AFAIK we don't but at least we're sure with this patch, it successfully boots on: - db410c - db820c - rb3 - hdk8150 - rb5 - hdk8350 - hdk8450 - qrd8550 - hdk8550 - qrd8650 - hdk8650 => https://git.codelinaro.org/linaro/qcomlt/ci/staging/cdba-tester/-/pipelines/91268 Without this change it crashes on rb3 & hdk8150: - https://git.codelinaro.org/linaro/qcomlt/ci/staging/cdba-tester/-/jobs/152722#L749 - https://git.codelinaro.org/linaro/qcomlt/ci/staging/cdba-tester/-/jobs/152723#L838 Neil > > As Bartosz says, we booted RB3 successfully with an earlier version of > this series, what changed? > > Regards, > Bjorn > >> NULL >> }; >> >> >> --- >> base-commit: 82e4255305c554b0bb18b7ccf2db86041b4c8b6e >> change-id: 20240704-shmbridge-blacklist-021bd97b8a93 >> >> Best regards, >> -- >> Dmitry Baryshkov <dmitry.baryshkov@linaro.org> >>

The SHM bridge makes the Qualcomm RB3 and SM8150-HDK reset while probing the RMTFS (in qcom_scm_assign_mem()). Blacklist the SHM Bridge on corresponding platforms using SoC-level compat string. If later it's found that the bad behaviour is limited just to the particular boards rather than SoC, the compat strings can be adjusted.
