2025-01-06octeontx2-pf: mcs: Remove dead code and semi-colon from rsrc_name()Nihar Chaithanya
Every case in the switch-block ends with return statement, and the default: branch handles the cases where rsrc_type is invalid and returns "Unknown", this makes the return statement at the end of the function unreachable and redundant. The semi-colon is not required after the switch-block's curly braces. Remove the semi-colon after the switch-block's curly braces and the return statement at the end of the function. This issue was reported by Coverity Scan.

2024-11-26octeontx2-af: Quiesce traffic before NIX block resetHariprasad Kelam
During initialization, the AF driver resets all blocks. The RPM (MAC) block and NIX block operate on a credit-based model. When the NIX block resets during active traffic flow, it doesn't release credits to the RPM block. This causes the RPM FIFO to overflow, leading to receive traffic struck. To address this issue, the patch introduces the following changes: 1. Stop receiving traffic at the MAC level during AF driver initialization. 2. Perform an X2P reset (prevents RXFIFO of all LMACS from pushing data) 3. Reset the NIX block. 4. Clear the X2P reset and re-enable receiving traffic.

2024-11-26octeontx2-af: RPM: Fix low network performanceHariprasad Kelam
Low network performance is observed even on RPMs with larger FIFO lengths. The cn10kb silicon has three RPM blocks with the following FIFO sizes: -------------------- | RPM0 | 256KB | | RPM1 | 256KB | | RPM2 | 128KB | -------------------- The current design stores the FIFO length in a common structure for all RPMs (mac_ops). As a result, the FIFO length of the last RPM is applied to all RPMs, leading to reduced network performance. This patch resolved the problem by storing the fifo length in per MAC structure (cgx).

2024-11-03dim: pass dim_sample to net_dim() by referenceCaleb Sander Mateos
net_dim() is currently passed a struct dim_sample argument by value. struct dim_sample is 24 bytes. Since this is greater 16 bytes, x86-64 passes it on the stack. All callers have already initialized dim_sample on the stack, so passing it by value requires pushing a duplicated copy to the stack. Either witing to the stack and immediately reading it, or perhaps dereferencing addresses relative to the stack pointer in a chain of push instructions, seems to perform quite poorly. In a heavy TCP workload, mlx5e_handle_rx_dim() consumes 3% of CPU time, 94% of which is attributed to the first push instruction to copy dim_sample on the stack for the call to net_dim(): // Call ktime_get() 0.26 |4ead2: call 4ead7 <mlx5e_handle_rx_dim+0x47> // Pass the address of struct dim in %rdi |4ead7: lea 0x3d0(%rbx),%rdi // Set dim_sample.pkt_ctr |4eade: mov %r13d,0x8(%rsp) // Set dim_sample.byte_ctr |4eae3: mov %r12d,0xc(%rsp) // Set dim_sample.event_ctr 0.15 |4eae8: mov %bp,0x10(%rsp) // Duplicate dim_sample on the stack 94.16 |4eaed: push 0x10(%rsp) 2.79 |4eaf1: push 0x10(%rsp) 0.07 |4eaf5: push %rax // Call net_dim() 0.21 |4eaf6: call 4eafb <mlx5e_handle_rx_dim+0x6b> To allow the caller to reuse the struct dim_sample already on the stack, pass the struct dim_sample by reference to net_dim().
