Subject: [Qemu-devel] [PATCH V9 0/5] target-ppc: Add support for dumping guest memory using qemu gdb server
Date: Tue, 28 Jan 2014 13:29:58 +0530	[thread overview]
Message-ID: <1390896003-3195-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)

Hi,


This patch series implement support for dumping guest memory using qemu gdb server. The last patch also enable qemu monitor command dump-guest-memory

With this patch series we can now do

(gdb) x/4i htab_call_hpte_insert1
   0xc0000000000470d8 <.htab_call_hpte_insert1>:        bl      0xc0000000000470d8 <.htab_call_hpte_insert1>
   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
(gdb) target remote localhost:1234

(gdb) x/4i 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
(gdb)

NOTE: We still don't support inserting breakpoints.

Before Fix:
(qemu) memsave 0xc0000000000470d8 10 memdump
Invalid parameter 'addr'
(qemu)

After fix:

(qemu)  memsave 0xc0000000000470d8 10 memdump
(qemu)

Changes from V8:
* Add hpte store support. Currently we don't have any user for this.
