Re: Proposed new kernel noncaching memory allocator for the 405gp

Dan,

No, the transmit descriptors in the USB  code are much less than a page.  Look
at ohci-usb.c
Why do a kmalloc?  And what about SCSI and it linked list?  These need bytes and
not whole pages.



Any I'll do it and submitt it .

Yes, but these allocate on a page boundry and I was thinking of something a
little more granular.

You can only control cache behavior on page boundaries at best, and
from the few drivers I have looked at, this is exactly what they
expect.

Any objections?

I have been listing them in previous messages.
