The qemuppc is fine w/ powerpc or ppc603e. The mpc8315 is also fine w/ the 603e, but if someone wanted a ppce300c1 or c3 we could add it as necessary. (c1/c3 are basically 603e cores..) 23965 2 sgw 2012-08-13 15:24:41 +0000 If there is any additional issues, please re-open this 35661 3 raj.khem 2013-08-14 21:55:41 +0000 we use mac99 emulation for qemuppc, mac99 is essentially a G4 platform which means the 603e tunes are not exactly right for it. big difference I see is FPU is 64bit on ppc74xx whereas 603e has 32bit and additionally it has Altivec. I am reopening this bug to track activities if we have to add a new tune to match mac99 platform. 35670 4 raj.khem 2013-08-15 14:01:03 +0000 I have sent out a patch to add new appropriate tune files. it also needs a altivec to be enabled in kernel which I have already asked Bruce to add. once these two changes are in I will send out another patch to switch the default tune for qemuppc. 43125 5 raj.khem 2014-05-05 20:16:47 +0000 This has been fixed long ago by commit 9b5572b8014f23747f18a7e0ca30c7094c524920 Author: Khem Raj <raj.khem@gmail.com> Date: Thu Aug 15 10:35:27 2013 -0700 qemuppc: Change default tune to 74xx We use mac99 as platform for qemuppc lets choose a tuning thats appropriate for it Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> commit 52ea026df141ea23bbab38ad3a9733c15097eaa4 Author: Liming Wang <liming.wang@windriver.com> Date: Wed Jan 4 18:29:17 2012 +0800 qemuppc: replace emulation of qemuppc from prep to mac99 With this new emulation, existing qemuppc functionality is maintained and other functionality such as framebuffer + sato and NFS boot are added.
