2024-01-12octeontx2-af: CN10KB: Fix FIFO length calculation for RPM2Nithin Dabilpuram1-1/+6
RPM0 and RPM1 on the CN10KB SoC have 8 LMACs each, whereas RPM2 has only 4 LMACs. Similarly, the RPM0 and RPM1 have 256KB FIFO, whereas RPM2 has 128KB FIFO. This patch fixes an issue with improper TX credit programming for the RPM2 link.

2024-01-04octeontx2-af: Re-enable MAC TX in otx2_stop processingNaveen Mamindlapalli3-1/+25
During QoS scheduling testing with multiple strict priority flows, the netdev tx watchdog timeout routine is invoked when a low priority QoS queue doesn't get a chance to transmit the packets because other high priority flows are completely subscribing the transmit link. The netdev tx watchdog timeout routine will stop MAC RX and TX functionality in otx2_stop() routine before cleanup of HW TX queues which results in SMQ flush errors because the packets belonging to low priority queues will never gets flushed since MAC TX is disabled. This patch fixes the issue by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed properly.

2024-01-04octeontx2-af: Always configure NIX TX link credits based on max frame sizeNaveen Mamindlapalli1-107/+3
Currently the NIX TX link credits are initialized based on the max frame size that can be transmitted on a link but when the MTU is changed, the NIX TX link credits are reprogrammed by the SW based on the new MTU value. Since SMQ max packet length is programmed to max frame size by default, there is a chance that NIX TX may stall while sending a max frame sized packet on the link with insufficient credits to send the packet all at once. This patch avoids stall issue by not changing the link credits dynamically when the MTU is changed.

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

2023-12-06octeontx2-af: Adjust Tx credits when MCS external bypass is disabledNithin Dabilpuram5-1/+25
When MCS external bypass is disabled, MCS returns additional 2 credits(32B) for every packet Tx'ed on LMAC. To account for these extra credits, NIX_AF_TX_LINKX_NORM_CREDIT.CC_MCS_CNT needs to be configured as otherwise NIX Tx credits would overflow and will never be returned to idle state credit count causing issues with credit control and MTU change. This patch fixes the same by configuring CC_MCS_CNT at probe time for MCS enabled SoC's Fixes: bd69476e86fc ("octeontx2-af: cn10k: mcs: Install a default TCAM for normal traffic") Signed-off-by: Nithin Dabilpuram <ndabilpuram@marvell.com> Signed-off-by: Geetha sowjanya <gakula@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Reviewed-by: Wojciech Drewek <wojciech.drewek@intel.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Inquire firmware on supported offloads, as well as convey offloads enabled dynamically to firmware. New control net API functionality is required for the above. Implement control net API framework for offloads. Additionally, fetch/insert offload metadata from hardware RX/TX buffer respectively during receive/transmit. Currently supported offloads include checksum and TSO.

2023-12-06net: mvmdio: Avoid excessive sleeps in polled modeTobias Waldekranz1-37/+16
Before this change, when operating in polled mode, i.e. no IRQ is available, every individual C45 access would be hit with a 150us sleep after the bus access. For example, on a board with a CN9130 SoC connected to an MV88X3310 PHY, a single C45 read would take around 165us: root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003 Performed 1000 reads in 165ms By replacing the long sleep with a tighter poll loop, we observe a 10x increase in bus throughput: root@infix:~$ mdio f212a600.mdio-mii mmd 4:1 bench 0xc003 Performed 1000 reads in 15ms Signed-off-by: Tobias Waldekranz <tobias@waldekranz.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Tested-by: Andrew Lunn <andrew@lunn.ch> Link: https://lore.kernel.org/r/20231204100811.2708884-3-tobias@waldekranz.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-12-05octeontx2-af: fix a use-after-free in rvu_npa_register_reportersZhipeng Lu1-4/+1
The rvu_dl will be freed in rvu_npa_health_reporters_destroy(rvu_dl) after the create_workqueue fails, and after that free, the rvu_dl will be translate back through rvu_npa_health_reporters_create, rvu_health_reporters_create, and rvu_register_dl. Finally it goes to the err_dl_health label, being freed again in rvu_health_reporters_destroy(rvu) by rvu_npa_health_reporters_destroy. In the second calls of rvu_npa_health_reporters_destroy, however, it uses rvu_dl->rvu_npa_health_reporter, which is already freed at the end of rvu_npa_health_reporters_destroy in the first call. So this patch prevents the first destroy by instantly returning -ENONMEN when create_workqueue fails. In addition, since the failure of create_workqueue is the only entrence of label err, it has been integrated into the error-handling path of create_workqueue.
