TX FIFO size is 32k and it was divided into 256 pages with 128 bytes. A boundary is used to split pages into two parts, head part is used to store TX packets coming from host, and tail part is reserved for special purposes, such as beacon packet, null data packet and so on. The TX packets coming from host have many categories, such as VO, VI, BE, BK, MG and etc. When going into head part of TX FIFO, they are classified to four priority queue named low, normal, high and extra priority queues. Each priority queue occupies predefined number of page, if a certain priority queue is full, TX packet will store into PUB priority queue. Similarly, RX FIFO is 16k and split into two parts, head part is used to store RX packets, and tail part is 128 bytes and used to store report. Thus, we fill this boundary to register as well.

The txagc table is used to map rate_id and txagc register address and mask, and ops set_tx_power_index uses this table to write TX power to corresponding registers. Since 8723D is a 1x1 2.4G 11n chip, only CCK, OFDM and HT_MCS 0-7 are listed in the table. Signed-off-by:

The power polling command is one kind of power sequence commands. It's used to check hardware situation, and subsequent comamnds will be executed if hardware is ready. A special case is PCIE must toggle BIT_PFM_WOWL and try again if first try is failed. In order to reduce indentation to understand the code easier, move polling part to a separate function. Then, the 'while (1)...loop' is replaced by two statements to do first try and retry. Signed-off-by:

The mac power-on flow consists of three steps: 1. pre_sys_cfg (Before switching power state) 2. power_switch (Switching power state) 3. init_sys_cfg (Settings after swtiching power state) When switching power state, driver will load and parse the power sequence tables. For 8723D devices, the logics for parsing are most same except for the polling function. 8723D devices need to toggle BIT_PFM_WOWL twice. The settings after power state is switched for 8723D devices are quite different with other devices, extract a legacy function for them. For power-off flow, 8723D devices have the same logic with existing chips. But warning printed if we run power-off sequence in power-off state: rtw_pci 0000:03:00.0: failed to poll offset=0x5f8 mask=0xff value=0x0 The scenario is user do 'ifconfig up' that will run power-on sequence to bring up and then run power-off sequence to enter idle (IEEE80211_CONF_IDLE). Then, user do 'ifconfig down' that will run power-off sequence again, and the warning is shown. Original code check power-on state to avoid to run power-on sequence twice, and this commit extends to check both power-on and power-off states. Signed-off-by:

The firmware of 11AC devices need more information to support more offload functions, such as IQK. And 11N devices such as 8723D does not support offload these function in firmware, there is no need to send these additional information to firmware when it comes to 11N devices. Signed-off-by:

The WLAN CPU of 8723D device is different from others, add legacy firmware download function for it. A new variable wlan_cpu is used to decide which firmware download function we should use. Legacy firmware file contains 32 bytes header including version and subversion. When downloading to wlan cpu, header is excluded. Firmware is downloaded via beacon queue to reserved page that is a part of TX buffer. Since 11N WLAN CPU uses different control registers, this patch introduces related control registers.

8723D use SIPI to indirectly read RF register instead of directly read, so introduce a new struct rtw_rf_sipi_addr and new function rtw_phy_read_rf_sipi(). Since other chips don't use the new function, only 8723D needs to fill struct rtw_rf_sipi_addr in rtw_chip_info. Because there are two kinds of functions for reading RF registers now, change rtw_phy_read_rf() to chip->ops->read_rf() in rtw_phy_write_rf_reg_sipi() so that we can switch tp proper RF read functions depends on the type of the chip. Though 8723D is an 1x1 chip, it has two RF PHY and we can switch to one of them, and that should be configured properly. Hence, add a fix_rf_phy_num to struct rtw_chip_info to allow driver to set one of the PHY's registers for 8723D, even it is only 1x1. Another variable rf_phy_num is introduced to keep the constraint number of RF path we can access, and its value is: rf_phy_num = (fix_rf_phy_num ? fix_rf_phy_num : rf_path_num) Signed-off-by:

8723D doesn't support beamform because rtw88 only supports VHT beamform but 8723d doesn't have VHT capability. Though 8723d doesn't support beamform, BSS_CHANGED_MU_GROUPS is still marked as changed when doing disassociation. So, add wrapper functions for all beamform ops to make sure they aren't NULL before calling. Signed-off-by:

To support ieee80211_ops::set_antenna, the driver can decide if the antenna mask is accepted, otherwise it can return an error code. Because each chip could have different limitations, let the chip check the mask and return. Also the antenna mask for TRX from upper space is 32-bit long. Change the antenna mask for rtw_chip_ops::set_antenna from u8 to u32. Signed-off-by:

This patch fixes commit 75388acd ("add mac80211-based driver for legacy BCM43xx devices") In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in b43legacy is reported. Upon testing, thus problem exists on PPC and X86 platforms, is present in the oldest kernel tested (3.2), and has been present in the driver since it was first added to the kernel. The problem is a corrupted channel status received from the device. Both the internal card in a PowerBook G4 and the PCMCIA version (Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2 (revision 4 of the 802.11 core) of the chip has been tested. No other devices using b43legacy are available for testing. Various sources of the problem were considered. Buffer overrun and other sources of corruption within the driver were rejected because the faulty channel status is always the same, not a random value. It was concluded that the faulty data is coming from the device, probably due to a firmware bug. As that source is not available, the driver must take appropriate action to recover. At present, the driver reports the error, and them continues to process the bad packet. This is believed that to be a mistake, and the correct action is to drop the correpted packet.
