Re: [Crash-utility] Updating PPC

Hello Dave, I attach patches which are updating powerpc based on linux-2.6.27. Please review them. Following updates have been done but some of them could not test yet because of constraints in environment. (Non-SMP powerpc virtual machine of qemu can only use) - Get rid of __func__. symbols (patch 0001) This patch can delete such symbols from command output like crash> sym -l | grep __func__ -m 3 c03604ac (r) __func__.21434 c0360500 (r) __func__.21333 c0360508 (r) __func__.21309 - Minor updates (patch 0002/0003/0004) ppc_processor_speed() support "ibm,extended-clock-frequency" [Not tested] ppc_get_smp_cpus() can return correct cpu numbers on SMP [Not tested] "bt", "mach" can handle (tt->flags & IRQSTACKS) [Not tested] - Enhancement of "bt" (patch 0005/0006/0007/0008) Detect exeption frame of linux-2.6 style ("bt" can dispaly '+' parts of below) Some functions are cleanuped with ppc64's. * Link Register of nested exception frame could not be tested. This may require the exception in kernel mode like oops but can not try kernel dump for a while... crash> bt 1 PID: 1 TASK: c8818000 CPU: 0 COMMAND: "init" #0 [c881da10] schedule at c0356ac4 #1 [c881da70] schedule_timeout at c0357468 #2 [c881dab0] do_select at c00c4758 #3 [c881dd90] core_sys_select at c00c4bd0 #4 [c881dee0] sys_select at c00c52b0 #5 [c881df30] ppc_select at c00053c0 #6 [c881df40] ret_from_syscall at c0011f64 + syscall [c01] exception frame: +R0: 0000008e R1: b8c11a60 R2: 48008660 R3: 0000000b +R4: b8c11cac R5: 00000000 R6: 00000000 R7: b8c11b24 +R8: 00000000 R9: 00000400 R10: 00000000 R11: 0ff24b2c +R12: 0ff1b8ec R13: 100207f0 +NIP: 0ff24b40 MSR: 0000d032 OR3: 0000000b CTR: 0ff24b2c +LR: 10005314 XER: 00000000 CCR: 24002462 MQ: 00000000 +DAR: 0ffb4cd0 DSISR: 0a000000 Syscall Result: 00000000 Still remaining the parts of PPC update and I have to setup more useful environment for the tests as soon as possible.
