Date: Wed, 13 Mar 2024 12:42:16 +0530 [thread overview]
Message-ID: <20240313071218.729-1-sthanneeru.opensrc@micron.com> (raw)
From: Srinivasulu Thanneeru <sthanneeru.opensrc@micron.com>
Add support to expose following mailbox commands to userspace
for clearing and populating the Vendor debug log in certain
scenarios, allowing for the aggregation of results over time.
1. CXL r3.1 8.2.9.5.3 Get Log Capabilities.
2. CXL r3.1 8.2.9.5.4 Clear Log commands.
3. CXL r3.1 8.2.9.5.6 Get Supported Logs Sub-List.

Changes in v3:
- 'Component State Dump log' has several caveats for ioctl()
not being a suitable ABI as pointed in v2.(Dan Williams)
- Remove Component State Dump from Clear log filter.
- Implement a seperate patch(yet to do) to address issues as pointed in v2.
- Link to v2:
https://lore.kernel.org/linux-mm/65e631951ff61_b62b294e1@dwillia2-mobl3.amr.corp.intel.com.notmuch/
Changes in v2:
Suggested by Jonathan Cameron:
- Add description for exposing these mailbox log commands to ioctl.
- Create separate patch for 'Clear log'.
- Restrict the ‘Clear log’ action to only apply to
Vendor debug logs and Component state dump logs.
- Rename get log sublist to get supported log sublist.
- Link to v1: https://lore.kernel.org/linux-mm/20240207103634.199-1-sthanneeru.opensrc@micron.com/
