One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct MR_PD_CFG_SEQ_NUM_SYNC { ... struct MR_PD_CFG_SEQ seq[1]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct MR_PD_CFG_SEQ_NUM_SYNC) + (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1)) with: struct_size(pd_sync, seq, MAX_PHYSICAL_DEVICES - 1) This code was detected with the help of Coccinelle.

A system bus error during a PDMA send operation can result in bytes being lost. Theoretically that could cause the target to remain in DATA OUT phase and the initiator (expecting a phase change) would time-out waiting for the Last Byte Sent flag. Should that happen, fail the transfer so the core driver will stop using PDMA with this target. Cc: Michael Schmitz <schmitzmic@gmail.com> Signed-off-by:

Add support for Apple's custom "SCSI DMA" chip. This patch doesn't make use of its DMA capability. Just the PDMA capability is sufficient to improve sequential read throughput by a factor of 5.

A system bus error during a PDMA transfer can mess up the calculation of the transfer residual (the PDMA handshaking hardware lacks a byte counter). This results in data corruption. The algorithm in this patch anticipates a bus error by starting each transfer with a MOVE.B instruction. If a bus error is caught the transfer will be retried. If a bus error is caught later in the transfer (for a MOVE.W instruction) the transfer gets failed and subsequent requests for that target will use PIO instead of PDMA. This avoids the "!REQ and !ACK" error so the severity level of that message is reduced to KERN_DEBUG.

Some targets introduce delays when handshaking the response to certain commands. For example, a disk may send a 96-byte response to an INQUIRY command (or a 24-byte response to a MODE SENSE command) too slowly. Apparently the first 12 or 14 bytes are handshaked okay but then the system bus error timeout is reached while transferring the next word. Since the scsi bus phase hasn't changed, the driver then sets the target borken flag to prevent further PDMA transfers. The driver also logs the warning, "switching to slow handshake". Raise the PDMA threshold to 512 bytes so that PIO transfers will be used for these commands. This default is sufficiently low that PDMA will still be used for READ and WRITE commands. The existing threshold (16 bytes) was chosen more or less at random. However, best performance requires the threshold to be as low as possible. Those systems that don't need the PIO workaround at all may benefit from mac_scsi.setup_use_pdma=1 Cc: Michael Schmitz <schmitzmic@gmail.com> Cc: stable@vger.kernel.org # v4.14+ Fixes: 3a0f64bf ("mac_scsi: Fix pseudo DMA implementation") Signed-off-by:

A PDMA error is handled in the core driver by setting the device's 'borken' flag and aborting the command. Unfortunately, do_abort() is not dependable. Perform a SCSI bus reset instead, to make sure that the command fails and gets retried.

The reselection interrupt gets disabled during selection and must be re-enabled when hostdata->connected becomes NULL. If it isn't re-enabled a disconnected command may time-out or the target may wedge the bus while trying to reselect the host. This can happen after a command is aborted. Fix this by enabling the reselection interrupt in NCR5380_main() after calls to NCR5380_select() and NCR5380_information_transfer() return.

This reverts commit 4822827a. The purpose of that commit was to suppress a timeout warning message which appeared to be caused by target latency. But suppressing the warning is undesirable as the warning may indicate a messed up transfer count. Another problem with that commit is that 15 ms is too long to keep interrupts disabled as interrupt latency can cause system clock drift and other problems.

Host reset oopses because it calls wd719x_chip_init, which calls request_firmware, under a spinlock. Stop the RISC first, then flush active SCBs under a spinlock. Finally call wd719x_chip_init unlocked. Also found and fixed more bugs during tests: Affected active SCBs were not flushed during abort, bus and device reset. This caused problems in a following host reset (hang or oops). Device and bus reset failed under load because the result of the reset command is WD719X_SUE_TERM or WD719X_SUE_RESET. Don't treat these codes as error in wd719x_wait_done. wd719x_direct_cmd for RESET/ABORT commands didn't work properly, causing timeouts. Looks like it was caused by the WD719X_DISABLE_INT bit. Not setting it for RESET/ABORT commands seems to fix the probem. Also lower the log level of the corresponding "direct command completed" message to debug. Unfortunately, my documentation is missing some pages, including page 67 (SPIDER67.gif) about resets :( Reported-by:

Several SCSI transport and LLD drivers surround code that does not tolerate concurrent calls of .queuecommand() with scsi_target_block() / scsi_target_unblock(). These last two functions use blk_mq_quiesce_queue() / blk_mq_unquiesce_queue() for scsi-mq request queues to prevent concurrent .queuecommand() calls. However, that is not sufficient to prevent .queuecommand() calls from scsi_send_eh_cmnd(). Hence surround the .queuecommand() call from the SCSI error handler with code that avoids that .queuecommand() gets called in the blocked state. Note: converting the .queuecommand() call in scsi_send_eh_cmnd() into code that calls blk_get_request() + blk_execute_rq() is not an option since scsi_send_eh_cmnd() must be able to make forward progress even if all requests have been allocated.

The ability to modify the SCSI device state was introduced by commit 638127e5 ("[PATCH] Fix error handler offline behaviour"; v2.6.12). That same commit introduced the following device states: { SDEV_CREATED, "created" }, { SDEV_RUNNING, "running" }, { SDEV_CANCEL, "cancel" }, { SDEV_DEL, "deleted" }, { SDEV_QUIESCE, "quiesce" }, { SDEV_OFFLINE, "offline" }, The SDEV_BLOCK state was introduced later to avoid that an FC cable pull would immediately result in an I/O error (commit 1094e682; "[PATCH] suspending I/Os to a device"; v2.6.12). That same patch introduced the ability to set the SDEV_BLOCK state from user space. I'm not sure whether that ability was introduced on purpose or accidentally. Since there is agreement that only writing "running" or "offline" into the SCSI sysfs device state attribute makes sense, restrict sysfs writes to these values. This patch makes sure that SDEV_BLOCK is only used for its original purpose, namely to allow transport drivers and LLDs to block further .queuecommand() calls while transport layer or adapter recovery is in progress. Note: a web search for "/sys/class/scsi_device" AND "device/state" revealed several storage configuration guides. The instructions I found in these guides tell users to write the value "running" or "offline" in the SCSI device state sysfs attribute and no other values.

1. Introduce module parameter perf_mode for only Aero/Sea generation HBAs. 2. Update IOC page1 fields according to performance mode. Below are the performance modes that can be enabled with module parameter perf_mode: 0: Balanced - Few high iops reply queues will be enabled. Interrupt coalescing will be enabled only for these high iops reply descriptor queues. 1: Iops - Interrupt coalescing will be enabled on all reply queues. Coalescing timeout is set to 0x20.This is default value for Aero. 2: Latency - Interrupt coalescing will be enabled on all reply queues. Coalescing timeout is set to 0xA. This is a legacy behavior similar to Ventura & Invader HBA series. Default perf mode set by driver will be balanced mode if the following conditions are met: - CPU vendor = Intel; - Aero controller working in 16GT/s pcie speed Performance mode will be set to latency mode for all other cases. 4k Random Read IO performance numbers on 24 SAS SSD drives for above three permormance modes. Performance data is from Intel Skylake and HGST SS300 (drive model SDLL1DLR400GCCA1).

Enable interrupt coalescing only on high iops queues. In ioc config page 1, offset 0x14 (ProductSpecific field) is used to determine interrupt coalescing enabled/disabled on per reply descriptor post queue group(8) basis. If 31st bit is zero, then interrupt coalescing is enabled for all reply descriptor post queues. If 31st bit is set to one, then user can enable/disable interrupt coalescing on per reply descriptor post queue group(8) basis. So to enable interrupt coalescing only on first reply descriptor post queue group (i.e. on high iops queues), set bit 0 and 31. This configuration should reset during driver unload or shutdown to the default settings. For this, the driver takes copy of default ioc page 1 and copies back the default or unmodified ioc page1 during unload and shutdown. This means that on next driver load (e.g. if older version driver is loaded by user), current modified changes on ioc page1 won't take effect. Signed-off-by:

High iops queues are mapped to non-managed irqs. Set affinity of non-managed irqs to local numa node. Low latency queues are mapped to managed irqs. Driver reserves some reply queues for max iops (through pci_alloc_irq_vectors_affinity and .pre_vectors interface). The rest of queues are for low latency. Based on io workload in io submission path, driver will decide which group of reply queues (either high iops queues or low latency queues) to be used. High iops queues will be mapped to local numa node of controller and low latency queues will be mapped to cpus across numa nodes. In general, high iops and low latency queues should fit into 128 reply queues which is the max number of reply queues supported by Aero/Sea. Signed-off-by:

Aero controllers support balanced performance mode through the ability to configure queues with different properties. Reply queues with interrupt coalescing enabled are called "high iops reply queues" and reply queues with interrupt coalescing disabled are called "low latency reply queues". The driver configures a combination of high iops and low latency reply queues if: - HBA is an AERO controller; - MSI-X vectors supported by the HBA is 128; - Total CPU count in the system more than high iops queue count; - Driver is loaded with default max_msix_vectors module parameter; and - System booted in non-kdump mode.

If the Aero HBA supports Atomic Request Descriptors, it sets the Atomic Request Descriptor Capable bit in the IOCCapabilities field of the IOCFacts Reply message. Driver uses an Atomic Request Descriptor as an alternative method for posting an entry onto a request queue. The posting of an Atomic Request Descriptor is an atomic operation, providing a safe mechanism for multiple processors on the host to post requests without synchronization. This Atomic Request Descriptor format is identical to first 32 bits of Default Request Descriptor and uses only 32 bits. Signed-off-by:
