Internal functions for registers and HW access were not prefixed. This introduce noise in global kernel symbols. Here we add explicit prefix 'hw_atl' to all the HW access layer functions. Alignment and styling were fixed as well. Signed-off-by:

Original driver code had internal registers and masks declarations in low case and without any prefix. Here we make all these uppercase and add already used HW_ATL prefix to recognize these. Signed-off-by:

aq_nic_s was hidden in aq_nic_internal.h, that made it difficult to access nic fields and structures from other modules. This change moves aq_nic_s struct into aq_nic.h and thus makes it available to other driver modules, mainly pci module and hw related module. Signed-off-by:

Aleksey Makarov says: ==================== net: thunderx: add support for PTP clock This series adds support for IEEE 1588 Precision Time Protocol to Cavium ethernet driver. The first patch adds support for the Precision Time Protocol Clocks and Timestamping coprocessor (PTP) found on Cavium processors. It registers a new PTP clock in the PTP core and provides functions to use the counter in BGX, TNS, GTI, and NIC blocks. The second patch introduces support for the PTP protocol to the Cavium ThunderX ethernet driver. v6: - check if ptp_clock_register() returns NULL (Richard Cochran) - fix doc comment for cavium_ptp_enable() (Richard Cochran) - fix a function call formatting; use defined constant (Richard Cochran) - add comments for `tx_ptp_skbs` and `ptp_skb` (Richard Cochran) - use adjfine() instead of adjfreq() (Richard Cochran) - add Acked-by: Philippe Ombredanne <pombredanne@nexb.com> v5: https://lkml.kernel.org/r/20171211141435.2915-1-aleksey.makarov@cavium.com - fix the file headers (add SPDX tags, remove advertisment) (Philippe Ombredanne) - use "imply" instead of "select" (Richard Cochran) - add some code in cavium_ptp_get() for the case when the PTP driver has not been registered with the PTP core v4: https://lkml.kernel.org/r/20171208103442.19354-1-aleksey.makarov@cavium.com - use IS_ENABLED.

This adds timestamping support for both receive and transmit paths. On the receive side no filters are supported i.e either all pkts will get a timestamp appended infront of the packet or none. On the transmit side HW doesn't support timestamp insertion but only generates a separate CQE with transmitted packet's timestamp. Also HW supports only one packet at a time for timestamping on the transmit side. Signed-off-by:

Jiri Pirko says: ==================== devlink: Add support for resource abstraction Arkadi says: Many of the ASIC's internal resources are limited and are shared between several hardware procedures. For example, unified hash-based memory can be used for many lookup purposes, like FDB and LPM. In many cases the user can provide a partitioning scheme for such a resource in order to perform fine tuning for his application. In such cases performing driver reload is needed for the changes to take place, thus this patchset also adds support for hot reload. Such an abstraction can be coupled with devlink's dpipe interface, which models the ASIC's pipeline as a graph of match/action tables. By modeling the hardware resource object, and by coupling it to several dpipe tables, further visibility can be achieved in order to debug ASIC-wide issues. The proposed interface will provide the user the ability to understand the limitations of the hardware, and receive notification regarding its occupancy. Furthermore, monitoring the resource occupancy can be done in real-time and can be useful in many cases. --- v2->v3 - Mix/Max/Gran attributes. - Add resource consumption per table. - Change basic resource unit to 'entry'. - ABI documentation. v1->v2 - Add resource size attribute. - Fix split bug. ==================== Signed-off-by: -

Add support for hot reload. First, all the driver/core resources are released but the PCI and devlink instances, then reset is performed through the PCI interface. Finally the driver performs initialization. In case of reload failure the driver is left in a partially initialized state. Special care is taken during the driver removal in order to properly handle this state. Signed-off-by:

Arkadi Sharshevsky authored
Add support for hardware resource abstraction over devlink. Each resource is identified via id, furthermore it contains information regarding its size and its related sub resources. Each resource can also provide its current occupancy. In some cases the sizes of some resources can be changed, yet for those changes to take place a hot driver reload may be needed. The reload capability will be introduced in the next patch. Signed-off-by:

Arkadi Sharshevsky authored
This is a preparation before introducing resources and hot reload support. Currently there are two global lock where one protects all devlink access, and the second one protects devlink port access. This patch adds per devlink instance lock which protects the internal members which are the sb/dpipe/ resource/ports. By introducing this lock the global devlink port lock can be discarded.

He has been maintaining rtlwifi since it was applied back in 2010 in commit 0c817338 ("rtl8192ce: Add new driver") and it has been no easy role trying to juggle between the vendor, demanding upstream community and users.

The Gemini ethernet has been around for years as an out-of-tree patch used with the NAS boxen and routers built on StorLink SL3512 and SL3516, later Storm Semiconductor, later Cortina Systems. These ASICs are still being deployed and brand new off-the-shelf systems using it can easily be acquired. The full name of the IP block is "Net Engine and Gigabit Ethernet MAC" commonly just called "GMAC". The hardware block contains a common TCP Offload Enginer (TOE) that can be used by both MACs. The current driver does not use it. Cc: Tobias Waldvogel <tobias.waldvogel@gmail.com> Signed-off-by:

In commit 232d07b7 ("tipc: improve groupcast scope handling") we inadvertently broke non-group multicast transmission when changing the parameter 'domain' to 'scope' in the function tipc_nametbl_lookup_dst_nodes(). We missed to make the corresponding change in the calling function, with the result that the lookup always fails. A closer anaysis reveals that this parameter is not needed at all. Non-group multicast is hard coded to use CLUSTER_SCOPE, and in the current implementation this will be delivered to all matching destinations except those which are published with NODE_SCOPE on other nodes. Since such publications never will be visible on the sending node anyway, it makes no sense to discriminate by scope at all. We now remove this parameter altogether. Signed-off-by:

Since net could be obtained from RCU lists, and there is a race with net destruction, the patch converts net::count to refcount_t. This provides sanity checks for the cases of incrementing counter of already dead net, when maybe_get_net() has to used instead of get_net(). Drivers: allyesconfig and allmodconfig are OK.
