Why do you want to do that in a driver ? I'm assuming from the past questions from Dolphinics this is still about driver development. There is no guarantee that this stays they same and could change just after you have looked at it. I'm also very nervous about any driver that makes any assumptions based on the size of memory. > We have a device driver running on Linux that does the following: > > #define DX_TOTALRAM (((U64)num_physpages) << PAGE_SHIFT) > > Can you tell me if there is something similar to 'num_physpages' on > Solaris? PAGE_SHIFT is used to find out the page size. I should use > 'ptob(1)' to get the page size, shouldn't I? physmem might be the symbol you are looking for. That is ptob(9F) of course, running a ptob command inside the kernel would be tricky :-) But physmem already is the size in bytes. If you want it in pages use btop(9F). Also you probably should use the ddi_ptob(9F)/ddi_btop(9F) versions. -- Darren J Moffat _______________________________________________ opensolaris-code mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
