2017-08-30net: ti: cpsw-common: dont print error if ti_cm_get_macid() failsSekhar Nori1-1/+1
It is quite common for ti_cm_get_macid() to fail on some of the platforms it is invoked on. They include any platform where mac address is not part of SoC register space. On these platforms, mac address is read and populated in device-tree by bootloader. An example is TI DA850. Downgrade the severity of message to "information", so it does not spam logs when 'quiet' boot is desired. Signed-off-by: Sekhar Nori <[email protected]> Signed-off-by: David S.

2017-08-30iwlwifi: mvm: Avoid deferring non bufferable framesDavid Spinadel1-4/+5
Use bcast station for all non bufferable frames on AP and AD-HOC. The host is no longer aware of STAs PS status because of buffer station offload, so we can't rely on mac80211 to toggle on IEEE80211_TX_CTL_NO_PS_BUFFER bit. A possible issue with buffering such frames, beside the obvious spec violation, is when a station disconnects while in PS but the AP isn't aware of that. In such scenarios the AP won't be able to send probe responses or auth frames so the STA won't be able to reconnect and the AP will have a queue hang.

2017-08-29amd-xgbe: Interrupt summary bits are h/w version dependentTom Lendacky2-5/+16
There is a difference in the bit position of the normal interrupt summary enable (NIE) and abnormal interrupt summary enable (AIE) between revisions of the hardware. For older revisions the NIE and AIE bits are positions 16 and 15 respectively. For newer revisions the NIE and AIE bits are positions 15 and 14. The effect in changing the bit position is that newer hardware won't receive AIE interrupts in the current version of the driver. Specifically, the driver uses this interrupt to collect statistics on when a receive buffer unavailable event occurs and to restart the driver/device when a fatal bus error occurs. Update the driver to set the interrupt enable bit based on the reported version of the hardware. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2017-08-29smp: Avoid using two cache lines for struct call_single_dataYing Huang2-2/+2
struct call_single_data is used in IPIs to transfer information between CPUs. Its size is bigger than sizeof(unsigned long) and less than cache line size. Currently it is not allocated with any explicit alignment requirements. This makes it possible for allocated call_single_data to cross two cache lines, which results in double the number of the cache lines that need to be transferred among CPUs. This can be fixed by requiring call_single_data to be aligned with the size of call_single_data. Currently the size of call_single_data is the power of 2. If we add new fields to call_single_data, we may need to add padding to make sure the size of new definition is the power of 2 as well. Fortunately, this is enforced by GCC, which will report bad sizes. To set alignment requirements of call_single_data to the size of call_single_data, a struct definition and a typedef is used. To test the effect of the patch, I used the vm-scalability multiple thread swap test case (swap-w-seq-mt). The test will create multiple threads and each thread will eat memory until all RAM and part of swap is used, so that huge number of IPIs are triggered when unmapping memory. In the test, the throughput of memory writing improves ~5% compared with misaligned call_single_data, because of faster IPIs.

2017-08-28bnxt_en: Improve tx ring reservation logic.Michael Chan4-14/+44
When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again.
