2023-08-25hwmon: (sis5595) Do PCI error checks on own lineIlpo Järvinen
Instead of if conditions with line splits, use the usual error handling pattern with a separate variable to improve readability.

2023-08-25PCI/AER: Simplify AER_RECOVER_RING_SIZE definitionBjorn Helgaas
ACPI Platform Error Interfaces (APEI) convey error information to the OS. If the APEI GHES driver receives information about PCI errors, it queues it in aer_recover_ring for processing by the PCI AER code. AER_RECOVER_RING_SIZE is the size of the aer_recover_ring FIFO and is arbitrary, with no direct connection to hardware. AER_RECOVER_RING_ORDER was only used to compute AER_RECOVER_RING_SIZE. Remove it and define AER_RECOVER_RING_SIZE directly. No functional change intended.

2023-08-25x86/sev: Make enc_dec_hypercall() accept a size instead of npagesSteve Rutherford
enc_dec_hypercall() accepted a page count instead of a size, which forced its callers to round up.

After rtw_usb_alloc_rx_bufs() has been called rx urbs have been allocated and must be freed in the error path. After rtw_usb_init_rx() has been called they are submitted, so they also must be killed. Add these forgotten steps to the probe error path. Besides the lost memory this also fixes a problem when the driver fails to download the firmware in rtw_chip_info_setup(). In this case it can happen that the completion of the rx urbs handler runs at a time when we already freed our data structures resulting in a kernel crash.

Clang is a little more pedantic than GCC, which does not warn when falling through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst, which states that all switch/case blocks must end in either break, fallthrough, continue, goto, or return.

2023-08-25wifi: rtw89: phy: add phy_gen_def::cr_base to support WiFi 7 chipsPing-Ke Shih
cr_base is base address of PHY control register. The base of WiFi 6 and 7 chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly. For example, if PHY address is 0x1330, absolute address is 0x1_1330 for WiFi 6 chips, and 0x2_1330 for WiFi 7 chips. Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1. The offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are 0x2_0000 and 0x4_0000 respectively.

2023-08-25wifi: rtw89: mac: define register address of rx_filter to generalize codePing-Ke Shih
rx_filter is used to decide which kind of packets are received to driver, or just dropped by MAC layer to reduce bus traffic. The bit definitions of old and new chips are the sames, but only address is changed, so define a field to generalize usage.

2023-08-25wifi: rtw89: mac: generalize code to indirectly access WiFi internal memoryPing-Ke Shih
To diagnose abnormal behavior, we need to dump certain internal memory. For example, dump security CAM when debugging encryption/decryption problems, or dump BA CAM when debugging abnormal BlockAck. Since the indirect address and internal memory base address are different between WiFi 6 and 7 chips, add fields to reuse codes. Also, only WiFi 6 chips initialize DMAC and CMAC tables via this indirect interface, so no need to change the constant register address, and new firmware will help to initialize these tables.

2023-08-25wifi: rtw89: mac: add mac_gen_def::band1_offset to map MAC band1 register ↵Ping-Ke Shih
address There are two copies of MAC hardware called band0 and band1. Basically, the only difference between them is base address, so we can share functions with a 'band' (or 'mac_idx') argument. The offset of base address of WiFi 6 and 7 are 0x2000 and 0x4000 respectively, so add band1_offset field to new introduced struct mac_gen_def to possibly reuse functions. Using below spatch script to convert callers: @@ expression reg, band; @@ - rtw89_mac_reg_by_idx(reg, band) + rtw89_mac_reg_by_idx(rtwdev, reg, band) @@ expression reg, port, band; @@ - rtw89_mac_reg_by_port(reg, port, band) + rtw89_mac_reg_by_port(rtwdev, reg, port, band) Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230822125822.23817-2-pkshih@realtek.com

2023-08-25wifi: rtw89: initialize multi-channel handlingZong-Zhe Yang
We prepare to deal with multiple channels via new entity modes. * MCC_PREPARE: Transitional mode before MCC * MCC: Multi-Channel Concurrent mode And, enum of sub-entity is extended for second channel context. We add the entry flow of multi-channel handling and the core stuffs for extended index of sub-entity. And, we now deal with the filling of entity channels' info in entity recalc where we know the number of active chanctx. However, the other detail coding of MCC start/stop will be implemented in the following. Besides, chanctx listener struct is pre-added in chip info. Each component can add callback type in chanctx listener and configure its callback function to react according to chanctx states. We know at least RFK (RF calibration) and BTC (BT coexistence) will require such callbacks.

Callers call renew function when wanting to generate a new P2P NoA information element, and call append function to append NoA attribute one by one. Then, updating beacon work will fetch the P2P NoA information element configured by callers and add it to beacon. The use case of MCC (multi-channel concurrent) <GO + STA> for example: * start MCC - GO part renew P2P NoA append period NoA after calculation * download beacon for GO fetch P2P NoA and add to beacon content * stop MCC - GO part renew P2P NoA (reset) Signed-off-by: Zong-Zhe Yang <kevin_yang@realtek.com> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230816082133.57474-6-pkshih@realtek.com
