Hi, I'm using this as a substitute for getting a virtual address for a specific
physical address on Solaris for my driver. If you see any issues in this
approach please let me know.
page_t p;
struct buf b;
memset(&p, 0, sizeof(p));
memset(&b, 0, sizeof(b));
p.p_pagenum = <your_page_frame_number>;
b.b_flags = B_PAGEIO;
b.b_pages = &p;
b.b_bcount = PAGE_SIZE;
bp_mapin(&b, 0);
if (bp->b_un.b_addr != NULL) {
/* Success */
}
if (hat_getpfnum(kas.a_hat, b.b_un.b_addr) == <your_page_rame_number>)
/* Success */
This seems to be working for me.
Regards,
Bhaskar.
