Hi all, This series implements an optional feature in USB4 spec called DisplayPort bandwidth allocation mode. This allows the graphics driver to negotiate with the Thunderbolt driver the bandwidth requirements dynamically through DP IN adapters of the host router (graphics driver uses DP AUX registers for this). This enables more "fine grained" bandwidth allocation. Mika Westerberg (8): thunderbolt: Use decimal port number in control and tunnel logs too thunderbolt: Log DP adapter type thunderbolt: Improve debug logging in tb_available_bandwidth() thunderbolt: Take CL states into account when waiting for link to come up thunderbolt: Increase timeout of DP OUT adapter handshake thunderbolt: Add functions to support DisplayPort bandwidth allocation mode thunderbolt: Include the additional DP IN double word in debugfs dump thunderbolt: Add support for DisplayPort bandwidth allocation mode drivers/thunderbolt/ctl.c | 52 +++- drivers/thunderbolt/ctl.h | 2 + drivers/thunderbolt/debugfs.c | 5 +- drivers/thunderbolt/switch.c | 42 ++- drivers/thunderbolt/tb.c | 504 ++++++++++++++++++++++++++++-- drivers/thunderbolt/tb.h | 37 +++ drivers/thunderbolt/tb_msgs.h | 11 +- drivers/thunderbolt/tb_regs.h | 36 +++ drivers/thunderbolt/tunnel.c | 496 ++++++++++++++++++++++++++--- drivers/thunderbolt/tunnel.h | 18 ++ drivers/thunderbolt/usb4.c | 571 ++++++++++++++++++++++++++++++++++ 11 files changed, 1689 insertions(+), 85 deletions(-) -- 2.35.1
