XO-1.75/Kernel/Testing

Kernel developers, put your new kernel in a new section here. Latest at top. Testers place links to reports indented under the kernel.

5ba0b446 - arm-3.0-wip-wfi

• olpc-ec: allow unknown commands to be executed
• test dependencies: EC logging (S7), kernel logging with EC debug enabled ("echo 1 > /sys/module/olpc_ec_1_75/parameters/ec_debug").
• purpose: improve EC driver; fewer (or no?) races/crashes..
• testing by
  • Samuel Greenfeld
    • C1 SKU 201 EC communications failure (#3), OLS runin disabled, Q4C11 modified EC code ecimage-0.3.07pgf-668.bin. host ec

ff199462 - arm-3.0-wip-wfi

• olpc-ec: ensure gpio cmd is left low if something screws up
• EC logged in S7
• Still has FIQ debugger
• Should help reset EC bus to avoid subsequent failures after the first command fails.
• testing by
  • Samuel Greenfeld
    • C1 hang on resume (#3), OLS runin disabled, Q4C11 normal EC code host [1]
    • C1 hang on resume (#6), OLS runin disabled, Q4C11 normal EC code
    • C1 hang on resume (#3), OLS runin disabled, Q4C11 modified EC code ecimage-0.3.07pgf-668.bin host ec

3d4cf36c - arm-3.0-wip-wfi

• mmp2_fiq_debugger.c add file missing from other merge
• EC logged in S7
• This enables a FIQ debugger. Reproduce kernel hangs, then from a serial console send a Break which should drop you to a debug prompt. run bt to see what is going on.
• testing by
  • James Cameron, C1 SKU201 host (known audio problem that doesn't need to be reported again), C1 SKU202 host (known audio problem), B4, and two B1 hung, no response to BREAK. FIQ was verified as working before starting.

26f404e3 - arm-3.0-wip-wfi

• Revert "olpc-ec: don't process/ack packets when there's an underrun error"
• EC logged in S7
• further code to work around EC communications race; discussion with pgf brought up another issue, and include patch from pgf. Test that audio pop during suspend/resume is gone from jnettlet.
• testing by
  • Samuel Greenfeld
    • 3xC1 running os23 with olpc-runin-tests-0.16.7-1 installed instead of bringup build, Q4C11, all tests (2 with EC serial), 3xC1 running with battery test disabled. Test in progress.
      • 1xC1 SKU201 (#6) running aggressive (10s on/10s off) suspend failed after 15 minutes during resume, power & full battery LEDs on, all other LEDs off. All tests except the battery test were running on this unit at the time of failure. host
      • 1xC1 SKU201 (#3) running aggressive (10s on/10s off) suspend failed at a point TBD with EC communications failure and the eMMC root filesystem remounted read-only. It continued suspend & resume testing after the failure point(s). host ec
  • James Cameron
    • C1 C1 B4 B1 B1 B1, os20, runin 0.16.7, 10sec/10sec, hangs still occur one, two, audio pops during suspend and resume are still present.

7dad6c10 - arm-3.0-wip-wfi (BROKEN)

• XO-1.75: always send the suspend hint command to the EC, even on C-series
• EC logged in S7
• further code to work around EC communications race; discussion with pgf brought up another issue, and include patch from pgf.
• testing by
  • Samuel Greenfeld
    • 1xC1 SKU202 tested; logs "olpc-ec-1.75: SSP reports TX underrun" and "SSP reports RX overrun" every three seconds shortly after the kernel starts initializing. This causes the XO to never fully boot, making this kernel unusable. log with EC at S7 log with EC at S47

afa391a5 - arm-3.0-wip-wfi

• Revert "olpc-1.75: back off the hardware clock gating for MMC devices"
• EC logged in S7
• test code to work around an EC communications race; needs further work, but this should hopefully keep things from hanging.
• testing by
