Re: [PATCH v4 00/21] Add Qualcomm Minidump kernel driver related support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 





Hi Mukesh,

For IPQ chipsets, for the crashdump to work, we need the below patch

firmware: scm: Modify only the download bits in TCSR register

can you post the below patches separately? Looks like minidump will take some time and also I don't see any dependencies for these to go along with the minidump. Given that, will it be possible to post the below patches separately?

   firmware: qcom_scm: provide a read-modify-write function
   pinctrl: qcom: Use qcom_scm_io_update_field()
   firmware: scm: Modify only the download bits in TCSR register

Do let us know if we can take these patches and post it separately.

Yes, we can post this separately.
