I'm trying to get Shadow status working in the savage driver. I'd like to put the status page into locked shared memory and tell the Savage chips about its physical address. I used a drmAddMap call copied from the MGA driver that looked like it did what I wanted. But I had to find out that the handle returned by drmAddMap is a kernel virtual address, not a physical address. Later I saw that the status page seems to be unused in the MGA driver. The code to get the physical address from the kernel virtual address is #if-ed out, probably for portability reasons.
It looks like drmAddBufs with count one and size PAGE_SIZE would be a way to get what I want. Though it's probably not what this interface was meant for. Does anyone want to talk me out of it before I start coding? ;-) Thanks for any insight, Felix -- | Felix K�hling <[EMAIL PROTECTED]> http://fxk.de.vu | | PGP Fingerprint: 6A3C 9566 5B30 DDED 73C3 B152 151C 5CC1 D888 E595 | ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
