Hi all, This series adds more USB4 v2 features. First it makes the bandwidth reservation to comply with the v2 connection manager guide, adds the PMPS packet support bit and enables asymmetric 120/40G switching to support the Ultra-High Bitrate DisplayPort modes. Applies on top of thunderbolt.git/next. Previous version of the series can be found through below link: https://lore.kernel.org/linux-usb/20231005092729.3595447-1-mika.westerberg@xxxxxxxxxxxxxxx/ Changes from v1: - Try to transition above links symmetric if a USB4 v2 router is connected whose link comes up as symmetric regardless whether it support asymmetric links or not (previously we just checked for the support). - Transition asymmetric also when DP tunnel is established if its consumption goes over the threshold. Gil Fine (5): thunderbolt: Make is_gen4_link() available to the rest of the driver thunderbolt: Change bandwidth reservations to comply USB4 v2 thunderbolt: Introduce tb_port_path_direction_downstream() thunderbolt: Add support for asymmetric link thunderbolt: Configure asymmetric link if needed and bandwidth allows Mika Westerberg (5): thunderbolt: Use constants for path weight and priority thunderbolt: Use weight constants in tb_usb3_consumed_bandwidth() thunderbolt: Set path power management packet support bit for USB4 v2 routers thunderbolt: Introduce tb_for_each_upstream_port_on_path() thunderbolt: Introduce tb_switch_depth() drivers/thunderbolt/path.c | 7 +- drivers/thunderbolt/switch.c | 328 +++++++++++++--- drivers/thunderbolt/tb.c | 689 ++++++++++++++++++++++++++++------ drivers/thunderbolt/tb.h | 58 ++- drivers/thunderbolt/tb_regs.h | 12 +- drivers/thunderbolt/tunnel.c | 161 ++++++-- drivers/thunderbolt/tunnel.h | 2 + drivers/thunderbolt/usb4.c | 106 ++++++ 8 files changed, 1149 insertions(+), 214 deletions(-) -- 2.40.1
