Re: demuxing irqs
How do the virq numbers get assigned?
What do I pass into request_irq when I use one of these pins?
The gpio device...
gpio_wkup: [EMAIL PROTECTED] {
compatible =
fsl,mpc5200b-gpio-wkup,fsl,mpc5200-gpio-wkup;
reg = 0xc00 0x40;
interrupts = 0x1 0x8 0x0 0x0 0x3 0x0;
interrupt-parent = mpc5200_pic;
gpio-controller;
#gpio-cells = 4;
};
use of a gpio from the device...
[EMAIL PROTECTED] {
compatible = digispeaker,gpio-ir;
gpios = gpio_wkup 0 0 1 0;
};
0 - gpio number in the device
0 - enable open drain
1 - class of interrupt, normal or wakeup
0 - type of interrupt, rising, falling, both, pulse

Re: Device treee syntax for expanding mpc5200 gpios

Right now we have: gpios = gpio_wkup 0 0; first cell is index into the bank, and second is unused. What do we need to fully describe a mpc5200 gpio? 1) open drain: 1 enable 2) interrupt: 0 no int, 1 simple, 2 wakeup, 3 both 3) interrupt type: 0 any transition, 1 rising, 2 falling, 3 pulse Maybe I'm misunderstanding the situation, but 2 and maybe 3 look more like configuration than something inherent to the hardware setup. Couldn't different drivers potentially choose different interrupt modes depending on their needs?

Re: [PATCH]: [MPC5200] Add ATA DMA support

I can pick it up for -next if everything else looks good. Here are the new patches; tested against 2.6.27-rc3. Hi Tim, I finally got a chance to try out your patches on my lite5200 board. Unfortunately, I wasn't able to get it to work easily. I'm very early in the debugging this issue, but I thought I'd send you my results in case you've seen it before. I've tried this with both an STEC 1GB CF and a Transcend Ultra industrial 1GB CF card. When the patch is enabled, Linux boots to the point of probing the ATA bus. The first attempt to probe uses UDMA/33 which ends in a timeout. Second attempt limits it to UDMA/25 which also times out. Third attempt falls back to PIO4 mode which then succeeds and the boot process continues. I haven't dug into the details of MPC5200 UDMA support yet, but I'd like to know if you have any ideas.

Re: demuxing irqs
YDL has pretty much followed the Red Hat distribution so focusing on learning how that works -- the RH manual can be directly downloaded from Red Hat -- should be the only thing one needs besides typical training available regarding good best practice strategies for nearly any Linux/Unix family of systems in applying System Administration strategies. Developing programming skills in the various computer languages are standard academic skills one can develop independently or via college. Of course after all that there remains the necessity of learning and applying what YDL is really great for -- mastery of the Cell via advanced mathematics. Now that is something which only YDL can allow you do exclusively and well. On Wed, Jul 16, 2008 at 5:40 PM, Posey, Jake E [EMAIL PROTECTED] wrote: Are there any training courses available for YDL?

I recall a discussion regarding gfortran sometime ago. I'm sure it
can be installed by using yum. The simplest way is probably:
#yum install gfortran*
You can make sure it's available by:
#yum info gfortran* or
#yum search gfortran*
The current package containing gfortran in YDL6 is
gcc-gfortran-4.1.1-52.ydl.1
I never attempted to compile gfortran from the sources.
However I did compile g95 (whicx1 0xe 0x0;
cell 1 = class critical, normal, sdma
cell 2 = number
cell 3 = level
Cell 3 is probably not needed in the existing definitions.
GPIO wake up interrupts come in on two different hardware interrupts
depending if they are normal or wake up.
gpio_wkup: [EMAIL PROTECTED] {
compatible =
fsl,mpc5200b-gpio-wkup,fsl,mpc5200-gpio-wkup;
reg = 0xc00 0x40;
interrupts = 0x1 0x8 0x0 0x0 0x3 0x0;
interrupt-parent = mpc5200_pic;
gpio-controller;
#gpio-cells = 4;
};
There's no existing API in the GPIO system to describe this case. You
have to decide if you want an interrupt to be able to wake the CPU up
from sleep mode. If you want the interrupt to do this, it will trigger
int 3 if the CPU is asleep, otherwise it triggers int 8. Should these
pins have two virqs? or should these two vectors be hidden from the
user of the interrupt?
