2021-02-12mmc: mmc_test: use erase_arg for mmc_erase commandYann Gautier
Since [1], the erase argument for mmc_erase() function is saved in erase_arg field of card structure. It is preferable to use it instead of hard-coded MMC_SECURE_ERASE_ARG, which from eMMC 4.51 spec is not recommended: "6.6.16 Secure Erase NOTE Secure Erase is included for backwards compatibility. New system level implementations (based on v4.51 devices and beyond) should use Erase combined with Sanitize instead of secure erase." On STM32MP157C-EV1 board, embedding a THGBMDG5D1LBAIL eMMC, using MMC_ERASE command with MMC_SECURE_ERASE_ARG may stuck the STM32 SDMMC IP, if test 37 or test 38 are launched just after a write test, e.g. test 36. Using the default MMC_ERASE argument from framework with erase_arg, which default in our case to MMC_DISCARD_ARG does no more trig the issue.

2021-02-12iommu/amd: Fix performance counter initializationSuravee Suthikulpanit
Certain AMD platforms enable power gating feature for IOMMU PMC, which prevents the IOMMU driver from updating the counter while trying to validate the PMC functionality in the init_iommu_perf_ctr(). This results in disabling PMC support and the following error message: "AMD-Vi: Unable to read/write to IOMMU perf counter" To workaround this issue, disable power gating temporarily by programming the counter source to non-zero value while validating the counter, and restore the prior state afterward.

2021-02-12mac80211: minstrel_ht: significantly redesign the rate probing strategyFelix Fietkau
The biggest flaw in current minstrel_ht is the fact that it needs way too many probing packets to be able to quickly find the best rate. Depending on the wifi hardware and operating mode, this can significantly reduce throughput when not operating at the highest available data rate. In order to be able to significantly reduce the amount of rate sampling, we need a much smarter selection of probing rates. The new approach introduced by this patch maintains a limited set of available rates to be tested during a statistics window. They are split into distinct categories: - MINSTREL_SAMPLE_TYPE_INC - incremental rate upgrade: Pick the next rate group and find the first rate that is faster than the current max. throughput rate - MINSTREL_SAMPLE_TYPE_JUMP - random testing of higher rates: Pick a random rate from the next group that is faster than the current max throughput rate. This allows faster adaptation when the link changes significantly - MINSTREL_SAMPLE_TYPE_SLOW - test a rate between max_prob, max_tp2 and max_tp in order to reduce the gap between them In order to prioritize sampling, every 6 attempts are split into 3x INC, 2x JUMP, 1x SLOW. Available rates are checked and refilled on every stats window update. With this approach, we finally get a very small delta in throughput when comparing setting the optimal data rate as a fixed rate vs normal rate control operation.

2021-02-12mac80211: minstrel_ht: reduce the need to sample slower ratesFelix Fietkau
In order to more gracefully be able to fall back to lower rates without too much throughput fluctuations, initialize all untested rates below tested ones to the maximum probabilty of higher rates. Usually this leads to untested lower rates getting initialized with a probability value of 100%, making them better candidates for fallback without having to rely on random probing Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20210127055735.78599-3-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2021-02-12cfg80211: initialize reg_rule in __freq_reg_info()Luca Coelho
Sparse started warning on this function because we can potentially return an uninitialized value. The reason is that if the caller passes a min_bw value that is higher then the last value in bws[], we will not go into the loop and reg_rule will remain initialized. This cannot happen because the only caller of this function uses either 1 or 20 in min_bw, but the function will be more robust if we pre-initialize the value.

2021-02-12mac80211: enable QoS support for nl80211 ctrl portMarkus Theil
This patch unifies sending control port frames over nl80211 and AF_PACKET sockets a little more. Before this patch, EAPOL frames got QoS prioritization only when using AF_PACKET sockets. __ieee80211_select_queue only selects a QoS-enabled queue for control port frames, when the control port protocol is set correctly on the skb. For the AF_PACKET path this works, but the nl80211 path used ETH_P_802_3. Another check for injected frames in wme.c then prevented the QoS TID to be copied in the frame. In order to fix this, get rid of the frame injection marking for nl80211 ctrl port and set the correct ethernet protocol. Please note: An erlier version of this path tried to prevent frame aggregation for control port frames in order to speed up the initial connection setup a little. This seemed to cause issues on my older Intel dvm-based hardware, and was therefore removed again. Future commits which try to reintroduce this have to check carefully how hw behaves with aggregated and non-aggregated traffic for the same TID.

2021-02-12rtw88: add napi supportPo-Hao Huang
Use napi to reduce overhead on rx interrupts. Driver used to interrupt kernel for every Rx packet, this could affect both system and network performance. NAPI is a mechanism that uses polling when processing huge amount of traffic, by doing this the number of interrupts can be decreased. Network performance can also benefit from this patch. Since TCP connection is bidirectional and acks are required for every several packets. These ack packets occupie the PCI bus bandwidth and could lead to performance degradation. When napi is used, GRO receive is enabled by default in the mac80211 stack. So mac80211 won't pass every RX TCP packets to the kernel TCP network stack immediately. Instead an aggregated large length TCP packet will be delivered. This reduces the tx acks sent and gains rx performance. After the patch, the Rx throughput increases about 25Mbps in 11ac.

Their encoding, however, uses dst_reg field as a base register, which causes opt_subreg_zext_lo32_rnd_hi32() to zero-extend said base register instead of the one the insn really defines (r0 or src_reg).

Based on [1], BPF_CMPXCHG should always load the old value into R0. The phrasing in bpf.rst is somewhat ambiguous in this regard, improve it to make this aspect crystal clear.

Tariq Toukan says: ==================== Compile-flag for sock RX queue mapping Socket's RX queue mapping logic is useful also for non-XPS use cases. This series breaks the dependency between the two, introducing a new kernel config flag SOCK_RX_QUEUE_MAPPING. Here we select this new kernel flag from TLS_DEVICE, as well as XPS. ==================== Acked-by: Jakub Kicinski <kuba@kernel.org>
