2020-10-01brcmfmac: Fix warning when hitting FW crash with flow control featureWright Feng1-6/+5
Brcmfmac got warning message when hitting FW crash in TX throughput test with fcmode=2. It's caused by FMAC flushed TXQ in brcmf_sdio_bus_stop but without doing hanger slot cleanup. Therefore, we move brcmf_remove_interface before brcmf_bus_stop to make sure the hanger slot is clean when flushing TXQ.

2020-09-29net: brcmfmac: Convey allocation mode as argumentSebastian Andrzej Siewior4-14/+13
The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be seperated or the context be conveyed in an argument passed by the caller, which usually knows the context. brcmf_fweh_process_event() uses in_interrupt() to select the allocation mode GFP_KERNEL/GFP_ATOMIC. Aside of the above reasons this check is incomplete as it cannot detect contexts which just have preemption or interrupts disabled. All callchains leading to brcmf_fweh_process_event() can clearly identify the calling context. Convey a 'gfp' argument through the callchains and let the callers hand in the appropriate GFP mode. This has also the advantage that any change of execution context or preemption/interrupt state in these callchains will be detected by the memory allocator for all GFP_KERNEL allocations.

bcrmgf_netif_rx() uses in_interrupt to chose between netif_rx() and netif_rx_ni(). in_interrupt() usage in drivers is phased out.

2020-09-29net: brcmfmac: Replace in_interrupt()Sebastian Andrzej Siewior3-5/+5
brcmf_sdio_isr() is using in_interrupt() to distinguish if it is called from a interrupt service routine or from a worker thread. Passing such information from the calling context is preferred and requested by Linus, so add an argument `in_isr' to brcmf_sdio_isr() and let the callers pass the information about the calling context.

2020-09-07brcmfmac: set F2 SDIO block size to 128 bytes for BCM4329Dmitry Osipenko1-0/+4
Setting F2 block size to 128 bytes for BCM4329 allows to significantly improve RX throughput on NVIDIA Tegra20. Before this change the throughput was capped to 30 Mbit/s on Tegra, now throughput is at 40 Mbit/s, which is a maximum throughput for the BCM4329 chip. The F2 block size is borrowed from the downstream BCMDHD driver. The comment in the BCMDHD driver says that 128B improves throughput and turns out that it works for the brcmfmac as well.

This patch fixes SDHCI CRC errors during of RX throughput testing on BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the checksum problem is observed on NVIDIA Tegra20 SoCs.

The 4329 throughput drops from 40.2 Mbits/sec to 190 Kbits/sec in 2G 11n mode because the commit b41c232d33666 ("brcmfmac: reserve 2 credits for host tx control path"). To fix the issue, host driver only reserves tx control credit when there is a txctl frame is pending to send. And we also check available credit by using "not equal to 0" instead of "greater than 0" because tx_max and tx_seq are circled positive numbers.
