The way the Linux kernel manages the MMU on e500 it doesn't actually=20
ever modify MSR[IS] or MSR[DS]. They are always zero so I dont believe=20=
you are hitting this errata.
Are you running with math emulation turned on? Do you know what the=20
instruction is that causes the SIGILL?

Is anyone interested in going to the OLS this year? I've been working in
Ottawa for 4 years so if you are interested I can give anyone more
information about things to do in Ottawa.
Just heads up for those planning to go, the deadline for early bird
registration is May 1 I think. You save CAN $150 (350 as opposed to 500).

At Nanometrics, we have compiled Konqueror-embedded, kdenox, and

Total memory usage of the browser is around 20Megs.
I don't believe ppc8xx is not too much different from the PowerPC 405, but
I might be wrong.

2. can we just use hard coded offsets for start & end values. I really

* PCI IO_BASE
From: Marco Schramel @ 2005-04-27 14:59 UTC (permalink / raw)
To: PPC_LINUX
Hi,
actually my system (2.4.25 on MPC8270 with PCI) runs fine and it will be tested. Thanks to all.
But one thing isn't really clear. The IO_BASE and memory windows for pci.
This is original taken from arch/ppc/plattforms/ads8260.h
/* window for a PCI master to access MPC8266 memory */
#define PCI_SLV_MEM_LOCAL 0x00000000 /* Local base */
#define PCI_SLV_MEM_BUS 0x00000000 /* PCI base */
/* window for the processor to access PCI memory with prefetching */
#define PCI_MSTR_MEM_LOCAL 0x80000000 /* Local base */
#define PCI_MSTR_MEM_BUS 0x80000000 /* PCI base */
#define PCI_MSTR_MEM_SIZE 0x20000000 /* 512MB */
/* window for the processor to access PCI memory without prefetching */
#define PCI_MSTR_MEMIO_LOCAL 0xA0000000 /* Local base */
#define PCI_MSTR_MEMIO_BUS 0xA0000000 /* PCI base */
#define PCI_MSTR_MEMIO_SIZE 0x20000000 /* 512MB */
/* window for the processor to access PCI I/O */
#define PCI_MSTR_IO_LOCAL 0xF4000000 /* Local base */
#define PCI_MSTR_IO_BUS 0x00000000 /* PCI base */
#define PCI_MSTR_IO_SIZE 0x04000000 /* 64MB */
#define _IO_BASE PCI_MSTR_IO_LOCAL
#define _ISA_MEM_BASE PCI_MSTR_MEMIO_LOCAL
#define PCI_DRAM_OFFSET PCI_SLV_MEM_BUS
#endif /* CONFIG_PCI */
These memory windows are not really clear to me. Which documentation can expand my theoretical background? Any comments are welcome.
If CONFIG_PCI is defined the io accesses will depend on the _IO_BASE (at example for ide accesses, now i know ;-)).
Why it depends on it ?
If i will adapt another chip with the standard io-accesses of /asm/io.h, which things i ve to know (offsets, windowsizes,etc..)?
Thanks for your comments.
Marco

Found it.
Now it works. RCCR[EIE] must be set.
But is this mentioned anywhere in the USB chapter of the manual?
NO! That would be too easy.

Pantelis.
PS. Please, would someone from freescale include this fine
point in the manual?
Thank you.

* USB Host on 8271 (A cry for help)

Hi there
I'm trying to get USB host mode to work on 8271 and I'm
stumped.
The major problem is that automatic SOF generation as mentioned
in the manual appears to not work (or it's not clear how to
enable it).
I'm trying to port the 8xx based driver, which works
adequately after applying the microcode patch.
Sadly usb host mode on 82xx appears to suck even more.
If anyone has *any* code that works for host mode on 82xx please
contact me.
Regards
Pantelis

Thanks a lot for the link, looks like my interpretation of events was
correct.
As a side note, I'd be great if _User manual_ has all this
information (and I always rant about Moto/Freescale manuals on
#mklinux) :)

Why don't you do it the other way( use u-boot). I just replaced
a vxWorks rom with u-boot and now I can happily boot vxWorks or
Linux on an 8260 based board...
