2022-11-02e1000e: Remove unnecessary use of kmap_atomic()Anirudh Venkataramanan1-15/+5
alloc_rx_buf() allocates ps_page->page and buffer_info->page using either GFP_ATOMIC or GFP_KERNEL. Memory allocated with GFP_KERNEL/GFP_ATOMIC can't come from highmem and so there's no need to kmap() them. Just use page_address(). I don't have access to a 32-bit system so did some limited testing on qemu (qemu-system-i386 -m 4096 -smp 4 -device e1000e) with a 32-bit Debian 11.04 image.

2022-11-02e1000e: Add e1000e trace moduleSasha Neftin3-0/+49
Add tracepoints to the driver via a new file e1000e_trace.h and some new trace calls added in interesting places in the driver. Add some tracing for s0ix flows to help in a debug of shared resources with the CSME firmware. The idea here is that tracepoints have such low performance cost when disabled that we can leave these in the upstream driver. Performance not affected, and this can be very useful for debugging and adding new trace events to paths in the future.

2022-10-31ptp: introduce helpers to adjust by scaled parts per millionJacob Keller1-13/+3
Many drivers implement the .adjfreq or .adjfine PTP op function with the same basic logic: 1. Determine a base frequency value 2. Multiply this by the abs() of the requested adjustment, then divide by the appropriate divisor (1 billion, or 65,536 billion). 3. Add or subtract this difference from the base frequency to calculate a new adjustment. A few drivers need the difference and direction rather than the combined new increment value. I recently converted the Intel drivers to .adjfine and the scaled parts per million (65.536 parts per billion) logic. To avoid overflow with minimal loss of precision, mul_u64_u64_div_u64 was used. The basic logic used by all of these drivers is very similar, and leads to a lot of duplicate code to perform the same task. Rather than keep this duplicate code, introduce diff_by_scaled_ppm and adjust_by_scaled_ppm. These helper functions calculate the difference or adjustment necessary based on the scaled parts per million input. The diff_by_scaled_ppm function returns true if the difference should be subtracted, and false otherwise. Update the Intel drivers to use the new helper functions. Other vendor drivers will be converted to .adjfine and this helper function in the following changes.

2022-07-28e1000e: convert .adjfreq to .adjfineJacob Keller3-10/+11
The PTP implementation for the e1000e driver uses the older .adjfreq method. This method takes an adjustment in parts per billion. The newer .adjfine implementation uses scaled_ppm. The use of scaled_ppm allows for finer grained adjustments and is preferred over using the older implementation. Make use of mul_u64_u64_div_u64 in order to handle possible overflow of the multiplication used to calculate the desired adjustment to the hardware increment value.

The e1000e_phc_adjfreq function validates that the input delta is within the maximum range. This is already handled by the core PTP code and this is a duplicate and thus unnecessary check. It also complicates refactoring to use the newer .adjfine implementation, where the input is no longer specified in parts per billion. Remove the range validation check.

Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed.

2021-07-20e1000e: Add polling mechanism to indicate CSME DPG exitSasha Neftin3-0/+26
Per guidance from the CSME architecture team, it may take up to 1 second for unconfiguring dynamic power gating mode. Practically it can take more time. Wait up to 2.5 seconds to indicate dynamic power gating exit from the S0ix configuration. Detect scenarios that take more than 1 second but less than 2.5 seconds will emit warning message.
