Subject: [PATCHv2 0/4] x86, entry: some cleanup and simplification...
Date: Sun, 18 Jan 2015 12:45:16 +0100 [thread overview]
Message-ID: <1421581520-2816-1-git-send-email-heukelum@fastmail.fm> (raw)
Hi Andy,
The last patchset did not compile on i386. Please ignore it. This one
should be better. Instead of removing KERNEL_STACK_OFFSET, it is now
used consistently on both i386 and x86_64.
Boot tested using qemu (using klibc for userspace)
- x86_64, 32-bit userspace, core2duo (sysenter32)
- x86_64, 32-bit userspace, phenom (syscall32)
- x86_64, 32-bit userspace, vdso=0 (int 0x80)
- x86_64, 64-bit userspace
- i386, pentium3 (sysenter)
- i386, athlon (syscall)
- i386, vdso=0 (int 0x80)
They were tested on top of 22f2aa4a0361707a5cfb1de9d45260b39965dead
(x86/entry-devel in your tree) and this kernel is now running on my
laptop.
Greetings,
Alexander
