* wifi: ath9k: fix printk specifierDongliang Mu2023-07-251-2/+2
| | | | | | | | | | | | | | | | | | | | Smatch reports: ath_pci_probe() warn: argument 4 to %lx specifier is cast from pointer ath_ahb_probe() warn: argument 4 to %lx specifier is cast from pointer Fix it by modifying %lx to %p in the printk format string. Note that with this change, the pointer address will be printed as a hashed value by default. This is appropriate because the kernel should not leak kernel pointers to user space in an informational message. If someone wants to see the real address for debugging purposes, this can be achieved with the no_hash_pointers kernel option.

* ath9k: Check the return value of pcie_capability_read_*()Bolarinwa Olayemi Saheed2020-07-201-2/+3
| | | | | | | | | | | | | | | | On failure pcie_capability_read_dword() sets it's last parameter, val to 0. However, with Patch 14/14, it is possible that val is set to ~0 on failure. This would introduce a bug because (x & x) == (~0 & x). This bug can be avoided without changing the function's behaviour if the return value of pcie_capability_read_dword is checked to confirm success. Check the return value of pcie_capability_read_dword() to ensure success.

* ath9k: Really fix LED polarity for some Mini PCI AR9220 MB92 cards.Vittorio Gambaletta (VittGam)2016-11-151-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The active_high LED of my Wistron DNMA-92 is still being recognized as active_low on 4.7.6 mainline. When I was preparing my former commit 0f9edcdd88a9 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards.") to fix that I must have somehow messed up with testing, because I tested the final version of that patch before sending it, and it was apparently working; but now it is not working on 4.7.6 mainline. I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the PCI_VDEVICE section for 0x0029; but then I moved the former below the latter after seeing how 0x002A sections were sorted in the file. This turned out to be wrong: if a generic PCI_VDEVICE entry (that has both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will match first and will be used. With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6. While I'm at it, let's fix 0x002A too by also moving its generic definition below its specific ones.

* ath9k: simplify the code-paths when not using the built-in EEPROMMartin Blumenstingl2016-07-191-30/+13
| | | | | | | | | | | | There were two paths in the code for "external" eeprom sources. The code in eeprom.c only handled the cases where the eeprom data was loaded via request_firmware. ahb.c and pci.c on the other hand had some duplicate code which was only used when the eeprom data was passed via ath9k_platform_data.

To fix this, force the PLL to always be on using a different initval array, ar9485_1_1_pll_on_cdr_on_clkreq_disable_L1. This is done for most of the AR9485 based cards like HB125, WB225 etc. but certain models require the feature to be turned off. Identify such cards and use default values for them.

| * ath9k: Use standard #defines for PCIe Capability ASPM fieldsBjorn Helgaas2012-12-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | Use the standard #defines for PCIe Capability ASPM fields. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
* | ath9k: use SIMPLE_DEV_PM_OPSHauke Mehrtens2012-11-301-11/+4
| | | | | | | | | | | | | | | | | | | | ath9k does not provide any runtime pm callbacks, so support for PM_RUNTIME is not needed and we could go to PM_SLEEP. This also makes it possible to use SIMPLE_DEV_PM_OPS instead of manually filling struct dev_pm_ops. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

* ath9k: improve suspend/resume reliabilityFelix Fietkau2012-10-051-1/+3
| | | | | | | | | | Ensure that drv_start() always returns true, as a failing hw start usually eventually leads to crashes when there's still a station entry present. Call a power-on reset after a resume and after a hw reset failure to bring the hardware back to life again. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* ath9k: fix ASPM initialization on resumeFelix Fietkau2012-10-051-0/+5

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.
