RE: Memory Allocation !!

[Sanjay Cartic <scartic@ixiacom.com>]

I dont use multiple BARs but I was able to get up to 256MB allocated
to a single BAR on an Intel motherboard after a BIOS update. Before 
that 16M was what it would allocate to one BAR!





Hi Experts,

I am working on a chipset which requires near about 32MByte of memory
allocation through one of the BAR's.
And on our system you can have multiple  of these chipset on the same
PCI bus.

Have anyone of you encountered problems with allocation of multiple
large memory maps on  a PCI system ?
Can OS handle such large allocations ?
If not, how do we solve this issue on a system level or OS level.
(We support a wide range of OS).
