MFC r347892:LinuxKPI: Finalize import of seq_file.seq_file.h and linux_seq_file.c was imported form ports earlier butlinux_seq_file.c was never compiled in with the module.

46565964 - Augment wait queue support in the LinuxKPI.

Fri, 09 Jun 2017 19:41:12 +0000

Augment wait queue support in the LinuxKPI.In particular:- Don't evaluate event conditions with a sleepqueue lock held, since such code may attempt to acquire arbitrary locks.- Fix the return value for wait_event_interruptible() in the case that the wait is interrupted by a signal.- Implement wait_on_bit_timeout() and wait_on_atomic_t().- Implement some functions used to test for pending signals.- Implement a number of wait_event_*() variants and unify the existing implementations.- Unify the mechanism used by wait_event_*() and schedule() to put the calling thread to sleep.This is required to support updated DRM drivers. Thanks to hselasky forfinding and fixing a number of bugs in the original revision.Reviewed by: hselaskyMFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D10986 List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

14c5024d - Cleanup the LinuxKPI slab implementation.

Wed, 08 Mar 2017 11:09:27 +0000

Cleanup the LinuxKPI slab implementation.Put large functions into linux_slab.c instead of declaring them staticinline.Add support for more memory allocation wrappers like kmalloc_array()and __vmalloc().Make sure either the M_WAITOK or the M_NOWAIT flag is set and maskaway unused memory allocation flags before calling FreeBSD's malloc()routine.Move kmalloc_node() definition to slab.h where it belongs.Implement support for the SLAB_DESTROY_BY_RCU feature when creating akmem_cache which basically means kmem_cache memory is freed usingcall_rcu().MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

ca2ad6bd - LinuxKPI workqueue cleanup.

Tue, 07 Mar 2017 12:09:14 +0000

LinuxKPI workqueue cleanup.This change makes the workqueue implementation behave more like inLinux, both functionality wise and structure wise.All workqueue code has been moved to linux_work.cAdd an atomic based statemachine to the work_struct to ensure properoperation. Prior to this change struct_work was directly mapped to aFreeBSD task. When a taskqueue has multiple threads the same task mayend up being executed on more than one worker thread simultaneously.This might cause problems with code coming from Linux, which expectsserial behaviour, similar to Linux tasklets.Move all global workqueue function names into the linux_xxx domain toavoid symbol name clashes in the future.Implement a few more workqueue related functions and macros.Create two multithreaded taskqueues for the LinuxKPI during moduleload, one for time-consuming callbacks and one for non-time consumingcallbacks.MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

Wed, 22 Feb 2017 19:39:54 +0000

Optimise unmapped LinuxKPI page allocations.When allocating unmapped pages, take advantage of the direct map onAMD64 to get the virtual address corresponding to a page. Else allpages allocated must be mapped because sometimes the virtual addressof a page is requested.Move all page allocation and deallocation code into an own C-file.Add support for GFP_DMA32, GFP_KERNEL, GFP_ATOMIC and __GFP_ZEROallocation flags.Make a clear separation between mapped and unmapped allocations.Obtained from: kmacy @MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

ef23481a - Add support for LinuxKPI tasklets.

Tue, 21 Feb 2017 13:23:53 +0000

Add support for LinuxKPI tasklets.Tasklets are implemented using a taskqueue and a small statemachine ontop. The additional statemachine is required to ensure all LinuxKPItasklets get serialized. FreeBSD taskqueues do not guaranteeserialisation of its tasks, except when there is only one workerthread configured.MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

1e3db1de - Make the LinuxKPI task struct persistent accross system calls.

Tue, 21 Feb 2017 12:43:02 +0000

Make the LinuxKPI task struct persistent accross system calls.A set of helper functions have been added to manage the life of theLinuxKPI task struct. When an external system call or task is invoked,a check is made to create the task struct by demand. A threaddestructor callback is registered to free the task struct when athread exits to avoid memory leaks.This change lays the ground for emulating the Linux kernel moreclosely which is a dependency by the code using the LinuxKPI APIs.Add new dedicated td_lkpi_task field has been added to struct threadinstead of abusing td_retval[1].Fix some header file inclusions to make LINT kernel build properlyafter this change.Bump the __FreeBSD_version to force a rebuild of all kernel modules.MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile

8d59ecb2 - Finish process of moving the LinuxKPI module into the default kernel build.

Thu, 29 Oct 2015 08:28:39 +0000

Finish process of moving the LinuxKPI module into the default kernel build.- Move all files related to the LinuxKPI into sys/compat/linuxkpi and its subfolders.- Update sys/conf/files and some Makefiles to use new file locations.- Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn adds the LinuxKPI to all LINT builds.- The LinuxKPI can be added to the kernel by setting the COMPAT_LINUXKPI option. The OFED kernel option no longer builds the LinuxKPI into the kernel. This was done to keep the build rules for the LinuxKPI in sys/conf/files simple.- Extend the LinuxKPI module to include support for USB by moving the Linux USB compat from usb.ko to linuxkpi.ko.- Bump the FreeBSD_version.- A universe kernel build has been done.Reviewed by: np @ (cxgb and cxgbe related changes only)Sponsored by: Mellanox Technologies List of files: /freebsd-12.1/sys/modules/linuxkpi/Makefile
