[Qemu-devel] [PATCH 0/3] target-ppc: Add support for dumping guest memory using qemu gdb server

[Aneesh Kumar K.V]

Hi,

This patch series implement support for dumping guest memory using qemu gdb 
server.

Without this patch we would get.


(gdb) x/10 do_fork
     0xc000000000098660 <do_fork>:   Cannot access memory at address 
0xc000000000098660
(gdb)

With this patch series we can now do

(gdb) target remote localhost:1234
Remote debugging using localhost:1234
.plpar_hcall_norets () at arch/powerpc/platforms/pseries/hvCall.S:119
119             HCALL_INST_POSTCALL_NORETS
.....
.....
(gdb) x/10i htab_call_hpte_insert1
   0xc0000000000470d8 <.htab_call_hpte_insert1>:        bl      
0xc00000000005f8f0 <pSeries_lpar_hpte_insert>
   0xc0000000000470dc <.htab_call_hpte_insert1+4>:      cmpdi   r3,0
   0xc0000000000470e0 <.htab_call_hpte_insert1+8>:      bge     
0xc000000000047190 <htab_pte_insert_ok>
   0xc0000000000470e4 <.htab_call_hpte_insert1+12>:     cmpdi   r3,-2


NOTE: We still don't support inserting breakpoints.
