From: Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx> This is a new mac80211 driver for Realtek 802.11ac wireless network chips. rtw88 supports 8822BE and 8822CE chips, and will be able to support multi-vif combinations in run-time. For now, only PCI bus is supported, but rtw88 was originally designed to optionally support three buses includes USB & SDIO. USB & SDIO modules will soon be supported by rtw88, with configurable core module to fit with different bus modules in the same time. For example, if we choose 8822BE and 8822CU, only PCI & USB modules will be selected, built, loaded into kernel. This is one of the major difference from rtlwifi, which can only support specific combinations. Another difference from rtlwifi is that rtw88 is designed to support the latest Realtek 802.11ac wireless network chips like 8822B and 8822C series. Compared to the earlier chips supported by rtlwifi like the 802.11n 8192EE chipset or 802.11ac 8821AE/8812AE chips, newer ICs have different MAC & PHY settings, such as new multi-port feature for the MAC layer design and Jaguar2/Jaguar3 PHY layer IPs. Multi-Port feature is also supported under rtw88's software architecture. rtlwifi can only support one vif in the same time, most because of the hardware limitations for early chips, hence the original design of it also restricts the usage of multi-vif support, so latest chipset seems not take advantages from its new MAC engine. However, rtw88 can run multiple vifs concurrently by holding them on hardware ports provided by MAC engine, hence can easily start different roles on a single device. Based on the reasons mentioned before, we implemented rtw88. It had many authors, they are listed here alphabetically: Ping-Ke Shih <pkshih@xxxxxxxxxxx> Tzu-En Huang <tehuang@xxxxxxxxxxx> Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx> v2 - add comment for watch dog v3 - change tree location to wireless-next v4 - remove useless "T:" and "W:" lines in MAINTAINERS file, as we don't have our own tree and wiki page now - rename patch 13 to "add MAINTAINERS entry" - use skb_pull to remove tx descriptors before reporting tx status to mac80211 stack, otherwise mac80211 tx status will always fail to match addr1/addr2 and will finally trigger to disconnect - return back to operating channel when we leave IDLE state, as mac80211 stack expected. If we don't, mac80211 will assume we are already at channel 1 and start to scan. And we will never be able to connect to APs that are in channel 1. (which is most AP's default channel) - wait for async firmware load successfully, otherwise some slower platform might start to download firmware before loaded. And system crashes with a null pointer accessed. - fix typo for mac.h __RTW_MAc_H__ -> __RTW_MAC_H__ v5 - add rtw_debug_mask for rtw_dbg to control debug messages - use dev_printk for rtw_dbg to not depend on CONFIG_DYNAMIC_DEBUG - remove useless rtw_pci_parse_configuration - keep struct and MODULE_* declaration close - use macro instead of ugly struct layout with #ifdef __LITTLE_ENDIAN - simplify efuse logical map parsing function - remove unused member and whole map dump for efuse - reduce some usage of magic number - enable DMA sync to avoid pci bus timeout Yan-Hsuan Chuang (13): rtw88: main files rtw88: core files rtw88: hci files rtw88: trx files rtw88: mac files rtw88: fw and efuse files rtw88: phy files rtw88: debug files rtw88: chip files rtw88: 8822B init table rtw88: 8822C init table rtw88: Kconfig & Makefile rtw88: add MAINTAINERS entry MAINTAINERS | 6 + drivers/net/wireless/realtek/Kconfig | 1 + drivers/net/wireless/realtek/Makefile | 1 + drivers/net/wireless/realtek/rtw88/Kconfig | 55 + drivers/net/wireless/realtek/rtw88/Makefile | 19 + drivers/net/wireless/realtek/rtw88/debug.c | 637 + drivers/net/wireless/realtek/rtw88/debug.h | 52 + drivers/net/wireless/realtek/rtw88/efuse.c | 160 + drivers/net/wireless/realtek/rtw88/efuse.h | 26 + drivers/net/wireless/realtek/rtw88/fw.c | 616 + drivers/net/wireless/realtek/rtw88/fw.h | 206 + drivers/net/wireless/realtek/rtw88/hci.h | 211 + drivers/net/wireless/realtek/rtw88/mac.c | 1016 + drivers/net/wireless/realtek/rtw88/mac.h | 35 + drivers/net/wireless/realtek/rtw88/mac80211.c | 482 + drivers/net/wireless/realtek/rtw88/main.c | 1198 ++ drivers/net/wireless/realtek/rtw88/main.h | 1118 + drivers/net/wireless/realtek/rtw88/pci.c | 1198 ++ drivers/net/wireless/realtek/rtw88/pci.h | 236 + drivers/net/wireless/realtek/rtw88/phy.c | 1670 ++ drivers/net/wireless/realtek/rtw88/phy.h | 125 + drivers/net/wireless/realtek/rtw88/ps.c | 166 + drivers/net/wireless/realtek/rtw88/ps.h | 20 + drivers/net/wireless/realtek/rtw88/reg.h | 412 + drivers/net/wireless/realtek/rtw88/regd.c | 391 + drivers/net/wireless/realtek/rtw88/regd.h | 67 + drivers/net/wireless/realtek/rtw88/rtw8822b.c | 1591 ++ drivers/net/wireless/realtek/rtw88/rtw8822b.h | 155 + .../net/wireless/realtek/rtw88/rtw8822b_table.c | 20783 +++++++++++++++++++ .../net/wireless/realtek/rtw88/rtw8822b_table.h | 18 + drivers/net/wireless/realtek/rtw88/rtw8822c.c | 1169 ++ drivers/net/wireless/realtek/rtw88/rtw8822c.h | 171 + .../net/wireless/realtek/rtw88/rtw8822c_table.c | 4150 ++++ .../net/wireless/realtek/rtw88/rtw8822c_table.h | 16 + drivers/net/wireless/realtek/rtw88/rx.c | 151 + drivers/net/wireless/realtek/rtw88/rx.h | 41 + drivers/net/wireless/realtek/rtw88/sec.c | 120 + drivers/net/wireless/realtek/rtw88/sec.h | 39 + drivers/net/wireless/realtek/rtw88/tx.c | 273 + drivers/net/wireless/realtek/rtw88/tx.h | 81 + 40 files changed, 38882 insertions(+) create mode 100644 drivers/net/wireless/realtek/rtw88/Kconfig create mode 100644 drivers/net/wireless/realtek/rtw88/Makefile create mode 100644 drivers/net/wireless/realtek/rtw88/debug.c create mode 100644 drivers/net/wireless/realtek/rtw88/debug.h create mode 100644 drivers/net/wireless/realtek/rtw88/efuse.c create mode 100644 drivers/net/wireless/realtek/rtw88/efuse.h create mode 100644 drivers/net/wireless/realtek/rtw88/fw.c create mode 100644 drivers/net/wireless/realtek/rtw88/fw.h create mode 100644 drivers/net/wireless/realtek/rtw88/hci.h create mode 100644 drivers/net/wireless/realtek/rtw88/mac.c create mode 100644 drivers/net/wireless/realtek/rtw88/mac.h create mode 100644 drivers/net/wireless/realtek/rtw88/mac80211.c create mode 100644 drivers/net/wireless/realtek/rtw88/main.c create mode 100644 drivers/net/wireless/realtek/rtw88/main.h create mode 100644 drivers/net/wireless/realtek/rtw88/pci.c create mode 100644 drivers/net/wireless/realtek/rtw88/pci.h create mode 100644 drivers/net/wireless/realtek/rtw88/phy.c create mode 100644 drivers/net/wireless/realtek/rtw88/phy.h create mode 100644 drivers/net/wireless/realtek/rtw88/ps.c create mode 100644 drivers/net/wireless/realtek/rtw88/ps.h create mode 100644 drivers/net/wireless/realtek/rtw88/reg.h create mode 100644 drivers/net/wireless/realtek/rtw88/regd.c create mode 100644 drivers/net/wireless/realtek/rtw88/regd.h create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822b.c create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822b.h create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822b_table.c create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822b_table.h create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822c.c create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822c.h create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822c_table.c create mode 100644 drivers/net/wireless/realtek/rtw88/rtw8822c_table.h create mode 100644 drivers/net/wireless/realtek/rtw88/rx.c create mode 100644 drivers/net/wireless/realtek/rtw88/rx.h create mode 100644 drivers/net/wireless/realtek/rtw88/sec.c create mode 100644 drivers/net/wireless/realtek/rtw88/sec.h create mode 100644 drivers/net/wireless/realtek/rtw88/tx.c create mode 100644 drivers/net/wireless/realtek/rtw88/tx.h -- 2.7.4
