support. + +Small real time trace (SmaRT) is an optional on-chip debug hardware +component that captures instruction-trace history. It stores the +address of the most recent non-sequential instructions executed into +internal buffer. + +Usually we use MetaWare debugger to enable SmaRT and display trace +information. + +This patch allows to display the decoded content of SmaRT buffer +without MetaWare debugger. It is done by extending ordinary exception +message with decoded SmaRT instruction-trace history. + +In some cases it's really useful as it allows to show pre-exception +instruction-trace which was not tainted by exception handler code, +printk code, etc... + +Nevertheless this option has negative performance impact due to +implementation as we dump SmaRT buffer content into external memory +buffer in the beginning of every slowpath exception handler code. +We choose this implementation as a compromise between performance +impact and SmaRT buffer tainting. +Although the performance impact is not really significant (according +to lmbench) we leave this option disabled by default. + +Here is th examples of user-space and kernel-space fault messages with +'ARC_SMART_TRACE' option enabled: + +User-space exception: +----------------------->8------------------------- +Exception: u_hell[101]: at 0x103a2 [off 0x103a2 in /root/u_hell, VMA: 00010000:00012000] + ECR: 0x00050200 => Invalid Write @ 0x00000000 by insn @ 0x000103a2 +SmaRT [64 entries] (U=userspace, E=exception/interrupt, R=repeated, V=valid): + dst[ 0]: ___V 0x90231dd8: smart_populate+0x0/0xcc + src[ 0]: 0x9023230c: do_page_fault+0x2c/0x2ec + dst[ 1]: ___V 0x902322e0: do_page_fault+0x0/0x2ec + src[ 1]: 0x9022e064: EV_TLBProtV+0xec/0xf0 + dst[ 2]: ___V 0x9022df78: EV_TLBProtV+0x0/0xf0 + src[ 2]: 0x9023315c: do_slow_path_pf+0x10/0x14 + dst[ 3]: ___V 0x9023314c: do_slow_path_pf+0x0/0x14 + src[ 3]: 0x902330e8: EV_TLBMissD+0x80/0xe0 + dst[ 4]: _E_V 0x90233068: EV_TLBMissD+0x0/0xe0 + src[ 4]: 0x000103a2: off 0x103a2 in /root/u_hell (VMA: 00010000:00012000) + dst[ 5]: U__V 0x00010398: off 0x10398 in /root/u_hell + src[ 5]: 0x2004f238: off 0x43238 in /lib/libuClibc-1.0.18.so (VMA: 2000c000:20072000) + dst[ 6]: U__V 0x2004f214: off 0x43214 in /lib/libuClibc-1.0.18.so + src[ 6]: 0x20049a82: off 0x3da82 in /lib/libuClibc-1.0.18.so +...[snip]... +----------------------->8------------------------- + +Kernel-space exception: +----------------------->8------------------------- +Exception: at dw_mci_probe+0x12/0x954: + ECR: 0x00050100 => Invalid Read @ 0x00000004 by insn @ 0x905e7ca2 +SmaRT [64 entries] (U=userspace, E=exception/interrupt, R=repeated, V=valid): + dst[ 0]: ___V 0x90231dd8: smart_populate+0x0/0xcc + src[ 0]: 0x9023230c: do_page_fault+0x2c/0x2ec + dst[ 1]: ___V 0x902322e0: do_page_fault+0x0/0x2ec + src[ 1]: 0x9022e064: EV_TLBProtV+0xec/0xf0 + dst[ 2]: ___V 0x9022e00c: EV_TLBProtV+0x94/0xf0 + src[ 2]: 0x9022e004: EV_TLBProtV+0x8c/0xf0 + dst[ 3]: ___V 0x9022df78: EV_TLBProtV+0x0/0xf0 + src[ 3]: 0x9023315c: do_slow_path_pf+0x10/0x14 + dst[ 4]: ___V 0x9023314c: do_slow_path_pf+0x0/0x14 + src[ 4]: 0x902330a4: EV_TLBMissD+0x3c/0xe0 + dst[ 5]: _E_V 0x90233068: EV_TLBMissD+0x0/0xe0 + src[ 5]: 0x905e7ca2: dw_mci_probe+0x12/0x954 + dst[ 6]: ___V 0x905e7c90: dw_mci_probe+0x0/0x954 + src[ 6]: 0x905ea61c: dw_mci_pltfm_probe+0xa8/0xc4 + dst[ 7]: ___V 0x905ea5f4: dw_mci_pltfm_probe+0x80/0xc4 + src[ 7]: 0x904a9b2e: devm_ioremap_resource+0x4e/0x12c + dst[ 8]: ___V 0x904a9b1e: devm_ioremap_resource+0x3e/0x12c + src[ 8]: 0x904a9bc0: devm_ioremap_resource+0xe0/0x12c + dst[ 9]: ___V 0x904a9bbc: devm_ioremap_resource+0xdc/0x12c + src[ 9]: 0x9075a3b0: _raw_spin_unlock_irqrestore+0x28/0x2c +...[snip]... +----------------------->8------------------------- + +The number of SmaRT buffer lines to record/display can be configured +in runtime via '/proc/sys/smart_trace/entries' procfs option. +SmaRT can be suspended in runtime by setting +'/proc/sys/smart_trace/entries' to 0. + +The code was written in such a way to achieve minimal interference +with MetaWare SmaRT support: + * SmaRT is disabled only for small amount of time in smart_populate + function. + * SmaRT enable/disable via MetaWare doesn't lead to any serious + issues (SmaRT disable via MetaWare may lead to last SmaRT + record to be invalid, though) + +NOTE: +this RFC has prerequisite: + http://patchwork.ozlabs.org/patch/986820/ + +Changes RFCv1->RFCv2: + * Changes in output display: + * Only print VMAs if they are changed. + * Split entry for two lines and print source and destination + addresses on different lines. + * Add procfs options to configure/suspend SmaRT in runtime. + * Add SmaRT version check.
