WebThis function verified that the memory area starting at address ‘addr’ and of size ‘size’ was accessible for the operation specified in type (read or write). To do this, verify_read had to look up the virtual memory area (vma) that contained the address addr. In the normal case (correctly working program), this test was successful. WebThis code is the general case. Access to set_fixmap is done via the kernel patching interface: patch_text(). Right now, the patch_text interface checks cache_ops_need_broadcast(), and conditionally runs under stop_machine(). We could make this unconditional, and we'll avoid any problem with TLB misses on another CPU.
