Hi,
The effort to add support for 64bit pci bars to qemu seems to have stalled somehow. Lets resume it ;)
Here is a patch collection, largely rewritten from scratch, which improves seabios 64bit support. One big patch (#3) adds 64bit math everythere. The other big patch (#5) adds support for ressource allocation above 4G. The remaining patches carry bugfixes and little bits such as support for printing 64bit hex numbers.
cheers, Gerd
ping?
I haven't really had a chance to review it. Initial thoughts were - on patch 1, I'm not sure how that will impact stack usage which is quite tight when running in 16bit mode; patch 5 - seems incomplete if it doesn't handle bridges properly. I didn't fully understand patch 5, but that's likely just due to lack of time to look at it.
BTW, what's the use case for 64bit PCI today?
