The series is based on the Lorenzo's patches: https://patchwork.kernel.org/project/linux-wireless/list/?series=95969 In the legacy tx arch, we move and store the whole skb content to the on-device memory when we send packets via high speed interface. (e.g. PCIe) However, MT7615 and the following generation use a new tx arch called “cut-through”, which only passes the physical address to the hardware, and the packet engine will fetch the packets before transmission. It saves on-chip memory for high throughput devices, and the token mechanism is used to manage the release of skb under this arch. And there might be other (existing or future) chips that use the same driver (e.g. mt7622/mt7663...), this is a starting point to unify MTK wireless chipsets. Detailed hardware information for this chip could be found on https://wikidevi.com/wiki/MediaTek_MT7615 Ryder Lee (4): mt76: add mac80211 driver for MT7615 PCIe-based chipsets mt76: add unlikely() for dma_mapping_error() check mt76: use macro for sn and seq_ctrl conversion MAINTAINERS : update entry for mt76 wireless driver MAINTAINERS | 2 + drivers/net/wireless/mediatek/mt76/Kconfig | 1 + drivers/net/wireless/mediatek/mt76/Makefile | 1 + drivers/net/wireless/mediatek/mt76/agg-rx.c | 2 +- drivers/net/wireless/mediatek/mt76/dma.c | 8 +- drivers/net/wireless/mediatek/mt76/mt7603/mac.c | 2 +- drivers/net/wireless/mediatek/mt76/mt7603/main.c | 2 +- drivers/net/wireless/mediatek/mt76/mt7615/Kconfig | 7 + drivers/net/wireless/mediatek/mt76/mt7615/Makefile | 5 + drivers/net/wireless/mediatek/mt76/mt7615/dma.c | 205 +++ drivers/net/wireless/mediatek/mt76/mt7615/eeprom.c | 98 ++ drivers/net/wireless/mediatek/mt76/mt7615/eeprom.h | 18 + drivers/net/wireless/mediatek/mt76/mt7615/init.c | 229 +++ drivers/net/wireless/mediatek/mt76/mt7615/mac.c | 775 +++++++++ drivers/net/wireless/mediatek/mt76/mt7615/mac.h | 300 ++++ drivers/net/wireless/mediatek/mt76/mt7615/main.c | 499 ++++++ drivers/net/wireless/mediatek/mt76/mt7615/mcu.c | 1656 ++++++++++++++++++++ drivers/net/wireless/mediatek/mt76/mt7615/mcu.h | 520 ++++++ drivers/net/wireless/mediatek/mt76/mt7615/mt7615.h | 195 +++ drivers/net/wireless/mediatek/mt76/mt7615/pci.c | 150 ++ drivers/net/wireless/mediatek/mt76/mt7615/regs.h | 203 +++ drivers/net/wireless/mediatek/mt76/mt76x02_util.c | 2 +- 22 files changed, 4872 insertions(+), 8 deletions(-) create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/Kconfig create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/Makefile create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/dma.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/eeprom.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/eeprom.h create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/init.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/mac.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/mac.h create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/main.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/mcu.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/mcu.h create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/mt7615.h create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/pci.c create mode 100644 drivers/net/wireless/mediatek/mt76/mt7615/regs.h -- 1.9.1
