qca_spi: Make interrupt remembering atomic

2024-06-27T11:52:21Z

[ Upstream commit 2d7198278ece01818cd95a3beffbdf8b2a353fa0 ] The whole mechanism to remember occurred SPI interrupts is not atomic, which could lead to unexpected behavior. So fix this by using atomic bit operations instead.

rtnetlink: prepare nla_put_iflink() to run under RCU

2024-02-26T11:46:12Z

We want to be able to run rtnl_fill_ifinfo() under RCU protection instead of RTNL in the future. This patch prepares dev_get_iflink() and nla_put_iflink() to run either with RTNL or RCU held. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

qca_spi: Improve calculation of RX buffer size

2024-01-31T13:38:50Z

There are two points with the calculation of RX buffer size which are not optimal: 1. dev->mtu is a mutual parameter and it's currently initialized with QCAFRM_MAX_MTU. But for RX buffer size calculation we always need the maximum possible MTU. So better use the define directly. 2. This magic number 4 represent the hardware generated frame length which is specific to SPI. We better replace this with the suitable define. There is no functional change.

qca_spi: Introduce QCASPI_RX_MAX_FRAMES

2024-01-31T13:38:50Z

Currently qca_spi reserves enough space for 4 complete Ethernet over SPI frames in the receive buffer. Unfortunately this is hidden under a magic number. So replace it with a more self explaining define. Signed-off-by: Stefan Wahren Reviewed-by: Jacob Keller Signed-off-by: David S. Miller

qca_spi: Add QCASPI prefix to ring defines

All defines in qca_spi.h except of the two ring limit defines have a QCASPI prefix. Since the name is quite generic add the QCASPI prefix to avoid possible name conflicts. Signed-off-by: Stefan Wahren Reviewed-by: Jacob Keller Signed-off-by: David S. Miller
