2023-08-07net: stmmac: dwmac-imx: enable MAC propagation delay correction for i.MX8MPJohannes Zink1-0/+5
As the i.MX8MP supports reading MAC propagation delay and correcting the Hardware timestamp counter for additional delays [1], enable the feature for this SoC. This reduces phase error of the PPS output from the PTP Hardware Clock from approx 150ns to 100ns. [1] i.MX8MP Reference Manual, rev.1 Section 11.7.2.5.3 "Timestamp correction" Signed-off-by: Johannes Zink <j.zink@pengutronix.de> Link: https://lore.kernel.org/r/20230719-stmmac_correct_mac_delay-v3-2-61e63427735e@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-08-07net: stmmac: correct MAC propagation delayJohannes Zink4-0/+58
The IEEE1588 Standard specifies that the timestamps of Packets must be captured when the PTP message timestamp point (leading edge of first octet after the start of frame delimiter) crosses the boundary between the node and the network. As the MAC latches the timestamp at an internal point, the captured timestamp must be corrected for the additional data transmission latency, as described in the publicly available datasheet [1]. This patch only corrects for the MAC-Internal delay, which can be read out from the MAC_Ingress_Timestamp_Latency register on DWMAC version 5, since the Phy framework currently does not support querying the Phy ingress and egress latency. The Closs Domain Crossing Circuits errors as indicated in [1] are already being accounted in the stmmac_get_tx_hwtstamp() function and are not corrected here. As the Latency varies for different link speeds and MII modes of operation, the correction value needs to be updated on each link state change. As the delay also causes a phase shift in the timestamp counter compared to the rest of the network, this correction will also reduce phase error when generating PPS outputs from the timestamp counter. Since the correction registers may be unavailable on some hardware and no feature bits are documented for dynamically detection of the MAC propagation delay readout, introduce a feature bit to explicitely enable MAC delay Correction in the gluecode driver.

2023-08-06gve: RX path for DQO-QPLRushil Gupta2-18/+114
The RX path allocates the QPL page pool at queue creation, and tries to reuse these pages through page recycling. This patch ensures that on refill no non-QPL pages are posted to the device. When the driver is running low on free buffers, an ondemand allocation step kicks in that allocates a non-qpl page for SKB business to free up the QPL page in use. gve_try_recycle_buf was moved to gve_rx_append_frags so that driver does not attempt to mark buffer as used if a non-qpl page was allocated ondemand.

Each QPL page is divided into GVE_TX_BUFS_PER_PAGE_DQO buffers. When a packet needs to be transmitted, we break the packet into max GVE_TX_BUF_SIZE_DQO sized chunks and transmit each chunk using a TX descriptor. We allocate the TX buffers from the free list in dqo_tx. We store these TX buffer indices in an array in the pending_packet structure. The TX buffers are returned to the free list in dqo_compl after receiving packet completion or when removing packets from miss completions list.

struct netdev_rx_queue is touched in only a few places and having it defined in netdevice.h brings in the dependency on xdp.h, because struct xdp_rxq_info gets embedded in struct netdev_rx_queue. In prep for removal of xdp.h from netdevice.h move all the netdev_rx_queue stuff to a new header. We could technically break the new header up to avoid the sysfs.h include but it's so rarely included it doesn't seem to be worth it at this point.

2023-08-03wifi: rtw89: return failure if needed firmware elements are not recognizedPing-Ke Shih7-0/+18
WiFi 7 chips doesn't have static const tables defined in driver. If tables aren't loaded properly from firmware file, driver can get NULL pointer access exception. One way is to add the checking statements when trying to access these tables, but I choose to check them right after loading firmware elements from firmware file, so I don't need to add error handlers everywhere. Currently, the needed firmware elements of WiFi 6 chips are all zero, and coming WiFi 7 chip will need at least BB MCU, parameters of BB and RF. We will add them after 8922AE is verified.

2023-08-03wifi: rtw89: introduce infrastructure of firmware elementsPing-Ke Shih3-0/+135
In order to pack more data into firmware file, we introduce firmware elements and append BB_MCU firmware first. The first part of new firmware file is still unchanged firmware of WiFi CPU, so the new firmware format can be backward compatible to old format. The new elements part consists of ID and size basically, which can append more elements simply. To avoid unaligned access in certain platform and be easy to read, headers of all elements start at 16-byte aligned address. +===========================================+ | original firmware | | +-------------+ | | padding | +===========================================+ | elm ID 1 | elm size | other header data | +----------+----------+ | | | +-------------------------------------------+ | content (variable length) | | +-------------+ | | padding | +===========================================+ | elm ID 2 | elm size | other header data | +----------+----------+ | | | +-------------------------------------------+ | content (variable length) | | +-----------------------+ | | (no padding for the last one) +===================+ More detail of element header is shown below. The additional fields 'version' and 'element_priv[]' are meta data of elements, so that we can know element version easily, and element_priv[] provide specific fields for certain element, such as RF path index for RF parameter tables. +===========================================+ | elm ID | elm size | version | rsvd0 | +----------+----------+----------+----------+ | rsvd1/2 | element_priv[] | +-------------------------------------------+ Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230801021127.15919-7-pkshih@realtek.com

A firmware with v1 format contains many sections to download. Add parser to read section type, target address, length, checksum and so on, and then download the section to WiFi CPU with proper location. The additional dynamic header length named dynamic_hdr_len is used to skip content of dynamic header containing compiler flags of firmware, which can help to determine variant firmware build, but currently rtw89 only use single one variant. So, just skip the content. The layout of a WiFi CPU firmware with v1 format looks like: +---------------------------------------+ | Header (12 words) | +---------------------------------------+ | Section header 1 (4 words) | | Section header 2 (4 words) | | Section header 3 (4 words) | | ... | +---------------------------------------+ | Dynamic header (variable length) | +---------------------------------------+ | Data used & pointed by section | | ... | +---------------------------------------+ Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230801021127.15919-5-pkshih@realtek.com

Deadlock is easily happened while shutdown wlan interface such as run "ifconfig wlan0 down". The reason is because when ar->regd_update_work is ran, it will call wiphy_lock(ar->hw->wiphy) in function ath12k_regd_update() which is running in workqueue of ieee80211_local queued by ieee80211_queue_work(). Another thread from "ifconfig wlan0 down" will also accuqire the lock by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and then it call ieee80211_stop_device() to flush_workqueue(local->workqueue), this will wait the workqueue of ieee80211_local finished. Then deadlock will happen easily if the two thread run meanwhile.

2023-08-03wifi: ath12k: add handler for scan event WMI_SCAN_EVENT_DEQUEUEDWen Gong1-0/+2
When wlan interface is up, and 11d scan is sent to the firmware, then firmware needs to spend couple of seconds to complete the 11d scan. If normal scan from user space arrives to ath12k at this moment, then the normal scan request is also sent to the firmware, but the scan started event will be reported to ath12k until the 11d scan complete. When timed out for the scan started in ath12k, ath12k stops the normal scan and the firmware reports WMI_SCAN_EVENT_DEQUEUED to ath12k for the normal scan. ath12k has no handler for the event and then timed out for the scan completed in ath12k_scan_stop(), and ath12k prints the following error message.
