Change that to always start one worker thread for every available CPU.

Add mechanism for automatic promotion of 4KB page mappings to 1MB section mappings (and demotion when not needed, respectively). 2. Managed and non-kernel mappings are now superpages-aware. 3. The functionality can be enabled by setting "vm.pmap.sp_enabled" tunable to a non-zero value (either in loader.conf or by modifying "sp_enabled" variable in pmap-v6.c file). By default, automatic promotion is currently disabled.

Add a PIM_NOSCAN flag to the CAM path inquiry CCB. This tells CAM not to perform a rescan on a bus when it is registered. We now use this flag in the mps(4) driver. Since it knows what devices it has attached, it is more efficient for it to just issue a target rescan on the targets that are attached. Also, remove the private rescan thread from the mps(4) driver in favor of the rescan thread already built into CAM. Without this change, but with the change above, the MPS scanner could run before or during CAM's initial setup, which would cause duplicate device reprobes and announcements. sys/param.h: Bump __FreeBSD_version to 1000039 for the inclusion of the PIM_RESCAN CAM path inquiry flag. sys/cam/cam_ccb.h: sys/cam/cam_xpt.c: Added a PIM_NOSCAN flag. If a SIM sets this in the path inquiry ccb, then CAM won't rescan the bus in xpt_bus_regsister. sys/dev/mps/mps_sas.c For versions of FreeBSD that have the PIM_NOSCAN path inquiry flag, don't freeze the sim queue during scanning, because CAM won't be scanning this bus. Instead, hold up the boot. Don't call mpssas_rescan_target in mpssas_startup_decrement; it's redundant and I don't know why it was in there. Set PIM_NOSCAN in path inquiry CCBs. Remove methods related to the internal rescan daemon. Always use async events to trigger a probe for EEDP support. In older versions of FreeBSD where AC_ADVINFO_CHANGED is not available, use AC_FOUND_DEVICE and issue the necessary READ CAPACITY manually. Provide a path to xpt_register_async() so that we only receive events for our own SCSI domain. Improve error reporting in cases where setup for EEDP detection fails. sys/dev/mps/mps_sas.h: Remove softc flags and data related to the scanner thread. sys/dev/mps/mps_sas_lsi.c: Unconditionally rescan the target whenever a device is added.

Added line to call the memory free function for mapping memory. --------------------------------------------------------------- Use CAM_SIM_QUEUED flag in Driver IO path. --------------------------------------------------------------- This flag informs the XPT that successful abort of a CCB requires an abort ccb to be issued to the SIM. While processing SCSI IO's, set the CAM_SIM_QUEUED flag in the status for the IO. When the command completes, clear this flag. --------------------------------------------------------------- Check for CAM_REQ_INPROG in I/O path. --------------------------------------------------------------- Added a check in mpssas_action_scsiio for the In Progress status for the IO. If this flag is set, the IO has already been aborted by the upper layer (before CAM_SIM_QUEUED was set) and there is no need to send the IO. The request will be completed without error. --------------------------------------------------------------- Improve "doorbell handshake method" for mps_get_iocfacts --------------------------------------------------------------- Removed call to get Port Facts since this information is not used currently. Added mps_iocfacts_allocate function to allocate memory that is based on IOC Facts data. Added mps_iocfacts_free function to free memory that is based on IOC Facts data. Both of the functions are used when a Diag Reset is performed or when the driver is attached/detached. This is needed in case IOC Facts changes after a Diag Reset, which could happen if FW is upgraded. Moved call of mps_bases_static_config_pages from the attach routine to after the IOC is ready to process accesses based on the new memory allocations (instead of polling through the Doorbell). --------------------------------------------------------------- Set TimeStamp in INIT message in millisecond format Set the IOC --------------------------------------------------------------- --------------------------------------------------------------- Prefer mps_wait_command to mps_request_polled --------------------------------------------------------------- Instead of using mps_request_polled, call mps_wait_command whenever possible. Change the mps_wait_command function to check the current context and either use interrupt context or poll if required by using the pause or DELAY function. Added a check after waiting 50mSecs to see if the command has timed out. This is only done if polliing, the msleep command will automatically timeout if the command has taken too long to complete. --------------------------------------------------------------- Integrated RAID: Volume Activation Failed error message is displayed though the volume has been activated. --------------------------------------------------------------- Instead of failing an IOCTL request that does not have a large enough buffer to hold the complete reply, copy as much data from the reply as possible into the user's buffer and log a message saying that the user's buffer was smaller than the returned data. --------------------------------------------------------------- mapping_add_new_device failure due to persistent table FULL --------------------------------------------------------------- When a new device is added, if it is determined that the device persistent table is being used and is full, instead of displaying a message for this condition every time, only log a message if the MPS_INFO bit is set in the debug_flags.

When the driver ran out of chain frames, the request in question would get completed early, and go through mpssas_scsiio_complete(). In mpssas_scsiio_complete(), the negation of the CAM status values (CAM_STATUS_MASK | CAM_SIM_QUEUED) was ORed in instead of being ANDed in. This resulted in a bogus CAM CCB status value. This didn't show up in the non-error case, because the status was reset to something valid (e.g. CAM_REQ_CMP) later on in the function. But in the error case, such as when the driver ran out of chain frames, the CAM_REQUEUE_REQ status was ORed in to the bogus status value. This led to the CAM transport layer repeatedly releasing the SIM queue, because it though that the CAM_RELEASE_SIMQ flag had been set. The symptom was messages like this on the console when INVARIANTS were enabled: xpt_release_simq: requested 1 > present 0 xpt_release_simq: requested 1 > present 0 xpt_release_simq: requested 1 > present 0 mps_sas.c: In mpssas_scsiio_complete(), use &= to take status bits out. |= adds them in.

MFC note: NFS implementation of VOP_READ() sometimes upgrades the vnode lock, which causes drop of the shared lock and sleep for exclusive. As result, busying of the page before the call to vn_rdwr() makes NFS code to wait for vnode lock while page is busy, which contradicts the proper order of vnode lock -> busy. The r250027, merged as part of r250907, started calling vm_page_grab() under the vnode lock. The page grab waits for the page busy state to drain, which makes the parallel sendfile(2) invocations on the same vnode vulnerable to the LOR described above. Note that r250027 only exposed the problem, which might be caused by other means as well, e.g. by parallel sendfile(2) and truncate(2).

Newer FreeBSD installs require an install(1) that supports the new flags. This adds ${MAKEOBJDIRPREFIX}${.CURDIR}/tmp/legacy/{bin,usr/{bin,sbin}} to the PATH while generating an mtree database for 'make release'. Note that the problem only exists here because mm-mtree.sh generates its own object tree to avoid mucking with the existing one, which results in a PATH containing legacy utility dirs that are empty.

The aim of this function is to eventually be the completion entry point for all 802.11 encapsulated mbufs. All the wifi drivers end up doing what is in this function so it's an easy win to turn it into a net80211 method and abstract out this code. Ideally the drivers will all eventually be modified to queue up completed mbufs and call this function with all the driver locks not held. This will allow for some much more interesting software queue handling in the future (like net80211 based A-MSDU, fast-frames, A-MPDU aggregation and retransmission.)

Use the two new union types (pam_conv_item_t and pam_text_item_t) to resolve strict aliasing violations caused by casts to comply with the pam_get_item() API taking a "const void **" for all item types. Warnings are generated for casts that create "type puns" (pointers of conflicting sized types that are set to access the same memory location) since these pointers may be used in ways that violate C's strict aliasing rules. Casts to a new type must be performed through a union in order to be compliant, and access must be performed through only one of the union's data types during the lifetime of the union instance. Handle strict-aliasing warnings through pointer assignments, which drastically simplifies this change. Correct a CLANG "printf-like function with more arguments than format" error.

We will poll every half second for a minute for the status to change. Hitachi drives (and likely other SAS drives) return that ASC/ASCQ when they are waiting to spin up. What it means is that they are waiting for the SAS expander to send them the SAS NOTIFY (ENABLE SPINUP) primitive. That primitive is the mechanism expanders/enclosures use to sequence drive spinup to avoid overloading power supplies.

CTASSERT's are provided to detect such issues at compile time in the future. The #define MLEN and MHLEN calculation do not take actual compiler- induced alignment and padding inside the complete struct mbuf into account. Accordingly appropriate attention is required when changing members of struct mbuf. Ideally one would calculate MLEN as (MSIZE - sizeof(((struct mbuf *)0)->m_hdr) but that doesn't work as the compiler refuses to operate on an as of yet incomplete structure. In particular ARM 32bit has more strict alignment requirements which caused 4 bytes of padding between m_hdr and pkthdr in struct mbuf because of the 64bit members in pkthdr. This wasn't picked up by MLEN and MHLEN causing an overflow of the mbuf provided data storage by overestimating its size. I386 didn't show this problem because it handles unaligned access just fine, albeit at a small performance penalty. On 64bit architectures the struct mbuf layout is 64bit aligned in all places.
