and CPU runtime because it can't access the user area via /proc/<pid>/mem. This is because the uarea is not mapped into the process address space at USRSTACK on the alpha like it is on the x86. Since I'm haven't been able to wrap my brain around the VM system enough to be able to figure out how to achieve this mapping, and since it's questionable that such an architectural change is correct, I implemented a workaround to allow ps(1) to read the uarea from /dev/kmem using kvm_read() instead of from the process address space via kvm_uread(). The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact the x86. (Note that top(1) probably uses this same gimmick since it works on FreeBSD/alpha.) Reviewed by: dfr |
