Hello,
I am beginning to doubt the credibility of 'getpir'.
I don't think it is a getpir issue. The issue is that, increasingly, the PIR tables in the BIOS are completely wrong. I see this more and more all the time, but it was a problem as long as 8 years ago.
It's a hard problem to resolve.
And, of course, the MP and ACPI tables have similar errors. I love PCs

Hello Ron,
I am so overjoyed by my experiment after the initial letter, that I must point this out to the list. Since two weeks now there has been a message that Linux could not find any routed irq-signal for the usb_uhci part with every Coreboot image that I so far have checked for my msi/ms6147. Based on the remark I made in the letter, I now corrected by hand the relevant entry in irq_tables.c to read
{0x00,(0x07<<3)|0x2, {{0x60, 0xdeb8}, {0x61, 0xdeb8}, {0x62, 0xdeb8}, {0x63, 0xdeb8}}, 0x0, 0x0}, /* USB-UHCI */
Here, Getpir had all '0x00' instead of every desired linkage '0x6#'.
Building and testing the new Coreboot is an almost complete success: the usb host controller is now getting an irq assigned and I can attach and mount a flash memory to the usb port!
The only shortcoming is that my specifications in i82371eb/Config.lb as to io and irq for this device 07:2 are completely ignored. Could some kind soul tell me how and where I can achieve such assignments at my will, and not having to trust some defaults that Coreboot somehow and somewhere pulls out of the hat.
Being pleased with todays progress with USB, I send my regards
I don't think coreboot pulls it out of a hat. I could have something to do with your southbridge code. Which southbridge do you have?
