* net: fec: Do not use netdev messages too earlyFabio Estevam2019-06-061-3/+3
| | | | | | | | | | | | | | | | | | | | When a valid MAC address is not found the current messages are shown: fec 2188000.ethernet (unnamed net_device) (uninitialized): Invalid MAC address: 00:00:00:00:00:00 fec 2188000.ethernet (unnamed net_device) (uninitialized): Using random MAC address: aa:9f:25:eb:7e:aa Since the network device has not been registered at this point, it is better to use dev_err()/dev_info() instead, which will provide cleaner log messages like these: fec 2188000.ethernet: Invalid MAC address: 00:00:00:00:00:00 fec 2188000.ethernet: Using random MAC address: aa:9f:25:eb:7e:aa Tested on a imx6dl-pico-pi board.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | The phylink conflict was between a bug fix by Russell King to make sure we have a consistent PHY interface mode, and a change in net-next to pull some code in phylink_resolve() into the helper functions phylink_mac_link_{up,down}() On the dp83867 side it's mostly overlapping changes, with the 'net' side removing a condition that was supposed to trigger for RGMII but because of how it was coded never actually could trigger.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add hardware timestamping support for ENETC. On Rx, timestamping is enabled for all frames. On Tx, we only instruct the hardware to timestamp the frames marked accordingly by the stack. Because the RX BD ring dynamic allocation has not been supported and it is too expensive to use extended RX BDs if timestamping is not used, a Kconfig option is used to enable extended RX BDs in order to support hardware timestamping. This option will be removed once RX BD ring dynamic allocation is implemented.

* | Revert "dpaa2-eth: configure the cache stashing amount on a queue"Ioana Radulescu2019-05-231-6/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f8b995853444aba9c16c1ccdccdd397527fde96d. The reverted change instructed the QMan hardware block to fetch RX frame annotation and beginning of frame data to cache before the core would read them. It turns out that in rare cases, it's possible that a QMan stashing transaction is delayed long enough such that, by the time it gets executed, the frame in question had already been dequeued by the core and software processing began on it. If the core manages to unmap the frame buffer _before_ the stashing transaction is executed, an SMMU exception will be raised. Unfortunately there is no easy way to work around this while keeping the performance advantages brought by QMan stashing, so disable it altogether.

These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up. These diffstats are not small, 3840 files are touched, over 10k lines removed in just 24 patches" * tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (24 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 25 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 24 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 23 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 22 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 21 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 20 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 19 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 18 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 17 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 15 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 14 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 13 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 12 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 11 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 10 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 9 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 7 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 5 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 4 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 3 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms that lack a TCAM (like LS1088A), masking of flow steering keys is not supported. Until now we didn't offer flow steering capabilities at all on these platforms, since our driver implementation configured a "comprehensive" FS key (containing all supported header fields), with masks used to ignore the fields not present in the rules provided by the user. We now allow ethtool rules that share a common key (i.e. have the same header fields). The FS key is now kept in the driver private data and initialized when the first rule is added to an empty table, rather than at probe time. If a rule with a new composition key is wanted, the user must first manually delete all previous rules. When building a FS table entry to pass to firmware, we still use the old building algorithm, which assumes an all-supported-fields key, and later collapse the fields which aren't actually needed. Masked rules are not supported; if provided, the mask value will be ignored. For firmware versions older than MC10.7.0 (that only offer the legacy ABIs for configuring distribution keys) flow steering without masking support remains unavailable.

This link will ensure that when a DPIO device, which is indirectly used by other devices, is unbound any consumer devices will be also unbound from their drivers. For example, any DPNI, bound to the dpaa2-eth driver, which is using DPIO devices will be unbound before its supplier device. Also, add a new parameter to the dpaa2_io_service_[de]register functions to specify the requesting device (ie the consumer).

What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.
