2025-02-10ice: Refactor ice_ptp_init_tx_*Karol Kolacinski2-39/+20
Unify ice_ptp_init_tx_* functions for most of the MAC types except E82X. This simplifies the code for the future use with new MAC types.

2025-02-10ice: Add unified ice_capture_crosststampJacob Keller1-75/+129
Devices supported by ice driver use essentially the same logic for performing a crosstimestamp. The only difference is that E830 hardware has different offsets. Instead of having multiple implementations, combine them into a single ice_capture_crosststamp() function. To support both hardware types, the ice_capture_crosststamp function must be able to determine the appropriate registers to access. To handle this, pass a custom context structure instead of the PF pointer. This structure, ice_crosststamp_ctx, contains a pointer to the PF, and a pointer to the device configuration structure. This new structure also will make it easier to implement historic snapshot support in a future commit. The device configuration structure is a static const data which defines the offsets and flags for the various registers. This includes the lock register, the cross timestamp control register, the upper and lower ART system time capture registers, and the upper and lower device time capture registers for each timer index. Use the configuration structure to access all of the registers in ice_capture_crosststamp(). Ensure that we don't over-run the device time array by checking that the timer index is 0 or 1. Previously this was simply assumed, and it would cause the device to read an incorrect and likely garbage register. It does feel like there should be a kernel interface for managing register offsets like this, but the closest thing I saw was <linux/regmap.h> which is interesting but not quite what we're looking for... Use rd32_poll_timeout() to read lock_reg and ctl_reg. Add snapshot system time for historic interpolation. Remove X86_FEATURE_ART and X86_FEATURE_TSC_KNOWN_FREQ from all E82X devices because those are SoCs, which will always have those features.

2025-02-10ice: Process TSYN IRQ in a separate functionKarol Kolacinski3-16/+57
Simplify TSYN IRQ processing by moving it to a separate function and having appropriate behavior per PHY model, instead of multiple conditions not related to HW, but to specific timestamping modes. When PTP is not enabled in the kernel, don't process timestamps and return IRQ_HANDLED.

2025-02-10ice: Remove unnecessary ice_is_e8xx() functionsKarol Kolacinski8-279/+147
Remove unnecessary ice_is_e8xx() functions and PHY model. Instead, use MAC type where applicable. Don't check device type in ice_ptp_maybe_trigger_tx_interrupt(), because in reality it depends on the ready bitmap, which only E810 does not have. Call ice_ptp_cfg_phy_interrupt() unconditionally, because all further function calls check the MAC type anyway and this allows simpler code in the future with addition of the new MAC types. Reorder ICE_MAC_* cases in switches in ice_ptp* as in enum ice_mac_type.

2025-02-10ice: Don't check device type when checking GNSS presenceKarol Kolacinski7-116/+105
Don't check if the device type is E810T as non-E810T devices can support GNSS too and PCA9575 check is enough to determine if GNSS is present or not. Rename ice_gnss_is_gps_present() to ice_gnss_is_module_present() because GNSS module supports multiple GNSS providers, not only GPS. Move functions related to PCA9575 from ice_ptp_hw.c to ice_common.c to be able to access them when PTP is disabled in the kernel, but GNSS is enabled. Remove logical AND with ICE_AQC_LINK_TOPO_NODE_TYPE_M in ice_get_pca9575_handle(), which has no effect, and reorder device type checks to check the device_id first, then set other variables.

2025-02-10netconsole: add support for sysdata and CPU populationBreno Leitao1-10/+43
Add infrastructure to automatically append kernel-generated data (sysdata) to netconsole messages. As the first use case, implement CPU number population, which adds the CPU that sent the message. This change introduces three distinct data types: - extradata: The complete set of appended data (sysdata + userdata) - userdata: User-provided key-value pairs from userspace - sysdata: Kernel-populated data (e.g. cpu=XX) The implementation adds a new configfs attribute 'cpu_nr' to control CPU number population per target. When enabled, each message is tagged with its originating CPU. The sysdata is dynamically updated at message time and appended after any existing userdata. The CPU number is formatted as "cpu=XX" and is added to the extradata buffer, respecting the existing size limits.

2025-02-10netconsole: Rename userdata to extradataBreno Leitao1-43/+44
Rename "userdata" to "extradata" since this structure will hold both user and system data in future patches. Keep "userdata" term only for data that comes from userspace (configfs), while "extradata" encompasses both userdata and future kerneldata. These are the rules of the design 1. extradata_complete will hold userdata and sysdata (coming) 2. sysdata will come after userdata_length 3. extradata_complete[userdata_length] string will be replaced at every message 5. userdata is replaced when configfs changes (update_userdata()) 6. sysdata is replaced at every message Example: extradata_complete = "userkey=uservalue cpu=42" userdata_length = 17 sysdata_length = 7 (space (" ") is part of sysdata) Since sysdata is still not available, you will see the following in the send functions: extradata_len = nt->userdata_length; The upcoming patches will, which will add support for sysdata, will change it to: extradata_len = nt->userdata_length + sysdata_len; Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.

This simplifies the code by: - Eliminating redundant static buffers - Centralizing buffer management in the target structure - Reducing memory usage by 1KB (one buffer instead of two) The buffer in netconsole_target is protected by target_list_lock, maintaining the same synchronization semantics as the original code.

2025-02-10wifi: rtw89: call power_on ahead before selecting firmwarePing-Ke Shih3-17/+36
Driver selects firmware by hardware version, which normally can be read from registers before selecting firmware. However, certain chips such as RTL8851B, it needs to read hardware version from efuse while doing power_on, but do power_on after selecting firmware in current flow. To resolve this flow problem, move power_on out from rtw89_mac_partial_init(), and call rtw89_mac_pwr_on() separately at proper places to have expected flow.

2025-02-09lib/crc32: standardize on crc32c() name for Castagnoli CRC32Eric Biggers1-1/+1
For historical reasons, the Castagnoli CRC32 is available under 3 names: crc32c(), crc32c_le(), and __crc32c_le(). Most callers use crc32c(). The more verbose versions are not really warranted; there is no "_be" version that the "_le" version needs to be differentiated from, and the leading underscores are pointless. Therefore, let's standardize on just crc32c(). Remove the other two names, and update callers accordingly. Specifically, the new crc32c() comes from what was previously __crc32c_le(), so compared to the old crc32c() it now takes a size_t length rather than unsigned int, and it's now in linux/crc32.h instead of just linux/crc32c.h (which includes linux/crc32.h). Later patches will also rename __crc32c_le_combine(), crc32c_le_base(), and crc32c_le_arch().

The driver assumed that es58x_dev->udev->serial could never be NULL. While this is true on commercially available devices, an attacker could spoof the device identity providing a NULL USB serial number. That would trigger a NULL pointer dereference. Add a check on es58x_dev->udev->serial before accessing it.
