2025-11-10Documentation: taskstats: Reindent payload kinds listBagas Sanjaya
Payload kinds list text is indented at the first text column, rather than aligned to the list number. As an effect, the third item becomes sublist of second item's third sublist item (TASKTYPE_TYPE_STATS). Reindent the list text.

The WMI driver core only supports GUID strings containing only uppercase characters, however the GUID string used by the msi-wmi-platform driver contains a single lowercase character.

2025-11-07tcp: add net.ipv4.tcp_comp_sack_rtt_percentEric Dumazet
TCP SACK compression has been added in 2018 in commit 5d9f4262b7ea ("tcp: add SACK compression"). It is working great for WAN flows (with large RTT). Wifi in particular gets a significant boost _when_ ACK are suppressed. Add a new sysctl so that we can tune the very conservative 5 % value that has been used so far in this formula, so that small RTT flows can benefit from this feature. delay = min ( 5 % of RTT, 1 ms) This patch adds new tcp_comp_sack_rtt_percent sysctl to ease experiments and tuning. Given that we cap the delay to 1ms (tcp_comp_sack_delay_ns sysctl), set the default value to 33 %. Quoting Neal Cardwell ( https://lore.kernel.org/netdev/CADVnQymZ1tFnEA1Q=vtECs0=Db7zHQ8=+WCQtnhHFVbEOzjVnQ@mail.gmail.com/ ) The rationale for 33% is basically to try to facilitate pipelining, where there are always at least 3 ACKs and 3 GSO/TSO skbs per SRTT, so that the path can maintain a budget for 3 full-sized GSO/TSO skbs "in flight" at all times: + 1 skb in the qdisc waiting to be sent by the NIC next + 1 skb being sent by the NIC (being serialized by the NIC out onto the wire) + 1 skb being received and aggregated by the receiver machine's aggregation mechanism (some combination of LRO, GRO, and sack compression) Note that this is basically the same magic number (3) and the same rationales as: (a) tcp_tso_should_defer() ensuring that we defer sending data for no longer than cwnd/tcp_tso_win_divisor (where tcp_tso_win_divisor = 3), and (b) bbr_quantization_budget() ensuring that cwnd is at least 3 GSO/TSO skbs to maintain pipelining and full throughput at low RTTs Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Neal Cardwell <ncardwell@google.com> Link: https://patch.msgid.link/20251106115236.3450026-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

For example, sysfs for DBC ID 0 and accel minor number 0 looks like this, /sys/class/accel/accel0/dbc0_state Following are the states and their corresponding values, DBC_STATE_IDLE (0) DBC_STATE_ASSIGNED (1) DBC_STATE_BEFORE_SHUTDOWN (2) DBC_STATE_AFTER_SHUTDOWN (3) DBC_STATE_BEFORE_POWER_UP (4) DBC_STATE_AFTER_POWER_UP (5) Signed-off-by: Pranjal Ramajor Asha Kanojiya <quic_pkanojiy@quicinc.com> Signed-off-by: Youssef Samir <youssef.abdulrahman@oss.qualcomm.com> Signed-off-by: Zack McKevitt <zachary.mckevitt@oss.qualcomm.com> Reviewed-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Signed-off-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Link: https://patch.msgid.link/20251031174059.2814445-2-zachary.mckevitt@oss.qualcomm.com

Merge series from Alex Elder <elder@riscstar.com>: This series adds support for the SpacemiT K1 SoC QSPI. This IP is generally compatible with the Freescale QSPI driver, requiring three minor changes to enable it to be supported. The changes are: - Adding support for optional resets - Having the clock *not* be disabled when changing its rate - Allowing the size of storage blocks written to flash chips to be set to something different from the AHB buffer size
