Broadcom: IT (HBA) Driver Enablement in 18.04 (Patches)

Also we have posted some patches to the upstream community and they are yet to be accepted by the upstream,

mpt3sas: Bug fix for big endian systems.

  mpt3sas: Pre-allocate RDPQ Array at driver boot time.

  mpt3sas: Lockless access for chain buffers.

  mpt3sas: Optimize I/O memory consumption in driver.

  mpt3sas: Enhanced handling of Sense Buffer.

  mpt3sas: Added support for SAS Device Discovery Error Event.

  mpt3sas: Increase event log buffer to support 24 port HBA's.

  mpt3sas: Allow processing of events during driver unload.

  mpt3sas: Cache enclosure pages during enclosure add.

  mpt3sas: Report Firmware Package Version from HBA Driver.

  mpt3sas: Update MPI Headers

  mpt3sas: For NVME device, issue a protocol level reset instead of

    hot reset and use TM timeout value exposed in PCIe Device Page 2.

  mpt3sas: fix possible memory leak.

  mpt3sas: Update driver version "25.100.00.00"

Currently we are waiting on the commit IDs for the patches listed in comment #1

Adding commit IDs for patches referenced above:

All these patches are queued for the next kernel (4.18) update in the SCSI branch. Once the window for the 4.18 is open, these patches will be pushed from SCSI branch to the tip kernel. Current tip kernel 4.17-rc7 doesn’t have these changes in it.

I built a Bionic test kernel with the requested 37 patches.

 The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1772434

Can you test this kernel and see if it resolves this bug?

Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

Thanks in advance!

Can you guys share the release plans for kernel-4.15.0-33.36?
We have a installation/boot failure with HBA330 and the patches in this list are fixing it.

Hi Sujith,

Do you know if the test kernel posted in comment #4 was tested? It's been some time, and I think we were waiting for the test result of that kernel before submitting the SRU request.
