* scsi: lpfc: Finalize Kconfig options for nvmeJames Smart2017-03-151-14/+0
| | | | | | | | | | | | | | | | | | | | Reviewing the result of what was just added for Kconfig, we made a poor choice. It worked well for full kernel builds, but not so much for how it would be deployed on a distro. Here's the final result: - lpfc will compile in NVME initiator and/or NVME target support based on whether the kernel has the corresponding subsystem support. Kconfig is not used to drive this specifically for lpfc. - There is a module parameter, lpfc_enable_fc4_type, that indicates whether the ports will do FCP-only or FCP & NVME (NVME-only not yet possible due to dependency on fc transport). As FCP & NVME divvys up exchange resources, and given NVME will not be often initially, the default is changed to FCP only.

* g_ncr5380: Remove CONFIG_SCSI_GENERIC_NCR53C400Finn Thain2016-04-111-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change brings a number of improvements: fewer macros, better test coverage, simpler code and sane Kconfig options. The downside is a small chance of incompatibility (which seems unavoidable). CONFIG_SCSI_GENERIC_NCR53C400 exists to enable or inhibit pseudo DMA transfers when the driver is used with 53C400-compatible cards. Thanks to Ondrej Zary's patches, PDMA now works which means it can be enabled unconditionally. Due to bad design, CONFIG_SCSI_GENERIC_NCR53C400 ties together unrelated functionality as it sets both PSEUDO_DMA and BIOSPARAM macros. This patch effectively enables PSEUDO_DMA and disables BIOSPARAM. The defconfigs and the Kconfig default leave CONFIG_SCSI_GENERIC_NCR53C400 undefined. Red Hat 9 and CentOS 2.1 were the same. This leaves both PSEUDO_DMA and BIOSPARAM disabled. The effect of this patch should be better performance from enabling PSEUDO_DMA. On the other hand, Debian 4 and SLES 10 had CONFIG_SCSI_GENERIC_NCR53C400 enabled, so both PSEUDO_DMA and BIOSPARAM were enabled. This patch might affect configurations like this by disabling BIOSPARAM. My best guess is that this could be a problem only in the vanishingly rare case that 1) the CHS values stored in the boot device partition table are wrong and 2) a 5380 card is in use (because PDMA on 53C400 used to be broken).

We could easily get rid of that by instead using separate arrays for the codes and the pointers. However, we can do even better than that and save an additional 6 bytes per entry: In the table, just store the sizeof() the corresponding string literal. The cumulative sum of these is then the appropriate offset into additional_text, which is built from the concatenation (with '\0's inbetween) of the strings. $ scripts/bloat-o-meter /tmp/vmlinux vmlinux add/remove: 0/0 grow/shrink: 1/1 up/down: 24/-8488 (-8464) function old new delta scsi_extd_sense_format 136 160 +24 additional 11312 2824 -8488 The Kconfig help text used to say that CONFIG_SCSI_CONSTANTS=y costs around 75 KB, but that was a little exaggerated.

Move the Toshiba CD-ROM support into the core driver, enabled with a host flag, so that all NCR5380 drivers can make use of it. Drop the RESET_BOOT macros and the ATARI_SCSI_RESET_BOOT and ATARI_SCSI_TOSHIBA_DELAY Kconfig symbols, which are now redundant. Remove the atari_scsi_reset_boot(), mac_scsi_reset_boot() and sun3_scsi_reset_boot() routines. None of this duplicated code is needed now that all drivers can use NCR5380_maybe_reset_bus(). This brings atari_scsi, mac_scsi and sun3_scsi into line with all of the other NCR5380 drivers. The bus reset may raise an interrupt. That would be new behaviour for atari_scsi only when CONFIG_ATARI_SCSI_RESET_BOOT=n. The ST DMA interrupt is not assigned to atari_scsi at this stage, so CONFIG_ATARI_SCSI_RESET_BOOT=y may well be problematic already. Regardless, do_reset() now raises and clears the interrupt within local_irq_save/restore which should avoid problems.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current discovery routines use the VPD 0x83 inquiry page to find the device SAS address and match it to the end point in the enclosure. This doesn't work for SATA devices because expanders (or hosts) simply make up an endpoint address for STP and thus the address returned by the VPD page never matches. Instead of doing this, for SAS attached devices, match by the direct endpoint address instead. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
