan 2006 18:23:16 +0100 Hi to all, another patch for iPAQ h3600 epiphany patch : * arch/arm/common/ipaq/micro.c : - estetic code clean-up - support for keys device - backlight device definition - backlight are now restored after framebuffer blank/resume * arch/arm/common/ipaq/micro_key.c : - support for keys (5 application keys and 4 directions pad) * arch/arm/common/pxa_keys.c : - moved from arch/arm/mach-pxa/pxa_keys.c - small changes to be used also for h3600 device * arch/arm/mach-sa1100/h3600.c - add support for power and action keys - backlight device definition moved in micro.c * include/asm-arm/arch-pxa/pxa_keys.h - to not break existing pxa code it only include hardware/pxa_keys.h * include/asm-arm/arch-sa1100/h3600_gpio.h - add definition for GPIO number (not bit) for action button * include/asm-arm/arch-sa1100/h3600.h - add definition for GPIO number (not bit) for power button * include/asm-arm/arch-sa1100/irqs.h - macro to get IRQ for a giver GPIO * include/asm-arm/hardware/pxa_keys.h - moved from include/asm-arm/arch-pxa/pxa_keys.h There are still some issues with micro* modules after sustend/resume and when unloading. This is really the epyphany patch, the end of xmas vacation. From monday work and pool start again and so spare time will be just few hours for day. :) But i'll continue ... I'm also looking on ebay if I can find a cheap h37xx and h38xx to take care of such iPAQs also.
Re: [PATCH] RTC classdev: Add sysfs support for wakeup alarm (r/w) From: David Brownell <david-b_at_pacbell.net> Date: Mon, 18 Dec 2006 16:59:11 -0800 On Monday 18 December 2006 4:54 pm, David Brownell wrote: > > http://handhelds.org/cgi-bin/cvsweb.cgi/linux/kernel26/drivers/rtc/rtc-sa1100.c.diff?r1=1.5&r2=1.6&f=h > > That patch you applied looks right to me -- why don't you forward it > to Alessandro as a bugfix for 2.6.20-rc2, and save me the effort? Actually, correction: it'd be correct if you ripped out the buggy calls to manage the irq wake mechanism. A later message will show how those need to work. (The IRQ framework will give one helpful hint when it warns about mismatched enable/disable calls ...) - Dave
iPAQ h3600 - patch for 2.6.19 From: Alessandro GARDICH <gremlin_at_gremlin.it> Date: Sun, 10 Dec 2006 18:07:13 +0100 Hi all With this patch also h3600 will compile and run kernel 2.6.19 - irq calling loose registers parameter - platform device/driver in h3600_lcd - minor cleanup see u soon
Re: Funky breakage with w100fb imageblit patch * This message: [ Message body ] [ Respond ] [ More options ] * Related messages: [ Next message ] [ Previous message ] [ In reply to ] [ Next in thread ] From: Manuel Teira <manuel.teira_at_telefonica.net> Date: Sun, 10 Dec 2006 20:54:32 +0100 A fast note about performance: It seems that the performance problem is not the imageon itself. After one of my tests, I found in my dmesg lines like: <4>Alignment trap: font (1269) PC=0x4002f9f4 Instr=0xe592c000 Address=0x00012726 FSR 0x013 The problem is the font itself: as any character is 14 bytes (for the 7x14 font) not all the char pointers fall in a word boundary and so, we're forcing the cpu to correct the missalignment. I have a little libw100 test program, to fill the screen with a given text. This is what I got when I use a nonaligned char, like "1": root_at_c7x0:/media/card/libw100/bin$ ./font 0 1 "1" Written 3094 characters in 19 seconds. Rate: 162.422116 cps And using an aligned one, like "2": root_at_c7x0:/media/card/libw100/bin$ ./font 0 1 "2" Written 3094 characters in 0 seconds. Rate: 16563.169165 cps This is like the performance I got using the 8x16 font, so, the problem seems to be the misalignment of the font, and not the imageon itself. Regards.
