Annotated Snippet
What: /sys/class/accel/accel<n>/device/armcp_kernel_ver
Date: Jan 2019
KernelVersion: 5.1
Contact: ogabbay@kernel.org
Description: Version of the Linux kernel running on the device's CPU.
Will be DEPRECATED in Linux kernel version 5.10, and be
replaced with cpucp_kernel_ver
What: /sys/class/accel/accel<n>/device/armcp_ver
Date: Jan 2019
KernelVersion: 5.1
Contact: ogabbay@kernel.org
Description: Version of the application running on the device's CPU
Will be DEPRECATED in Linux kernel version 5.10, and be
replaced with cpucp_ver
What: /sys/class/accel/accel<n>/device/clk_max_freq_mhz
Date: Jun 2019
KernelVersion: 5.7
Contact: ogabbay@kernel.org
Description: Allows the user to set the maximum clock frequency, in MHz.
The device clock might be set to lower value than the maximum.
The user should read the clk_cur_freq_mhz to see the actual
frequency value of the device clock. This property is valid
only for the Gaudi ASIC family
What: /sys/class/accel/accel<n>/device/clk_cur_freq_mhz
Date: Jun 2019
KernelVersion: 5.7
Contact: ogabbay@kernel.org
Description: Displays the current frequency, in MHz, of the device clock.
This property is valid only for the Gaudi ASIC family

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
