2024-07-15net: Add struct kernel_ethtool_ts_infoKory Maincent1-1/+1
In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

2024-04-08e1000e: Remove redundant runtime resume for ethtool_opsBjorn Helgaas1-56/+6
e60b22c5b7e5 ("e1000e: fix accessing to suspended device") added ethtool_ops.begin() and .complete(), which used pm_runtime_get_sync() to resume suspended devices before any ethtool_ops callback and allow suspend after it completed. 3ef672ab1862 ("e1000e: ethtool unnecessarily takes device out of RPM suspend") removed ethtool_ops.begin() and .complete() and instead did pm_runtime_get_sync() only in the individual ethtool_ops callbacks that access device registers. Subsequently, f32a21376573 ("ethtool: runtime-resume netdev parent before ethtool ioctl ops") added pm_runtime_get_sync() in the dev_ethtool() path, so the device is resumed before *any* ethtool_ops callback, as it was before 3ef672ab1862. Remove most runtime resumes from ethtool_ops, which are now redundant because the resume has already been done by dev_ethtool(). This is essentially a revert of 3ef672ab1862 ("e1000e: ethtool unnecessarily takes device out of RPM suspend"). There are a couple subtleties: - Prior to 3ef672ab1862, the device was resumed only for the duration of a single ethtool callback. 3ef672ab1862 changed e1000_set_phys_id() so the device was resumed for ETHTOOL_ID_ACTIVE and remained resumed until a subsequent callback for ETHTOOL_ID_INACTIVE. Preserve that part of 3ef672ab1862 so the device will not be runtime suspended while in the ETHTOOL_ID_ACTIVE state. - 3ef672ab1862 added "if (!pm_runtime_suspended())" in before reading the STATUS register in e1000_get_settings(). This was racy and is now unnecessary because dev_ethtool() has resumed the device already, so revert that.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher1-2/+0
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

2019-06-28e1000e: Reduce boot time by tightening sleep rangesArjan van de Ven1-7/+7
The e1000e driver is a great user of the usleep_range() API, and has nice ranges that in principle help power management. However the ranges that are used only during system startup are very long (and can add easily 100 msec to the boot time) while the power savings of such long ranges is irrelevant due to the one-off, boot only, nature of these functions. This patch shrinks some of the longest ranges to be shorter (while still using a power friendly 1 msec range); this saves 100msec+ of boot time on my BDW NUCs Signed-off-by: Arjan van de Ven <[email protected]> Signed-off-by: Paul Menzel <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook1-2/+2
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2014-05-13net: get rid of SET_ETHTOOL_OPSWilfried Klaebe1-1/+1
net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.

2014-03-07e1000e: Refactor PM flowsDavid Ertman1-3/+3
Refactor the system power management flows to prevent the suspend path from being executed twice when hibernating since both the freeze and poweroff callbacks were set to e1000_suspend() via SET_SYSTEM_SLEEP_PM_OPS. There are HW workarounds that are performed during this flow and calling them twice was causing erroneous behavior. Re-arrange the code to take advantage of common code paths and explicitly set the individual dev_pm_ops callbacks for suspend, resume, freeze, thaw, poweroff and restore. Add a boolean parameter (reset) to the e1000e_down function to allow for cases when the HW should not be reset when downed during a PM event. Now that all suspend/shutdown paths result in a call to __e1000_shutdown() that checks Wake on Lan status, removing redundant check for WoL in e1000_power_down_phy().

2013-09-13e1000e: fix overrun of PHY RAR arrayDavid Ertman1-0/+8
When copying the MAC RAR registers to PHY there is an error in the calculation of the rar_entry_count, which causes a write of unknown/ undefined register space in the MAC to unknown/undefined register space in the PHY. This patch fixes the overrun with writing to the PHY RAR and also fixes the ethtool offline register tests so that the correctly addressed registers have the appropriate bitmasks for R/W and RO bits for affected parts. Shawn Rader gets credit for finding and fixing the register overrun.

2013-07-28e1000e: ethtool unnecessarily takes device out of RPM suspendBruce Allan1-28/+77
A previous patch (commit e60b22c5b7 e1000e: fix accessing to suspended device) added .begin and .complete ethtool driver callbacks so that the device was resumed from Runtime Power Management (RPM) suspend state for all ethtool operations. This is overkill for operations which do not need to access any registers in the device. This patch makes it so that the device is taken out of RPM suspend only for those ethtool operations that must access device registers.
