Philip Boulain wrote: Well done, guys. Someone's trying to build CVS QEMU on gcc4, and you're flaming them. This'll really encourage people to work on making development versions of QEMU work with gcc4. May I recommend to everybody involved to cool down a bit?

Re: [Qemu-devel] qemu on alpha
Gabriele Gorla wrote: It seems I cannot send email to the mailing list from my personal email account. Anyway... Here is what I discovered debugging the failure. Is there anyone who can direct me to the next step? Things have changed considerably in the last few weeks. The code generator is now TCG, which works currently only on x86 and x86_64 hosts. So you would need to create a TCG version for Alpha. Have a look at the tcg subdirectory in the CVS version. Thiemo
Re: [Qemu-devel] [PATCH, RFC, WIP] TCG for Qemu target Sparc32/64

It would be nice to get rid of T2 usage in std (also stda and casa/casxa) but I don't know how to pass a 64-bit value from legacy op to TCG stores and loads on a 32-bit target and host.

Looking more carefully, compile fails in : sh4-linux-user for function op_cmp_str_T0_T1 gcc optimization leads to a ret followed by a last assignement with a jump back. I guess dyngen hopes to find function epilogue as the last bytes. It's apparently the only function where it happens. I found that adding gcc option -fno-tree-dominator-opts for sh4 target avoids this (I suppose) unwanted optimization. It may be a bit brutal again ( disabling too many optims or wrong ones). May be the op_cmp_str_T0_T1 function can be rewritten to something that avoids this optimization. Am I on a better track ? This looks like the right approach to the symptoms. The real fix would be to move the sh4 target to TCG, The migration to tcg can be done gradually, fixing the immediate problem shouldn't get too involved. but for the meantime I believe this is the way to go. You can already find a lot of these unoptimization flags autodetected in the configure script, so I guess that'd be the right place for a patch. I added those as workarounds, they should rather go away than expand to cover even more flags. Thiemo

I believe Perl makes sizeof(char) checks, so there likely is some platform where sizeof(char) 1. The C standard says `When applied to an operand that has type char, unsigned char, or signed char, (or a qualified version thereof) the result is 1.' AFAIR this is C99 ... The standard maybe. But Win64 violates the C standards, too. ;) According to our department's ANSI C course, the only consistent rule is sizeof(char) = sizeof(short) = sizeof(int) = sizeof(long) without any concrete numbers. ... and this is C89.

Revision 1 of MIPS64: COP1X instructions are available when 64-bit operations (as opposed to 64-bit floating-point operations) are enabled. Revision 2 of MIPS32 and MIPS64: COP1X instructions are available when a 64-bit FPU is present (i.e. if FCR0.F64 is set). The same conditions apply to some non-COP1X instructions too, such as RECIP.fmt and RSQRT.fmt. Of course, some of the affected instructions really do require 64-bit mode, such as the paired-single ones. This part is AFAIK correct. The attached patch is one attempt to fix this. It's wrong if the description above is wrong. Because the conditions are different for different ISAs, I thought it was worth adding a MIPS_HFLAG_* to say whether COP1X (and related) instructions are available. This flag is directly associated with the nabla symbol in the MIPS32 and MIPS64 opcode tables. Any instructions that requires FR to be set (as enforced by check_cp1_64bitmode) is also affected by the nabla behaviour, so I've made check_cp1_64bitmode depend on both flags. I've added nabla checks for RECIP.S and RSQRT.S. My understanding is that the *.D forms are unpredictable when FR is clear, and that QEMU generally uses check_cp1_64bitmode for such instructions. I've therefore replaced the existing even register checks with check_cp1_64bitmode, rather than add a separate nabla test. I've replaced the single check_cp1_64bitmode calls in gen_flt3_ldst gen_flt3_arith with case-by-case checks. I've also made CABS.[SD] use nabla checks instead of check_cp1_64bitmode and added nabla checks to BC1ANY[24]. Looks reasonable to me, apart from that one misassumption. Thiemo

Hello,
I recently downloaded qemu-0.9.0 and tried to compile
it on alpha.
I was not able to get any target to compile.
I searched the mailing list but I was not able to find
any recent information on the alpha host status.
I am using gcc-3.3.6 on debian stable with upgraded
kernel
2.6.22
I have tried with gcc-3.4 and 4.1 with similar
results.
I patched the line:
#if defined (__x86_64__) || defined(__ia64) ||
defined(__alpha__)
of file dyngen-exec.h to add the alpha to the 64-bit
architectures to prevent redefinition of int64_t and
uint64_t
beside tons of warning about casting pointers to int
of different sizes I get the following two fatal
errors:
qemu-0.9.0/target-i386/ops_template.h:278: warning:
implicit declaration of function `GOTO_LABEL_PARAM'
qemu-0.9.0/target-i386/translate.c:1898: error: too
many arguments to function `gen_op_jnz_T0_label'
qemu-0.9.0/target-i386/translate.c:1900: error: too
many arguments to function `gen_op_jmp_label'
in the translate.c file the function is called with:
gen_op_jmp_label(l2);
but in gen-op.h it is defined as:
static inline void gen_op_jmp_label(void)
{
*gen_opc_ptr++ = INDEX_op_jmp_label;
}
same for gen_op_jnz_T0_label
for GOTO_LABEL_PARAM the definition is completely
missing from dyngen-exec.h (it is there for all other
host CPUs except m68k)
Unfortunately my understanding of the code is not
sufficient to do anything useful at this point.
I would really appreciate if someone could give me a
hint.
Current CVS has probably less broken alpha host support. Still, it is
unlikely to work out of the box, fixing this requires some knowledge
of alpha assembler. (E.g. for implementing a GOTO_LABEL_PARAM for alpha.)

Re: [Qemu-devel] floppy disk
Benjamin David Lunt wrote: Hi everyone, I only recently have started to use QEmu due to a request on the alt.os.development usenet group. My OS was not working on QEmu due to it would not recognize the (emulated) floppy. After a lot of testing, QEmu does not return the correct values for a Sense Interrupt command and the Status 0 byte. After looking over fdc.cc, someone has placed a hack write where it should return these values. I am just wondering if this hack is temporary or if it will be committed as code. That's the current state of the code in CVS. For a more detailed description, QEmu returns the value 0x20 while Bochs, VMware, and real hardware return the values 0xC0, 0xC1, 0xC2, and 0xC3, for each drive 1 - 4 respectively. I am asking for more information on this subject. The interrupt status handling in QEMU's FDC emulation looks bogus to me, patches to fix it are welcome. :-) Thiemo

Re: [Qemu-devel] fstat bug on armeb stll exists!
Claudio Scordino wrote: Hi all, more than one year ago we sent a patch on this mailing list to fix a problem of the fstat syscall for armeb. See http://lists.gnu.org/archive/html/qemu-devel/2006-09/msg00137.html We found the bug compiling a Linux kernel for armeb on scratchbox. Qemu seemed to ignore the fact that in big endian systems the fields st_blocks and its padding are swapped (to allow future expansion of the field,) so the fix consisted only in swapping the two fields (only in big endian systems, of course). The patch just changed qemu/linux-user/syscall_defs.h to #ifndef TARGET_WORDS_BIGENDIAN target_ulongst_blocks; target_ulong__pad4; #else target_ulong__pad4; target_ulongst_blocks; #endif AFAICS this assumption matches neither the glibc 2.6 nor the Linux 2.6.23 definitions. There is, however, an endianness difference in handling the st_dev and st_rdev fields which is not handled properly in QEMU. I think this needs a separate struct stat definition for (non-EABI) big endian ARM. Thiemo

Re: [Qemu-devel] qemu hw/ppc_oldworld.c target-ppc/cpu.h target-...
Paul Brook wrote: I think what you mean is that they work the way that ppc64 is defined, to remain compatible with ppc32. IMHO this is entirely irrelevant as we're emulating a ppc32. You could replace the high bits with garbage and nothing would ever be able to tell the difference. PowerPC is a 64 bits architecture. PowerPC 32 on 32 bits host is optimized not to compute the 32 highest bits, the same way it's allowed to cut down the GPR when implementing a CPU that would not support the 64 bits mode (but this is a tolerance, this is not the architecture is defined). No. PowerPC is defined as a 64-bit archirecure. However there is a subset of this architecture (aka ppc32) that is a complete 32-bit architecture in its own right. By your own admission, we can get away with not calculating the high 32 bit of the register. If follows that the high bits are completely meaningless. This btw. also means that the ppc32 emulation on 32-bit hosts is needlessly inefficient if the high bits are carried around. The qemu ppc32 emulation is implemented in such a way that on 64-bit hosts it looks a lot like a ppc64 implementation. However this need not, and should not be exposed to the user. OK. Those are real bugs to be fixed. I'll take a look But I'll try not to break the GPR dump. In fact, GPR should always dumped as 64 bits, even when runnig on 32 bits hosts. This would be more consistent with the specification. I disagree. qemu is implementing ppc32. Showing more than 32 bits of register is completely bogus. Any differences between a 32-bit host and a 64-bit host are a qemu bug. If you display 64 bits, then those 64 bits had better be the same when run on 32-bit hosts. I strongly agree with Paul. Thiemo

J. Mayer wrote: [snip] Showing more than 32 bits of register is completely bogus. No. It's showing the full CPU state, which can be more than what the application (or the OS, when running virtualized on a real CPU) could see. The OS cannot see the whole CPU state, but Qemu must implement more than the OS can see and is then able to dump it. 64 bits GPR is just a specific case of a general behavior. Any differences between a 32-bit host and a 64-bit host are a qemu bug. If you display 64 bits, then those 64 bits had better be the same when run on 32-bit hosts. Why ? The idea is that it costs too much to keep the whole state when running on a 32 bits host, then we act as a restricted embedded implementation. When the host CPU allows it without any extra cost, we act as the specification defines we should. This is a choice. Once again, this choice can be discussed and may be changed if I get convinced it would be better not to act this way. But this behavior is sure not bugged, it exactly follows (or may say should exactly if well implemented) the PowerPC specification. Degrading the emulation capabilities in dependence of the host capabilities with disregard of the user's requests sounds like a tremendously bad idea to me. So - If the high bits state is discoverable from guest software then it should always be emulated, independent of the host. - If the high bits state is software transparent, then it should never be emulated. Even on a 64-bit host it will reduce performance as it moves more state through the caches. Moreover, the emulation will stay architecturally correct WRT to software execution, which is, I believe, the part of the spec which actually counts for QEMU. Thiemo

If that's really the case, I'm curious why it's distributed in its binary form rather than being built at runtime. Fabrice, can you shed some light on this? Onerous cross-compiler dependencies. I think every Qemu installation should use this Qemu BIOS, the BIOS that is made for this project and not the original Bochs BIOS. Are you able to fix this in Ubuntu? Debian and Ubuntu have fairly strict policies about stuff shipped in binary form in source packages, so unless qemu is changed to build this bios at build time, that's not going to happen. One way around that would be to build additional BIOS images which use the qemu patches in the bochs package, provide them via an Architecture:all data package, and then let the Qemu package depend on that data package.
