Just want to confirm winfast 6300 with flash rom. It behaves as the same as pcm-5823. Looks like copy pirq table only works with DOC. LinuxBIOS with flash rom doesn't need copy pirq table and probably won't work with CONFIG_COMPRESS=1.
the problem is confirmed then.
- Not all mainboard ports are mapping f0000 as RAM.
- It will not be possible to get rid of the memory hole (a0000-fffff) for all ports; some piece of this hole will always be required for some mainboards, at least that is what we have seen so far.
- You can not combine COMPRESS linuxbios with certain mainboards that use FLASH as the IRQ table will not get copied correctly
Conclusions: We will always need the option to turn COMPRESS off, at least until we verify that all our supported platforms can turn F0000 into RAM. But, again, I don't think this is going to be impossible, just a lot of work ;-)
Here are the combinations as I see them:
F0000 is FLASH F0000 is RAM can you COMPRESS? NO YES
Can you NOT COMPRESS? YES YES
Do you have to copy PIRQ? NO YES
did I miss anything?
