* [REGRESSION in 3.18][PPC] PA Semi fails to boot after: of/base: Fix PowerPC address parsing hack @ 2015-03-05 22:12 Steven Rostedt 2015-03-06 4:18 ` Benjamin Herrenschmidt 0 siblings, 1 reply; 11+ messages in thread From: Steven Rostedt @ 2015-03-05 22:12 UTC (permalink / raw) To: LKML Cc: Benjamin Herrenschmidt, Grant Likely, Rob Herring, Olof Johansson, linuxppc-dev A bug in ftrace was reported to me that affects ARM and ARM64 but not x86. Looking at the code it appears to affect PowerPC as well. So I booted up my old PA Semi, to give it a try. The last time I booted it was for a 3.17 kernel. Unfortunately, for 4.0-rc2 it crashed with: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc0000000005cef88 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 PA Semi PWRficient Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 4.0.0-rc2-test #50 task: c00000003816cb60 ti: c0000000381a4000 task.ti: c0000000381a4000 NIP: c0000000005cef88 LR: c00000000007c1a0 CTR: c00000000007c184 REGS: c0000000381a7a00 TRAP: 0300 Not tainted (4.0.0-rc2-test) MSR: 9000000000009032 <SF,HV,EE,ME,IR,DR,RI> CR: 22000028 XER: 00000000 DAR: 0000000000000000 DSISR: 40000000 SOFTE: 0 GPR00: c00000000007c1a0 c0000000381a7c80 c000000000af4b98 0000000000000001 GPR04: 0000000000000000 0000000000000000 00000000000004ba 000000003d6de000 GPR08: 0100000000000000 0000000000000000 c0000000381a4080 0000000000000000 GPR12: 0000000024044042 c00000000ffff300 ffffffffffffffed 0000000000000000 GPR16: c000000000afb920 c0000000381a4000 c0000000009ad648 c0000000009ae580 GPR20: c0000000381a4080 c0000000381a4000 c0000000381a4080 c0000000381a4000 GPR24: c0000000381a4000 c0000000381a4000 c000000000afb880 c0000000381a4000 GPR28: c0000000009f8790 0000000000000000 c0000000381a4000 c000000000b02168 NIP [c0000000005cef88] .check_astate+0x28/0x50 LR [c00000000007c1a0] sleep_common+0x14/0x74 Call Trace: [c0000000381a7c80] [c000000000afb880] 0xc000000000afb880 (unreliable) [c0000000381a7cf0] [c00000000007c1a0] sleep_common+0x14/0x74 [c0000000381a7d30] [c0000000000130f0] .arch_cpu_idle+0x70/0x160 [c0000000381a7db0] [c0000000000d6660] .cpu_startup_entry+0x320/0x5a0 [c0000000381a7ee0] [c000000000034570] .start_secondary+0x290/0x2c0 [c0000000381a7f90] [c000000000008bfc] start_secondary_prolog+0x10/0x14 Instruction dump: 60000000 60000000 7c0802a6 f8010010 f821ff91 60000000 60000000 3d220003 39296870 a86d0038 e9290010 7c0004ac <7c004c2c> 0c000000 4c00012c 5463103a ---[ end trace 40e864a431826b26 ]--- I kicked off a ktest bisect, and it came down to this commit: commit 746c9e9f92dde2789908e51a354ba90a1962a2eb Author: Benjamin Herrenschmidt <benh@kernel.crashing.org> Date: Fri Nov 14 17:55:03 2014 +1100 of/base: Fix PowerPC address parsing hack When I revert this from v4.0-rc2, I can successfully boot my PA Semi again. -- Steve ^ permalink raw reply [flat|nested] 11+ messages in thread

Oh I was not expecting a new FW, I was mostly wondering whether Steven had the latest one since I *think* Michael has been testing with the PA board we got here and didn't see that problem ... anyway, I'll check with him early next week and clean up / submit that patch.

Yeah I have been testing semi-regularly. 4.0-rc2 boots fine on mine. But mine is an Athena, Steve's is an Electra. So they're not identical. Mine is running: CFE version PAS-2.0.29 for ATHENA (64bit,MP,BE,PPC) Build Date: Mon Jun 30 11:47:25 PDT 2008 (mpl@mitch-1) Steve is your CFE older than that?

So they're not identical. I have a chitra in my boot farm, so I run every build I do on it. I have not hit it either, which confused me. Turns out that Steven's machine boots with idle=doze, which is the part that makes all the difference. FWIW, the three machines have roughly these diffs: * Electra: First development/eval board. Funky USB on localbus, plenty of PCI-e. Two GigE, one 10GigE XAUI. CompactFlash and IDE on localbus too. Usually shipped with a PCI-e SATA card and a USB card. * Chitra: Second edition dev/eval board. Moved SATA and USB on-board, and removed some of the localbus hardware. Might have routed three GigE out instead of 2, can't remember. * Athena: Never released board with a smaller package chip, there's only a few of these around. Can't comment too much on the specifics, but it's similar to Chitra, and the silicon is the same. > Mine is running: > > CFE version PAS-2.0.29 for ATHENA (64bit,MP,BE,PPC) > Build Date: Mon Jun 30 11:47:25 PDT 2008 (mpl@mitch-1) > > Steve is your CFE older than that? > > Olof do you remember if that version or something newer is available for > Electra? That looks about as new as they come. My board runs a .29 too. -Olof ^ permalink raw reply [flat|nested] 11+ messages in thread
