hi
i m comparing the trace of execution of reconstruction of trace instruction of
a code running in real board and the trace of the same code running in qemu ..
and i found that there is some function not called in the reconstruction of
qemu trace ..
i guess that qemu do some optimization or th
im working in the reconstitution of execution trace informations of the guest
processor in qemu and i need an approximative time of execution of every
translation block by the guest processor .
can you give me some hints about that ? thank you
hi i m using the log in_asm to get the assembly code of TB so when i searched
inside qemu i find that the function "log_target_disas its the responsible to
display assembly instruction but the problem that i did not find how really it
works because i need to get all the branch address
thank you
hi
im trying to trace Translation bloks and i guess that this function its the
responsible for print the trace informations
qemu_log_mask_and_addr(CPU_LOG_EXEC, itb->pc, "Trace %p [%d: " TARGET_FMT_lx "]
%s\n", itb->tc_ptr, cpu->cpu_index, itb->pc, lookup_symbol(itb->pc));
but really i didn't u
hi
Im using the gdbserver to know what qemu exactly doing..in theory i find that
cpu_tb_exec () is the function that execute TB but when i put a break point in
this function the qemu did not stop..this have relation with the inline
function or not
hi i have a problem when i try to join IRC channel #qemu can someone help ?
hi i want to know where the translation of branch instruction (arm) to tcg code
is located thanks
i used simple trace back end to trace guest code running in qemu but when i
tried to recompile and disable this trace i have always this problem
undefined reference to `trace_record_write_u64'
thanks for your help
hi
i search the pc of tb in the guest code i used the function
cpu_restore_state_from_tb in cpu_exec_tb but the searching pc take 0 value can
someone explain me why searching_pc is 0 or give me some hints
thanks
| favorite | am trying to find the translation block adress of QEMU . And I
have a question about the adress pointer of translation block . void
gen_intermediate_code(CPUARMState *env, TranslationBlock *tb)
it is the address of the last translation block found in the cache or that will
be trans
I am trying to understand the block chaining of QEMU. And I have a question
about the branch direction of each executed TBs. Suppose the TB#1 has been
executed now, and find the next_tb (TB#2). Then we know the direction is
TB#1--->TB#2 and store the chain in code cache for speedup the executio
hi
i need help because im really blocked in my educational project
my problem is i how can i find the adress of the instruction of the end of
translation block in qemu (usually it's branch instruction) or the adress of
the translation block
your advice will be very helpful for me .thanks

hi
im using qemu and i run in it a sample application of addition.c that do a+b=c
in order to implement a trace for the code execution od addition.c i want to
get adresses of transaltion block
thank you for the help
hi
in my academic project i needed to know how qemu exactly translate an arm
instruction to the host assembly (in my case x86) so if you can help me to know
the function in the source code of qemu that tdo this work
thank you
hi
hello
im an engineer student and im working in my educational project implementation
of hardware tinstructions trace in qemu
i don't know where i can implement it in qemu
thanks
hi
