In order to comply with SMBus specification, the Axxia I²C module will abort the multi message transfer if the delay between finishing sending one message and starting another is longer than 25ms. Unfortunately it isn't that hard to trigger this situation on a busy system. In order to fix this problem, we should make sure hardware does whole transaction without waiting for software to fill some data. Fortunately, in addition to Manual mode that is currently used by the driver to perform I²C transfers, the module supports also so called Sequence mode. In this mode, the module automatically performs predefined sequence of operations - it sends a slave address, transmits specified number of bytes from the FIFO, changes transfer direction, resends the slave address and then reads specified number of bytes to FIFO. While very inflexible, this does fit a most common case of multi message transfer - the one where you first write a register number you want to read and then read it. To use this mode effectively, a number of conditions must be met to ensure the transaction does fit the predefined sequence. In case this is not the case, a fallback to manual mode is used. The initialization of this mode is very similar to Manual mode. The most notable difference is different bit in the Master Interrupt Status designating finishing of transaction. Also some of the errors, like TSS, cannot happen in this mode. While it is possible to support transactions requesting a read of any size (RFL interrupt will be generated when FIFO size is not enough) the TFL interrupt is not available in this mode, thus the write part of the transaction cannot exceed FIFO_SIZE (8). Note that in case of a NAK during transaction, the NA/ND status bits will be set before STOP command is generated, triggering an interrupt while the controller is still busy. Current solution for this problem is to actively wait for this command to stop before leaving xfer callback. Signed-off-by:

It was observed that when using seqentional mode contrary to the documentation, the SS bit (which is supposed to only be set if automatic/sequence command completed normally), is sometimes set together with NA (NAK in address phase) causing transfer to falsely be considered successful. My assumption is that this does not happen during manual mode since the controller is stopping its work the moment it sets NA/ND bit in status register. This is not the case in Automatic/Sequentional mode where it is still working to send STOP condition and the actual status we get depends on the time when the ISR is run. This patch changes the order of checking status bits in ISR - error conditions are checked first and only if none of them occurred, the transfer may be considered successful. This is required to introduce using of sequentional mode in next patch. Signed-off-by:

The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by:

The new 57500 chips have introduced the NQ structure in addition to the existing CP rings in all chips. We need to introduce a new bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the same and one will just call the other. On the new chips, they refer to the 2 separate ring structures. The new function is now called to determine the resource (NQ or CP rings) associated with MSIX that are in use. On 57500 chips, the RDMA driver does not use the CP rings so we don't need to do the subtraction adjustment. Fixes: 41e8d798 ("bnxt_en: Modify the ring reservation functions for 57500 series chips.")

The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use 1 CP ring per MSIX vector. To better unify this, add a resv_irqs field to struct bnxt_hw_resc. On legacy chips, we initialize resv_irqs with resv_cp_rings. On new chips, we initialize it with the allocated MSIX resources. Signed-off-by:

Recent changes to support the 57500 devices have created this regression. The bnxt_hwrm_queue_qportcfg() call was moved to be called earlier before the RDMA support was determined, causing the CoS queues configuration to be set before knowing whether RDMA was supported or not. Fix it by moving it to the right place right after RDMA support is determined. Fixes: 98f04cf0 ("bnxt_en: Check context memory requirements from firmware.") Signed-off-by:

Pull libnvdimm fixes from Dan Williams: "A regression fix for the Address Range Scrub implementation, yes another one, and support for platforms that misalign persistent memory relative to the Linux memory hotplug section constraint. Longer term, support for sub-section memory hotplug would alleviate alignment waste, but until then this hack allows a 'struct page' memmap to be established for these misaligned memory regions. These have all appeared in a -next release, and thanks to Patrick for reporting and testing the alignment padding fix. Summary: - Unless and until the core mm handles memory hotplug units smaller than a section (128M), persistent memory namespaces must be padded to section alignment. The libnvdimm core already handled section collision with "System RAM", but some configurations overlap independent "Persistent Memory" ranges within a section, so additional padding injection is added for that case. - The recent reworks of the ARS (address range scrub) state machine to reduce the number of state flags inadvertantly missed a conversion of acpi_nfit_ars_rescan() call sites. Fix the regression whereby user-requested ARS results in a "short" scrub rather than a "long" scrub. - Fixup the unit tests to handle / test the 128M section alignment of mocked test resources. * tag 'libnvdimm-fixes-4.20-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: acpi/nfit: Fix user-initiated ARS to be "ARS-long" rather than "ARS-short" libnvdimm, pfn: Pad pfn namespaces relative to other regions tools/testing/nvdimm: Align test resources to 128M
