In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine. Signed-off-by:

As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Signed-off-by:

This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by:

We're just trusting that these tables are of the right dimensions, when we could do better by just using the struct directly. Let's expose the struct txpwr_lmt_cfg_pair instead. The table changes were made by using some Vim macros, so that should help prevent any translation mistakes along the way. Remaining work: get the 'void *data' out of the generic struct rtw_table; all of these tables really deserve to be their own data structure, with proper type fields. Signed-off-by:

Firmware crash is a pretty rare event and can't happen too frequently as it has to be followed by a hardware reinitialization and config reload. It should be safe to don't use net_ratelimit() when it happens. For reporting & debugging purposes it's important to provide a complete log as the last lines are actually the most important. This change modifies brcmfmac to print all messages in an unlimited way in that specific case. With this change there should be finally a backtrace of firmware finally visible after a crash.

Arend van Spriel authored
When brcmf_detach() from the bus layer upon rmmod we can no longer communicate. Hence we will set the bus state to DOWN and cleanup the event and protocol layer. The network interfaces need to be deleted before brcmf_cfg80211_detach() because the latter does the wiphy_unregister() which issues a warning if there are still network devices linked to the wiphy instance.

The driver has custom regulatory rules which had maximum bandwidth for 5GHz channels set to 80MHz. As a consequence the driver can not use 160MHz in AP mode even when the device supports it. So relax the rules allowing 160MHz. After wiphy_register() the channel flags are updated according what the device actually supports. Reviewed-by:

The function chandef_to_chanspec() was not handling 160MHz bandwidth resulting in wrong encoding of the channel. That resulting in firmware rejecting the provided channel specification. Reviewed-by:

Testing with RTL8822BE hardware, when available memory is low, we frequently see a kernel panic and system freeze. First, rtw_pci_rx_isr encounters a memory allocation failure (trimmed): rx routine starvation WARNING: CPU: 7 PID: 9871 at drivers/net/wireless/realtek/rtw88/pci.c:822 rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] [ 2356.580313] RIP: 0010:rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] Then we see a variety of different error conditions and kernel panics, such as this one (trimmed): rtw_pci 0000:02:00.0: pci bus timeout, check dma status skbuff: skb_over_panic: text:00000000091b6e66 len:415 put:415 head:00000000d2880c6f data:000000007a02b1ea tail:0x1df end:0xc0 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:105! invalid opcode: 0000 [#1] SMP NOPTI RIP: 0010:skb_panic+0x43/0x45 When skb allocation fails and the "rx routine starvation" is hit, the function returns immediately without updating the RX ring. At this point, the RX ring may continue referencing an old skb which was already handed off to ieee80211_rx_irqsafe(). When it comes to be used again, bad things happen. This patch allocates a new, data-sized skb first in RX ISR. After copying the data in, we pass it to the upper layers. However, if skb allocation fails, we effectively drop the frame. In both cases, the original, full size ring skb is reused. In addition, to fixing the kernel crash, the RX routine should now generally behave better under low memory conditions.
