The hypercalls implementation for Linux and FreeBSD have two key headers, hypercall.h and hypervisor.h. I'm curious why the implementations for x86 and ARM* are so distinct.
I found it fairly straightforward to implement ARM* versions of the x86 _hypercall#() macros. Once that is done, most of the wrappers in the x86 hypercall.h can be moved to a shared hypervisor.h header. Why does Xen/ARM on Linux still have hypercall.S when merging the headers should reduce maintainance? Was GCC extended inline assembly language for ARM* thought too awful? I'm also curious why these headers are part of the Linux kernel, instead of being maintained by the Xen Project? -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | [email protected] PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
