NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch.

When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly.

The mvpp2 is going to be extended to support the Marvell Armada 7K/8K platform, which is ARM64. As a preparation to this work, this commit enables building the mvpp2 driver on ARM64, by: - Adjusting the Kconfig dependency - Fixing the types used in the driver so that they are 32/64-bits compliant. We use dma_addr_t for DMA addresses, and unsigned long for virtual addresses. It is worth mentioning that after this commit, the driver is for now still only used on 32-bits platforms, and will only work on 32-bits platforms.

This commit adapts the mvpp2 RX path to use the build_skb() method. Not only build_skb() is now the recommended mechanism, but it also simplifies the addition of support for the PPv2.2 variant. Indeed, without build_skb(), we have to keep track for each RX descriptor of the physical address of the packet buffer, and the virtual address of the SKB. However, in PPv2.2 running on 64 bits platform, there is not enough space in the descriptor to store the virtual address of the SKB. So having to take care only of the address of the packet buffer, and building the SKB upon reception helps in supporting PPv2.2. The implementation is fairly straightforward: - mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer allocates a SKB. Instead, it allocates a buffer using the new mvpp2_frag_alloc() function, with enough space for the data and SKB. - The initialization of the RX buffers in mvpp2_bm_bufs_add() as well as the refill of the RX buffers in mvpp2_rx_refill() is adjusted accordingly. - Finally, the mvpp2_rx() is modified to use build_skb().

Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which doesn't compile nicely on 64-bit. Moreover, those definitions are in fact unneeded, since they are always used in combination with a bit mask that ensures only the appropriate bits are modified. Therefore, such definitions should just be set to 0x0. In addition, as suggested by Russell King, we change the _MASK definitions to also use the BIT() macro so that it is clear they are related to the values defined afterwards. For example: #define MVPP2_PRS_RI_L2_CAST_MASK 0x600 #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) becomes #define MVPP2_PRS_RI_L2_CAST_MASK (BIT(9) | BIT(10)) #define MVPP2_PRS_RI_L2_UCAST 0x0 #define MVPP2_PRS_RI_L2_MCAST BIT(9) #define MVPP2_PRS_RI_L2_BCAST BIT(10) Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and MVPP2_PRS_RI_L2_BCAST) are always applied with MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)). It fixes the following warnings when building the driver on a 64-bit platform (which is not possible as of this commit, but will be enabled in a follow-up commit): drivers/net/ethernet/marvell/mvpp2.c: In function ‘mvpp2_prs_mac_promisc_set’: drivers/net/ethernet/marvell/mvpp2.c:524:33: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define MVPP2_PRS_RI_L2_UCAST ~(BIT(9) | BIT(10)) ^ drivers/net/ethernet/marvell/mvpp2.c:1459:33: note: in expansion of macro ‘MVPP2_PRS_RI_L2_UCAST’ mvpp2_prs_sram_ri_update(&pe, MVPP2_PRS_RI_L2_UCAST, Signed-off-by: NThomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: NRussell King <rmk+kernel@armlinux.org.uk> Signed-off-by: NDavid S.
