[Qemu-devel] Problems with Modifying "TranslationBlock"
Hi, everybody,
I have encountered an odd problem. I want to mark the "TranslationBlock" when
the code running on guest-os is a 'call' one or a 'ret' one. So I add some
member variables in "TranslationBlock" of "exec-all.h". Just like the
following:
typedef struct TranslationBlock {
target_ulong pc; /* simulated PC corresponding to this block (EIP + CS
base) */
..
struct TranslationBlock *jmp_first;
int is_call;// I add this if the translation block is a
'call' block
int is_ret; // I add this if the translation block is a 'ret'
block
}
Moreover, I add some codes in "Translation.c" to mark the current block 'call'
or 'ret'.
Although the code I add seems work well, the result is not correct. Moreover,
if I add the member variables before 'pc' in TranslationBlock, qemu does not
even work.
So can anyone help me? Thanks a lot in advance.
Kevin

[Qemu-devel] [PATCH] Patches from PyQemu project
Please see previous message for general PyQemu project description. Here are
the patches developed during the project:
1-qemu-override-mtype.patch
Add -mtype command line option to let override ARM MTYPE passed to the
kernel (useful for initial testing, prototyping, and debugging of new
machine).
2-qemu-mplugin.patch
Add -mplugin switch to allow loading of shared library and registering a
machine declared in it.
3-qemu-build-so.patch
Build QEMU as a shared library.
4-qemu-no-statics.patch
Remove static declaration from some QEMU symbols, so they were exported from
shared library.
5-qemu-gccxml-friendly.patch
This is auxiliary patch to make QEMY header C++ friendly, which is required
by gccxml, which in turn is required by ctypes utility h2xml to
automatically generate Python interface files from C headers.
6-qemu-extra-sdstate-accessors.patch
Few extra accessors for SDState structure (as was required to develop
emulation of ASIC3 SD controller). Alternative approach would be to make the
structure itself public.
Best regards,
Maria Zabolotnaya.

[Qemu-devel] [ANN] PyQemu 1.0 (and machine plugin patches)
Hello, My name is Maria Zabolotnaya, I am a Google Summer of Code student from Handhelds.org organization. This summer I worked on a project to create new ARM machine emulations using the Python programming language. I am glad to announce that the work is complete and results are available in the form of Python bindings for QEMU (PyQemu) and set of auxiliary patches to QEMU source code. The release 1.0 is available at this time at http://handhelds.org/~pfalcon/gsoc/ . It includes: 1. Python bindings for QEMU developed using ctypes Python module (native Python FFI (Foreign Function Interface), no C glue code is required; part of standard library since Python 2.5, available as add-on module for earlier versions). 2. Support for building QEMU as a shared library as required by ctypes to use it. 3. Patches to export more symbols and accessors from QEMU shared library. 4. Patch to allow to override ARM machine type from command line. 5. Patch to allow to load machine definitions from external shared libraries (plugins). 6. Samples of machine plugins (C). 7. Basic emulation of HTC ASIC3 peripheral controller, used in the number of Compaq/HP/HTC ARM PDAs (iPAQ h3900, iPAQ h4000, iPAQ hx4700, HTC Universal, etc.), written in Python. 8. Emulation of HP iPAQ h4000 PDA (main PDA features): screen, touchscreen, buttons, SD controller - written in Python. The archive (pyqemu-1.0.tar.gz) contains all materials above together with README describing how to make it run. For iPAQ h4000 emulation, sample kernel/userspace images are available in images-h4000.tar.bz2. This project was developed under auspices of Handhelds org to facilitate development of emulations of PDA hardware to help with kernel porting and debugging on those handhelds. I hope that it will be useful for this purpose, but its scope is wider and may interest other parties and open new uses for the QEMU emulator. I would like to thank following parties: Google, Inc.for the amazing GSoC program Handhelds.org for letting me to be a student on their behalf Paul Sokolovsky, my mentor, for guiding me through this work Andrzej Zaborowski on whose work on PXA/PDA, etc. emulation this work is largely based QEMU project for the best emulation platform ever Best regards, Maria Zabolotnaya.

Re: [Qemu-devel] Re: e1000 emulation
Hi Dan...! How are you doing? Okay, just a few notes: * Sorry for sending this rather badly written patch, I have loads of other stuff at the moment. I hope that it serves as a ground for further development, though. I appreciate your work here, congratulations! regards, Mulyadi
Re: [Qemu-devel] Current CVS build errors on RH9
Hi /home/wine/qemu/linux-user/syscall.c: In function `sys_tgkill': /home/wine/qemu/linux-user/syscall.c:170: `__NR_tgkill' undeclared (first use in this function) /home/wine/qemu/linux-user/syscall.c:170: (Each undeclared identifier is reported only once /home/wine/qemu/linux-user/syscall.c:170: for each function it appears in.) /home/wine/qemu/vl.c:59:24: linux/hpet.h: No such file or directory /home/wine/qemu/vl.c: In function `hpet_start_timer': /home/wine/qemu/vl.c:1222: storage size of `info' isn't known /home/wine/qemu/vl.c:1230: `HPET_IRQFREQ' undeclared (first use in this function) Got that messages too when I try to rebuild the CVS version about 3-4 days ago on my RH9 box. IMHO the reason is: no tg_kill syscall and hpet exists on RH 9. However, I successfully build the same CVS version on FC2. So, either we need to make the ./configure script detect such occassion and put the relevant ifdefs here and there, or we completely don't support those old distributions. Anybody wants to share his/her thoughts about it? regards, Mulyadi
