Re: [Qemu-devel] How to measure guest memory access (qemu_ld/qemu_st) time?

[YeongKyoon Lee <yeongkyoon.lee@samsung.com>]

Hi,

I proposed QEMU ld/st optimizations two times, late last year and early this year, however, there was no replies and even more 0/3 patch mail in this year has been missed so I cannot find the mail in QEMU mail archives. :(
The link of 0/3 (http://www.mail-archive.com/qemu-devel@nongnu.org/msg91294.html) is old one in last year.

Anyway, the other links of patches (1/3~3/3) are as follows.
http://lists.nongnu.org/archive/html/qemu-devel/2012-01/msg00026.html
http://lists.nongnu.org/archive/html/qemu-devel/2012-01/msg00027.html
http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg00028.html

Because there was no replies from qemu-devel, I have applied the patches only to Tizen emulator, where Tizen is a new mobile platform of Linux foundation.
At this time, QEMU mainline has been changed since the patches, so I'll propose them again after some modification for latest sources.

Thanks.

  I only see PATCH 0/3, any idea on where the others?
