What: /sys/kernel/debug/pcie_ptm_*/t4 Date: May 2025 Contact: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Description: (RO) PTM T4 timestamp in nanoseconds. Applicable only for Endpoint controllers. What: /sys/kernel/debug/pcie_ptm_*/context_update Date: May 2025 Contact: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Description: (RW) Control the PTM context update mode. Applicable only for Endpoint controllers. Following values are supported: * auto = PTM context auto update trigger for every 10ms * manual = PTM context manual update. Writing 'manual' to this file triggers PTM context update (default) What: /sys/kernel/debug/pcie_ptm_*/context_valid Date: May 2025 Contact: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Description: (RW) Control the PTM context validity (local clock timing). Applicable only for Root Complex controllers. PTM context is invalidated by hardware if the Root Complex enters low power mode or changes link frequency. Following values are supported: * 0 = PTM context invalid (default) * 1 = PTM context valid |
