2024-09-10net: ftgmac100: Enable TX interrupt to avoid TX timeoutJacky Chou
Currently, the driver only enables RX interrupt to handle RX packets and TX resources. Sometimes there is not RX traffic, so the TX resource needs to wait for RX interrupt to free. This situation will toggle the TX timeout watchdog when the MAC TX ring has no more resources to transmit packets. Therefore, enable TX interrupt to release TX resources at any time. When I am verifying iperf3 over UDP, the network hangs. Like the log below. root# iperf3 -c 192.168.100.100 -i1 -t10 -u -b0 Connecting to host 192.168.100.100, port 5201 [ 4] local 192.168.100.101 port 35773 connected to 192.168.100.100 port 5201 [ ID] Interval Transfer Bandwidth Total Datagrams [ 4] 0.00-20.42 sec 160 KBytes 64.2 Kbits/sec 20 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 [ 4] 20.42-20.42 sec 0.00 Bytes 0.00 bits/sec 0 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 4] 0.00-20.42 sec 160 KBytes 64.2 Kbits/sec 0.000 ms 0/20 (0%) [ 4] Sent 20 datagrams iperf3: error - the server has terminated The network topology is FTGMAC connects directly to a PC. UDP does not need to wait for ACK, unlike TCP. Therefore, FTGMAC needs to enable TX interrupt to release TX resources instead of waiting for the RX interrupt.

2024-09-10drm/nouveau/fb: restore init() for ramgp102Ben Skeggs
init() was removed from ramgp102 when reworking the memory detection, as it was thought that the code was only necessary when the driver performs mclk changes, which nouveau doesn't support on pascal. However, it turns out that we still need to execute this on some GPUs to restore settings after DEVINIT, so revert to the original behaviour. v2: fix tags in commit message, cc stable Closes: https://gitlab.freedesktop.org/drm/nouveau/-/issues/319 Fixes: 2c0c15a22fa0 ("drm/nouveau/fb/gp102-ga100: switch to simpler vram size detection method") Cc: stable@vger.kernel.org # 6.6+ Signed-off-by: Ben Skeggs <bskeggs@nvidia.com> Signed-off-by: Danilo Krummrich <dakr@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240904232418.8590-1-bskeggs@nvidia.com
2024-09-10octeontx2-af: Modify SMQ flush sequence to drop packetsNaveen Mamindlapalli
The current implementation of SMQ flush sequence waits for the packets in the TM pipeline to be transmitted out of the link. This sequence doesn't succeed in HW when there is any issue with link such as lack of link credits, link down or any other traffic that is fully occupying the link bandwidth (QoS). This patch modifies the SMQ flush sequence to drop the packets after TL1 level (SQM) instead of polling for the packets to be sent out of RPM/CGX link.

2024-09-10iommu/amd: Add kernel parameters to limit V1 page-sizesJoerg Roedel
Add two new kernel command line parameters to limit the page-sizes used for v1 page-tables: nohugepages - Limits page-sizes to 4KiB v2_pgsizes_only - Limits page-sizes to 4Kib/2Mib/1GiB; The same as the sizes used with v2 page-tables This is needed for multiple scenarios. When assigning devices to SEV-SNP guests the IOMMU page-sizes need to match the sizes in the RMP table, otherwise the device will not be able to access all shared memory. Also, some ATS devices do not work properly with arbitrary IO page-sizes as supported by AMD-Vi, so limiting the sizes used by the driver is a suitable workaround. All-in-all, these parameters are only workarounds until the IOMMU core and related APIs gather the ability to negotiate the page-sizes in a better way.

2024-09-10net: lan966x: use library helper for freeing tx buffersDaniel Machon
The library has the helper fdma_free_phys() for freeing physical FDMA memory. Use it in the exit path. Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Reviewed-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2024-09-10net: lan966x: use FDMA library for adding DCB's in the tx pathDaniel Machon
Use the fdma_dcb_add() function to add DCB's in the tx path. This gets rid of the open-coding of nextptr and dataptr handling and leaves it to the library.

2024-09-10net: lan966x: use the FDMA library for allocation of tx buffersDaniel Machon
Use the two functions: fdma_alloc_phys() and fdma_dcb_init() for rx buffer allocation and use the new buffers throughout. In order to replace the old buffers with the new ones, we have to do the following refactoring: - use fdma_alloc_phys() and fdma_dcb_init() - replace the variables: tx->dma, tx->dcbs and tx->curr_entry with the equivalents from the FDMA struct. - add lan966x_fdma_tx_dataptr_cb callback for obtaining the dataptr. - Initialize FDMA struct values.

2024-09-10net: lan966x: replace a few variables with new equivalent onesDaniel Machon
Replace the old rx and tx variables: channel_id, FDMA_DCB_MAX, FDMA_RX_DCB_MAX_DBS, FDMA_TX_DCB_MAX_DBS, dcb_index and db_index with the equivalents from the FDMA rx and tx structs. These variables are not entangled in any buffer allocation and can therefore be replaced in advance.
