git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull EFI updates from Ingo Molnar: "The EFI changes in this cycle are much larger than usual, for two (positive) reasons: - The GRUB project is showing signs of life again, resulting in the introduction of the generic Linux/UEFI boot protocol, instead of x86 specific hacks which are increasingly difficult to maintain. There's hope that all future extensions will now go through that boot protocol. - Preparatory work for RISC-V EFI support. The main changes are: - Boot time GDT handling changes - Simplify handling of EFI properties table on arm64 - Generic EFI stub cleanups, to improve command line handling, file I/O, memory allocation, etc. - Introduce a generic initrd loading method based on calling back into the firmware, instead of relying on the x86 EFI handover protocol or device tree. - Introduce a mixed mode boot method that does not rely on the x86 EFI handover protocol either, and could potentially be adopted by other architectures (if another one ever surfaces where one execution mode is a superset of another) - Clean up the contents of 'struct efi', and move out everything that doesn't need to be stored there. - Incorporate support for UEFI spec v2.8A changes that permit firmware implementations to return EFI_UNSUPPORTED from UEFI runtime services at OS runtime, and expose a mask of which ones are supported or unsupported via a configuration table. - Partial fix for the lack of by-VA cache maintenance in the decompressor on 32-bit ARM. - Changes to load device firmware from EFI boot service memory regions - Various documentation updates and minor code cleanups and fixes" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) efi/libstub/arm: Fix spurious message that an initrd was loaded efi/libstub/arm64: Avoid image_base value from efi_loaded_image partitions/efi: Fix partition name parsing in GUID partition entry efi/x86: Fix cast of image argument efi/libstub/x86: Use ULONG_MAX as upper bound for all allocations efi: Fix a mistype in comments mentioning efivar_entry_iter_begin() efi/libstub: Avoid linking libstub/lib-ksyms.o into vmlinux efi/x86: Preserve %ebx correctly in efi_set_virtual_address_map() efi/x86: Ignore the memory attributes table on i386 efi/x86: Don't relocate the kernel unless necessary efi/x86: Remove extra headroom for setup block efi/x86: Add kernel preferred address to PE header efi/x86: Decompress at start of PE image load address x86/boot/compressed/32: Save the output address instead of recalculating it efi/libstub/x86: Deal with exit() boot service returning x86/boot: Use unsigned comparison for addresses efi/x86: Avoid using code32_start efi/x86: Make efi32_pe_entry() more readable efi/x86: Respect 32-bit ABI in efi32_pe_entry() efi/x86: Annotate the LOADED_IMAGE_PROTOCOL_GUID with SYM_DATA ...

2020-03-26scsi: ufs: Do not rely on prefetched dataCan Guo
We were setting bActiveICCLevel attribute for UFS device only once but the type of this attribute has changed from persistent to volatile since UFS device specification v2.1. This attribute is set to the default value after power cycle or hardware reset event. It isn't safe to rely on prefetched data (only used for bActiveICCLevel attribute now). Hence this change removes the code related to data prefetching and set this parameter on every attempt to probe the UFS device.

2020-03-26scsi: hpsa: correct race condition in offload enabledDon Brace
Correct race condition where ioaccel is re-enabled before the raid_map is updated. For RAID_1, RAID_1ADM, and RAID 5/6 there is a BUG_ON called which is bad. - Change event thread to disable ioaccel only. Send all requests down the RAID path instead. - Have rescan thread handle offload_enable. - Since there is only one rescan allowed at a time, turning offload_enabled on/off should not be racy. Each handler queues up a rescan if one is already in progress. - For timing diagram, offload_enabled is initially off due to a change (transformation: splitmirror/remirror), ... otbe = offload_to_be_enabled oe = offload_enabled Time Event Rescan Completion Request Worker Worker Thread Thread ---- ------ ------ ---------- ------- T0 | | + UA | T1 | + rescan started | 0x3f | T2 + Event | | 0x0e | T3 + Ack msg | | | T4 | + if (!dev[i]->oe && | | T5 | | dev[i]->otbe) | | T6 | | get_raid_map | | T7 + otbe = 1 | | | T8 | | | | T9 | + oe = otbe | | T10 | | | + ioaccel request T11 * BUG_ON T0 - I/O completion with UA 0x3f 0x0e sets rescan flag.

2020-03-26scsi: ufs: Enable block layer runtime PM for well-known logical unitsCan Guo
Block layer RPM is enabled for the genernal UFS SCSI devices when they are probed by their driver. However block layer RPM is not enabled for UFS well-known SCSI devices. As UFS SCSI devices have their corresponding BSG char devices, accessing a BSG char device via IOCTL may send requests to its corresponding SCSI device through its request queue. If BSG IOCTL sends a request to a well-known SCSI device when HBA is not runtime active, due to block layer RPM not being enabled for the well-known SCSI devices, the HBA, which is at the top of a SCSI device's parent chain, will not be resumed. This change enables block layer RPM for the well-known SCSI devices so that block layer can handle RPM for the well-known SCSI devices just like for the general SCSI devices.

If an iSCSI connection happens to fail while the daemon isn't running (due to a crash or for another reason), the kernel failure report is not received. When the daemon restarts, there is insufficient kernel state in sysfs for it to know that this happened. open-iscsi tries to reopen every connection, but on different initiators, we'd like to know which connections have failed. There is session->state, but that has a different lifetime than an iSCSI connection, so it doesn't directly reflect the connection state.

2020-03-24scsi: sd: Fix optimal I/O size for devices that change reported valuesMartin K. Petersen
Some USB bridge devices will return a default set of characteristics during initialization. And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.

Added the sysfs attribute for non fatal log so that management utility can get the non fatal dump from driver. The non-fatal error is an error condition or abnormal behavior detected by the host, or detected and reported by the controller to the host.The non-fatal error does not stop the controller firmware and enables it to still respond to host requests. A typical example of a non-fatal error is an I/O timeout or an unusual error notification from the controller. Since the firmware is operational, the error dump information is pushed to host memory (by firmware) upon request from the host.

2020-03-17scsi: pm80xx: Free the tag when mpi_set_phy_profile_resp is receivedyuuzheng
In pm80xx driver, the command mpi_set_phy_profile_req is sent by host during boot to configure the phy profile such as analog setting page, rate control page. However, the tag is not freed when its response is received. As a result, 16 tags are missing for each HBA after boot. When NCQ is enabled with queue depth 16, it needs at least, 15 * 16 = 240 tags for each HBA to achieve the best performance. In current pm80xx driver with setting CCB_MAX = 256, the total number of tags in each HBA is 255 for data IO. Hence, without returning those tags to the pool after boot, some device will finally be forced to non-ncq mode by ATA layer due to excessive errors (i.e. LLDD cannot allocate tag for queued task).

2020-03-17scsi: pm80xx: Increase request sg lengthPeter Chang
Increasing the per-request size maximum (max_sectors_kb) runs into the per-device DMA scatter gather list limit (max_segments) for users of the io vector system calls (eg, readv and writev). This is because the kernel combines io vectors into DMA segments when possible, but it doesn't work for our user because the vectors in the buffer cache get scrambled. This change bumps the advertised max scatter gather length to 528 to cover 2M w/ x86's 4k pages and some extra for the user checksum. It trims the size of some of the tables we don't care about and exposes all of the command slots upstream to the SCSI layer. Also reduced the PM8001_MAX_CCB to 256 as pm8001 driver has memory limit depend on machine capability. If we increase the sg length, we need to trade-off it by decreasing PM8001_MAX_CCB. PM8001_MAX_CCB = 256 does not have any influence on normal use Link: https://lore.kernel.org/r/20200316074906.9119-2-deepak.ukey@microchip.com Reported-by: kbuild test robot <lkp@intel.com> Acked-by: Jack Wang <jinpu.wang@cloud.ionos.com> Signed-off-by: Peter Chang <dpf@google.com> Signed-off-by: Deepak Ukey <deepak.ukey@microchip.com> Signed-off-by: Viswas G <Viswas.G@microchip.com> Signed-off-by: Radha Ramachandran <radha@google.com> Signed-off-by: Martin K.
