T6 introduced a Timer Mechanism in SGE called the SGE Doorbell Queue Timer. With this we can now configure TX Queues to get CIDX Updates when: Time(CIDX == PIDX) >= Timer Previously we rely on TX Queue Status Page updates by hardware for DMA completions. This will make Hardware/Firmware actually deliver the CIDX Updates as Ingress Queue messages with commensurate Interrupts. So we now have a new RX Path component for processing CIDX Updates and reclaiming TX Descriptors faster.

Deepa Dinamani says: ==================== uapi: Add a new header for time types The series aims at adding a new time header: time_types.h. This header is what will eventually hold all the uapi time types that we plan to leave across the interfaces after the y2038 cleanup. The series was discussed with Arnd Bergmann. The second patch fixes the errqueue.h header, which has a dependency on these types. Note that there may be a trivial merge conflict with linux-next c70a772f ("y2038: remove struct definition redirects"). ==================== Signed-off-by:

sys/time.h is the mandated include for many time related defines. However, linux/time.h overlaps sys/time.h significantly and this makes including both from userspace or one from the other impossible. This also means that userspace can get away with including sys/time.h whenever it needs linux/time.h and this is what's been happening in the user world usually. But, we have new data types that we plan to use in the uapi time interfaces also defined in the linux/time.h. But, we are unable to use these types when sys/time.h is included. Hence, move the new types to a new header, time_types.h. We intend to eventually have all the uapi defines that the kernel uses defined in this header. Note that the plan is to replace uapi interfaces with timeval to use __kernel_old_timeval, timespec to use __kernel_old_timespec etc. Reported-by:

While finding the devlink device during region reading, devlink device list is accessed and devlink device is returned without holding a lock. This could lead to use-after-free accesses. While at it, add lockdep assert to ensure that all future callers hold the lock when calling devlink_get_from_attrs().

This patch is a little improvement. If user use the command shown as below, we should print the info [1] instead of [2]. The eth0 exists actually, and it may confuse user. $ echo "eth0" > /sys/class/net/bond4/bonding/slaves [1] "bond4: no command found in slaves file - use +ifname or -ifname" [2] "write error: No such device" Signed-off-by:

Ido Schimmel says: ==================== mlxsw: hwmon and thermal extensions Vadim says: This patchset contains various improvements to hwmon and thermal code in mlxsw. The most significant improvement is the ability to read modules' temperature attributes (input, fault, critical and emergency thresholds) as well as fans' fault indication. These new attributes will improve the ability to monitor the system. Patches #1-#4 add the necessary device registers and APIs to read modules' temperature attributes and fans' fault indication. Patches #5-#8 perform small improvements in hwmon and thermal code such as using a more indicative name for cooling devices. Patch #9 exposes fans' fault indication via hwmon. Patch #10 exposes modules' temperature attributes via hwmon. Patch #11 adds an hwmon label to modules' temperature sensor. This helps to parse the output of utilities such as "sensors". Patch #12 allows to bind an external cooling device ("mlxreg-fan") to mlxsw thermal zone. This will allow the mlxsw thermal zone to change the cooling level of cooling devices not programmed via switch registers. ==================== Signed-off-by: -

Add label attribute to hwmon object for exposing QSFP module's temperature sensor name. Modules are labeled as "front panel xxx". The label is used by utilities such as "sensors": front panel 001: +0.0C (crit = +0.0C, emerg = +0.0C) .. front panel 020: +31.0C (crit = +70.0C, emerg = +80.0C) .. front panel 056: +41.0C (crit = +70.0C, emerg = +80.0C) Signed-off-by:

Modify thermal zone trip points setting for better alignment with system thermal requirement. Add hysteresis thresholds for thermal trips in order to avoid throttling around thermal trip point.

Add low frequency bus capability in order to allow core functionality separation based on bus type. Driver could run over PCIe, which is considered as high frequency bus or I2C, which is considered as low frequency bus. In the last case time setting, for example, for thermal polling interval, should be increased. Use different thermal monitoring based on bus type. For I2C bus time is set to 20 seconds, while for PCIe 1 second polling interval is used. Signed-off-by:

We need to set the error message on this path otherwise some of the callers, such as test_hints_case(), print from an uninitialized pointer. We had a similar bug earlier and set "errmsg" to NULL in the caller, test_delta_action_item(). That code is no longer required so I have removed it.

Jesper Dangaard Brouer says: ==================== Fix page_pool API and dma address storage As pointed out by David Miller in [1] the current page_pool implementation stores dma_addr_t in page->private. This won't work on 32-bit platforms with 64-bit DMA addresses since the page->private is an unsigned long and the dma_addr_t a u64. Since no driver is yet using the DMA mapping capabilities of the API let's fix this by storing the information in 'struct page' and use that to store and retrieve DMA addresses from network drivers. As long as the addresses returned from dma_map_page() are aligned the first bit, used by the compound pages code should not be set. Ilias tested the first two patches on Espressobin driver mvneta, for which we have patches for using the DMA API of page_pool.
