Hello Experts,
I have added new pass through device to the VirtualBox setup .
Registered all 6 BAR's with appropriate sizes, none exceeding 256M.
All BAR's were set to reflect hardware functionality (assigned 0),
eventually OS programmed base address regions with the sizes I have
registered them with.
Can you provide more details (how you map the regions initially and on
remap)? Hard to say what's happening otherwise.
My fundamental problem is, I have been able to access BAR0 and NOT
BAR5. I tried playing with BIOSmmio address setting in DevPciIch9,
that made difference in relocating BAR's but functionality remained
the same (Not able to access BAR5)
Interesting part is, PIIX3 chipset is fully functional ie., can access
BAR5 in PIIX3 but NOT in ICH9.
Could be that with PIIX3 there's no remap and with ICH9 there's a
remap... really difficult to say anything with the sparse information.

PS: There seems to be some problem with my email ID, so not sure
whether my last email came through. Sorry if you have already received
it.
Thanks.
