Re: [LinuxBIOS] util/getpir & util/mptable [Was "A boot problem...."]

Please note that some people consider running either util/getpir or util/mptable to be a waste of time. (I agree; Maybe these utilities could be fixed so they would be more useful on LinuxBIOS v2.)

Sorry, I worded the above paragraph far too strongly. I meant to say that booting a COTS BIOS & Linux and running util/getpir and util/mptable can be very useful in LinuxBIOS v2, but hand editing the results may be required. It would be nice, if util/getpir and util/mptable could be modified so hand editing the resultant irq_table.c and mptable.c would not be needed. This may not be very useful for experienced LinuxBIOS developers, but can save a lot of porting time for people who don't have as much LinuxBIOS or other BIOS experience.

ah! tell me how it needs to change. I just used getpir recently and did no hand editing. ron
If there are several peer root bus, the irq_table.c must be modified maually. Please refer to src/mainboard/tyan/s2895/irq_table.c YH On 7/28/05, Ronald G. Minnich <rminnich@lanl.gov> wrote:

Also, on AMD K8 CPUs it needs to be modified due to the difference in breadth-first vs depth-first bus enumeration, resulting in different bus numbers. Stefan

ah, somebody fix it please :-) ron
No, the irq table can be produced dynmaically as mptable.c the developer must change irqtable.c mptable.c manually to make it dynamically. YH On 7/29/05, Ronald G. Minnich <rminnich@lanl.gov> wrote:
