2020-12-10iwlwifi: copy iwl_he_capa for modificationsJohannes Berg
This data is not necessarily the same across devices as we may modify it due to the number of antennas and for overrides (though in practice overrides are likely to be identical), so modifying the global data is wrong. Make a copy of it in the NVM data and modify it there instead.

2020-12-10iwlwifi: pcie: remove obsolete pre-release support codeEmmanuel Grumbach
We no longer need code that was introduced to differentiate between two early versions of 8260. We can remove this convoluted way to get the hardware version that was needed because of a bug in the register's configuration. Moreover, since we no longer need to access the PRPH registers, we no longer need to wake up the device, request ownership, etc... Remove all that. This allows us to get the rid of the obsolete comment about the AUX bus MISC address space which should have been moved when this code was moved away from here.

2020-12-09rtlwifi: rtl8192de: fix ofdm power compensationPing-Ke Shih
ofdm_index[] is used to indicate how many power compensation is needed to current thermal value. For internal PA module or 2.4G band, the min_index is different from other cases. This issue originally is reported by Dan. He found the size of ofdm_index[] is 2, but access index 'i' may be equal to 2 if 'rf' is 2 in case of 'is2t'. In fact, the chunk of code is added to wrong place, so move it back to proper place, and then power compensation and buffer overflow are fixed.

2020-12-08rtw88: reduce polling time of IQ calibrationChin-Yen Lee
When 8822CE is associating with AP, driver will poll status bit of IQ calibration to confirm the IQ calibration is done, and then move on the association process. Current polling time for IQ calibration is 6 seconds. But occasionally driver fails in polling the status bit because the status bit is not set after IQ calibration is done. When it happends, association process will be serieously delayed up to 6 seconds. To avoid it, we reduce polling time to 300ms, in which the IQ calibration can be done.

2020-12-07rtw88: declare hw supports ch 144Zong-Zhe Yang
When driver was developed, FCC regulation didn't enable channel 144 and there was no demand for channel 144 at that time. Although HW actually supports channel 144, driver didn't announce channel 144. Therefore, channel 144 (20 MHz), channel 142 (40 MHz) and channel 138 (80 MHz) couldn't be used. Today, channel 144 has been enabled by regulations and is gradually being supported. With test requirements, we declare hw supports channel 144.

There's no need to check min(budget, NUM_RX_DESC). At first budget (NAPI_POLL_WEIGHT = 64) is less then NUM_RX_DESC (256). And more important: Even in case of budget > NUM_RX_DESC we could safely continue processing descriptors as long as they are owned by the CPU. In addition replace rx_left with a normal counter variable, this allows to simplify the code. Last but not least there's no need any longer to pass the budget as an u32.

2020-12-04Merge branch 'perf-optimizations-for-tcp-recv-zerocopy'Jakub Kicinski
Arjun Roy says: ==================== Perf. optimizations for TCP Recv. Zerocopy This patchset contains several optimizations for TCP Recv. Zerocopy. Summarized: 1. It is possible that a read payload is not exactly page aligned - that there may exist "straggler" bytes that we cannot map into the caller's address space cleanly. For this, we allow the caller to provide as argument a "hybrid copy buffer", turning getsockopt(TCP_ZEROCOPY_RECEIVE) into a "hybrid" operation that allows the caller to avoid a subsequent recvmsg() call to read the stragglers. 2. Similarly, for "small" read payloads that are either below the size of a page, or small enough that remapping pages is not a performance win - we allow the user to short-circuit the remapping operations entirely and simply copy into the buffer provided. Some of the patches in the middle of this set are refactors to support this "short-circuiting" optimization. 3. We allow the user to provide a hint that performing a page zap operation (and the accompanying TLB shootdown) may not be necessary, for the provided region that the kernel will attempt to map pages into. This allows us to avoid this expensive operation while holding the socket lock, which provides a significant performance advantage. With all of these changes combined, "medium" sized receive traffic (multiple tens to few hundreds of KB) see significant efficiency gains when using TCP receive zerocopy instead of regular recvmsg(). For example, with RPC-style traffic with 32KB messages, there is a roughly 15% efficiency improvement when using zerocopy. Without these changes, there is a roughly 60-70% efficiency reduction with such messages when employing zerocopy. ==================== Link: https://lore.kernel.org/r/20201202225349.935284-1-arjunroy.kdev@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-12-04net-zerocopy: Defer vm zap unless actually needed.Arjun Roy
Zapping pages is required only if we are calling vm_insert_page into a region where pages had previously been mapped. Receive zerocopy allows reusing such regions, and hitherto called zap_page_range() before calling vm_insert_page() in that range. zap_page_range() can also be triggered from userspace with madvise(MADV_DONTNEED). If userspace is configured to call this before reusing a segment, or if there was nothing mapped at this virtual address to begin with, we can avoid calling zap_page_range() under the socket lock. That said, if userspace does not do that, then we are still responsible for calling zap_page_range(). This patch adds a flag that the user can use to hint to the kernel that a zap is not required. If the flag is not set, or if an older user application does not have a flags field at all, then the kernel calls zap_page_range as before. Also, if the flag is set but a zap is still required, the kernel performs that zap as necessary. Thus incorrectly indicating that a zap can be avoided does not change the correctness of operation. It also increases the batchsize for vm_insert_pages and prefetches the page struct for the batch since we're about to bump the refcount. An alternative mechanism could be to not have a flag, assume by default a zap is not needed, and fall back to zapping if needed. However, this would harm performance for older applications for which a zap is necessary, and thus we implement it with an explicit flag so newer applications can opt in. When using RPC-style traffic with medium sized (tens of KB) RPCs, this change yields an efficency improvement of about 30% for QPS/CPU usage.
