v3: Rebased due to Makefile changes. If there are no objections,
I'll apply this next weekend.
v2: Rebased. Updated 07/25: removed confused comment and split
sse_op_table3 so that void pointers are avoided there too, adjusted
08/25 accordingly.
v1: I only sent the tree URL.
Blue Swirl (25):
x86: prepare op_helper.c for splitting
x86: avoid AREG0 for exceptions
x86: split off exception handlers
x86: avoid an extern declaration
x86: fix coding style in ops_sse.h
x86: split off FPU helpers
x86: improve SSE table type safety
x86: avoid AREG0 for FPU helpers
x86: fix coding style in helper_template.h
x86: split condition code and shift templates
x86: prepare eflags helpers for general use
x86: split off condition code helpers
x86: avoid AREG0 for condition code helpers
x86: split off integer helpers
x86: avoid AREG0 for integer helpers
x86: split off SVM helpers
x86: avoid AREG0 for SVM helpers
x86: split off SMM helpers
x86: avoid AREG0 for SMM helpers
x86: split off misc helpers

25 siblings, 0 replies; 33+ messages in thread
From: Blue Swirl @ 2012-06-09 16:18 UTC (permalink / raw)
To: qemu-devel
Add an explicit CPUX86State parameter instead of relying on AREG0.
Merge raise_exception_env() to raise_exception(), likewise with
raise_exception_err_env() and raise_exception_err().
Introduce cpu_svm_check_intercept_param() and cpu_vmexit()
as wrappers.

To: qemu-devel
SSE function tables could easily be corrupted because of use
of void pointers.
Introduce function pointer types and helper variables in order
to improve type safety.
Split sse_op_table3 according to types used.

From: Blue Swirl @ 2012-06-09 16:19 UTC (permalink / raw)
To: qemu-devel
Make FPU helpers take a parameter for CPUState instead
of relying on global env.
Introduce temporary wrappers for FPU load and store ops. Remove
wrappers for non-AREG0 code. Don't call unconverted helpers
directly.

Move condition code helpers to cc_helper.c.
Move the shared inline functions lshift(), cpu_load_eflags() and
cpu_cc_compute_all() to cpu.h.

From: Blue Swirl @ 2012-06-09 16:19 UTC (permalink / raw)
To: qemu-devel
Add an explicit CPUX86State parameter instead of relying on AREG0.
Rename remains of op_helper.c to seg_helper.c.

From: Blue Swirl @ 2012-06-09 16:19 UTC (permalink / raw)
To: qemu-devel
Add an explicit CPUX86State parameter instead of relying on AREG0.
Remove temporary wrappers and switch to AREG0 free mode.

Thanks for rebasing and pushing.
Unfortunately I'm seeing a regression booting openSUSE 12.1 64-bit GNOME
Live CD [1] with qemu-system-x86_64: It hangs after initializing the
mouse whereas on master it proceeds into the graphical installer.

The site does not respond. Could you try to bisect which patch causes
the problem?

After kernel has been loaded, the screen flashes black and there's a
screen with SUSE logo, then nothing happens. But this is also the case
with 1.1.0, master and after the series. Even with KVM, there's one
more screen flash and the screen resizes but nothing happens after
that.
I'm now trying Debian 6.0.4 live amd64.

I can now reproduce the problem with Debian, without the patch set
there's text about loading, but with the patch the screen remains
blank forever.
It looks like the problem is with the patch 'x86: avoid AREG0 for FPU
helpers'. However, the only FPU instructions executed by Linux are
fxsave and fildl. Even if I revert those areas (even all memory access
changes), the problem remains.
The patch looks pretty straightforward otherwise.
I also checked that I didn't accidentally change register order like
before. The changed helpers which return a value can be found with
this:
$ git diff HEAD~1 HEAD target-i386/helper.h
target-i386/ops_sse_header.h |grep '^+'|grep DEF_HELPER |grep -v
'void, env'
+DEF_HELPER_1(fsts_ST0, i32, env)

+DEF_HELPER_1(fist_ST0, s32, env)

+DEF_HELPER_1(fisttl_ST0, s32, env)
+DEF_HELPER_1(fisttll_ST0, s64, env)
+DEF_HELPER_1(fnstsw, i32, env)

I hit ESC to see the mentioned progress message. Will check later.
