2020-03-02octeontx2-af: Modify rvu_reg_poll() to check reg atleast twiceSunil Goutham
Currently on the first check if the operation is still not finished, the poll goes to sleep for 2-5 usecs. But if for some reason (due to other priority stuff like interrupts etc) by the time the poll wakes up the 10ms time is expired then we don't check if operation is finished or not and return failure. This patch modifies poll logic to check HW operation after sleep so that the status is checked atleast twice. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2020-03-02octeontx2-af: Enable PCI masterSunil Goutham
Bus mastering is enabled by firmware, but when this driver is unbinded bus mastering gets disabled by the PCI subsystem which results interrupts not working when driver is reloaded. Hence set bus mastering everytime in probe(). Also - Converted pci_set_dma_mask() and pci_set_consistent_dma_mask() to dma_set_mask_and_coherent(). - Cleared transaction pending bit which gets set during driver unbind due to clearing of bus mastering (ME bit).

2020-03-02octeontx2-af: Set discovery ID for RVUM blockSunil Goutham
Currently there is no way for AF dependent drivers in any domain to check if the AF driver is loaded. This patch sets an ID for RVUM block which will automatically reflects in PF/VFs discovery register which they can check and defer their probe until AF is up.

2020-03-02octeontx2-af: Optimize data retrieval from firmwareLinu Cherian
For retrieving info like interface MAC addresses, packet parser key extraction config etc currently a command is sent to firmware and firmware which periodically polls for commands, processes these and returns the info. This is resulting in interface initialization taking lot of time. To optimize this a memory region is shared between firmware and this driver, firmware while booting puts static info like these into that region for driver to read directly without using commands. With this - Logic for retrieving packet parser extraction config via commands is removed and repalced with using the shared 'fwdata' structure. - Now RVU MSIX vector address is also retrieved from this fwdata struct instead of from CSR. Otherwise when kexec/kdump crash kernel loads CSR will have a IOVA setup by primary kernel which impacts RVU PF/VF's interrupts. - Also added a mbox handler for PF/VF interfaces to retrieve their MAC addresses from AF.

2020-03-02octeontx2-af: Interface backpressure configurationGeetha sowjanya
Each of the interface receive channels can be backpressured by resources upon exhaustion or reaching configured threshold levels. Resources here are receive buffer queues (Auras) and pkt notification descriptor queues (CQs). Resources and interface channels are mapped using backpressure IDs (BPIDs). HW supports upto 512 BPIDs, this patch divides these BPIDs statically across CGX/LBK/SDP interfaces as follows. BPIDs 0 - 191 are mapped to LMAC channels, 16 per LMAC. BPIDs 192 - 255 are mapped to LBK channels. BPIDs 256 - 511 are mapped to SDP channels. Also did the needed basic configuration of BPIDs. Added mbox handlers with which a PF device can request for a BPID which it will use to configure Auras and CQs.

2020-02-26net: marvell: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by: Gustavo A. R.

2020-02-20net: page_pool: API cleanup and commentsIlias Apalodimas
Functions starting with __ usually indicate those which are exported, but should not be called directly. Update some of those declared in the API and make it more readable. page_pool_unmap_page() and page_pool_release_page() were doing exactly the same thing calling __page_pool_clean_page(). Let's rename __page_pool_clean_page() to page_pool_release_page() and export it in order to show up on perf logs and get rid of page_pool_unmap_page(). Finally rename __page_pool_put_page() to page_pool_put_page() since we can now directly call it from drivers and rename the existing page_pool_put_page() to page_pool_put_full_page() since they do the same thing but the latter is trying to sync the full DMA area. This patch also updates netsec, mvneta and stmmac drivers which use those functions.

Only AF can configure a LF's contexts, so request AF to allocate memory for NPA aura/pool and NIX RQ/SQ/CQ HW contexts. Upon receiving response, save some of the HW constants like number of pointers per stack page, size of send queue buffer (SQBs, where SQEs are queued by HW) e.t.c which are later used to initialize queues.

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2020-01-05net: switch to using PHY_INTERFACE_MODE_10GBASER rather than 10GKRRussell King
Switch network drivers, phy drivers, and SFP/phylink over to use the more correct 10GBASE-R, rather than 10GBASE-KR. 10GBASE-KR is backplane ethernet, which is 10GBASE-R with autonegotiation on top, which our current usage on the affected platforms does not have. The only remaining user of PHY_INTERFACE_MODE_10GKR is the Aquantia PHY, which has a separate mode for 10GBASE-KR. For Marvell mvpp2, we detect 10GBASE-KR, and rewrite it to 10GBASE-R for compatibility with existing DT - this is the only network driver at present that makes use of PHY_INTERFACE_MODE_10GKR.

Pull networking fixes from David Miller: 1) Several nf_flow_table_offload fixes from Pablo Neira Ayuso, including adding a missing ipv6 match description. 2) Several heap overflow fixes in mwifiex from qize wang and Ganapathi Bhat. 3) Fix uninit value in bond_neigh_init(), from Eric Dumazet. 4) Fix non-ACPI probing of nxp-nci, from Stephan Gerhold. 5) Fix use after free in tipc_disc_rcv(), from Tuong Lien. 6) Enforce limit of 33 tail calls in mips and riscv JIT, from Paul Chaignon. 7) Multicast MAC limit test is off by one in qede, from Manish Chopra. 8) Fix established socket lookup race when socket goes from TCP_ESTABLISHED to TCP_LISTEN, because there lacks an intervening RCU grace period. From Eric Dumazet. 9) Don't send empty SKBs from tcp_write_xmit(), also from Eric Dumazet. 10) Fix active backup transition after link failure in bonding, from Mahesh Bandewar. 11) Avoid zero sized hash table in gtp driver, from Taehee Yoo. 12) Fix wrong interface passed to ->mac_link_up(), from Russell King. 13) Fix DSA egress flooding settings in b53, from Florian Fainelli. 14) Memory leak in gmac_setup_txqs(), from Navid Emamdoost. 15) Fix double free in dpaa2-ptp code, from Ioana Ciornei. 16) Reject invalid MTU values in stmmac, from Jose Abreu. 17) Fix refcount leak in error path of u32 classifier, from Davide Caratti. 18) Fix regression causing iwlwifi firmware crashes on boot, from Anders Kaseorg. 19) Fix inverted return value logic in llc2 code, from Chan Shu Tak. 20) Disable hardware GRO when XDP is attached to qede, frm Manish Chopra. 21) Since we encode state in the low pointer bits, dst metrics must be at least 4 byte aligned, which is not necessarily true on m68k. Add annotations to fix this, from Geert Uytterhoeven. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (160 commits) sfc: Include XDP packet headroom in buffer step size. sfc: fix channel allocation with brute force net: dst: Force 4-byte alignment of dst_metrics selftests: pmtu: fix init mtu value in description hv_netvsc: Fix unwanted rx_table reset net: phy: ensure that phy IDs are correctly typed mod_devicetable: fix PHY module format qede: Disable hardware gro when xdp prog is installed net: ena: fix issues in setting interrupt moderation params in ethtool net: ena: fix default tx interrupt moderation interval net/smc: unregister ib devices in reboot_event net: stmmac: platform: Fix MDIO init for platforms without PHY llc2: Fix return statement of llc_stat_ev_rx_null_dsap_xid_c (and _test_c) net: hisilicon: Fix a BUG trigered by wrong bytes_compl net: dsa: ksz: use common define for tag len s390/qeth: don't return -ENOTSUPP to userspace s390/qeth: fix promiscuous mode after reset s390/qeth: handle error due to unsupported transport mode cxgb4: fix refcount init for TC-MQPRIO offload tc-testing: initial tdc selftests for cls_u32 ...
