wifi: rtw89: pci: validate RX tag for RXQ and RPQ PCI RX ring is a kind of read/write index ring, and DMA and ring index are asynchronous, so suddenly driver gets newer index ahead before DMA. To resolve this rare situation, we use a RX tag as helpers to make sure DMA is done. The RX tag is a 13-bit value, and range is from 1 ~ 0x1FFF, but 0 isn't used so should be skipped. Only enable this validation to coming WiFi 7 chips, because existing chips use different design and don't really meet this situation. Add missed rx_ring_eq_is_full for 8851BE by the way.

rtw89: pci: add register definition to rtw89_pci_info to generalize pci code The PCI code of 8852AE and 8852CE are different, but the flow and register names are similar. To reuse the code, add a struct to define register or value accordingly. We also use chip id to control the slightly different flow.

rtw89: pci: support variant of fill_txaddr_info The txaddr_info is used to fill the DMA address of skb->data. The v1 version can support up to 10 entries, but the maximum size of each entry is 2047, so it fill more than one entry for large packet, like 3000 bytes.

rtw89: ser: control hci interrupts on/off by state While SER (system error recover) is processing, it's supposed to mean something is under recovery. So, disable interrupts (excluding the one of halt which could be used during SER) to avoid unexpected behavior. And then, enable interrupts after SER is done.

rtw89: pci: use a struct to describe all registers address related to DMA channel We have had a struct rtw89_pci_ch_dma_addr to describe register address, so use it as regular. Since the addresses should be changed dynamically according to operating mode, I don't change it to be constant. These changes don't affect the logic, so I put them in this separated patch.

rtw89: extract modules by chipset We are planning to support more chipsets, e.g. 8852C. Before that, we consider architecutre to handle multiple kinds of chipsets. Obviosuly, based on original design, rtw89_core module will have large size even if there is only one chipset under running. It is because all chipset related things are put in rtw89_core now. To reduce such overhead, we extract modules of rtw89 and adjust dependencies between modules. The following assumes that 8852AE, 8852AU, and 8852CE are all supported, we describe the difference before and after extraction. [Before extraction] ------------- |------------------------------------ | rtw89_usb | V ------------- --------------------------------------- ------------- | rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci | --------------------------------------- ------------- The data of 8852A and 8852C are built in rtw89_core. And rtw89_pci is the entry of 8852AE and 8852CE. And rtw89_usb is the entry of 8852AU. [After extraction] ------------- ---------------- |----------- | rtw89_usb | <-------- | rtw89_8852au | | ------------- ---------------- V --------------- | -------------- | | <--------------- | rtw89_core | <--- | rtw89_8852a | -------------- | | <--------------- ^ ^ --------------- | | | ------------- ---------------- | | | | <-------- | rtw89_8852ae | | |----------- | rtw89_pci | ---------------- | | | <----------------- | ------------- | | --------------- ---------------- |--------------- | rtw89_8852c | <------ | rtw89_8852ce | --------------- ---------------- The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c. And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus. Finally, 8852AE, 8852AU, and 8852CE have individual entry modules, i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.

rtw89: add Realtek 802.11ax driver This driver named rtw89, which is the next generation of rtw88, supports Realtek 8852AE 802.11ax 2x2 chip whose new features are OFDMA, DBCC, Spatial reuse, TWT and BSS coloring; now some of them aren't implemented though. The chip architecture is entirely different from the chips supported by rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges are totally redefined, so it's impossible to reuse register definition. To communicate with firmware, new H2C/C2H format is proposed. In order to have better utilization, TX DMA flow is changed to two stages DMA. To provide rich RX status information, additional RX PPDU packets are added. Since there are so many differences mentioned above, we decide to propose a new driver. It has many authors, they are listed in alphabetic order: Chin-Yen Lee <timlee@realtek.com> Ping-Ke Shih <pkshih@realtek.com> Po Hao Huang <phhuang@realtek.com> Tzu-En Huang <tehuang@realtek.com> Vincent Fann <vincent_fann@realtek.com> Yan-Hsuan Chuang <tony0620emma@gmail.com> Zong-Zhe Yang <kevin_yang@realtek.com> Tested-by: Aaron Ma <aaron.ma@canonical.com> Tested-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20211008035627.19463-1-pkshih@realtek.com
