| | | | | | | | | | | | | For drmkpi (D23085) we don't want the Linux struct file as we don't emulate everything. Also the prototypes should be in shmem_fs.h to have 100% compatibility with Linux.

* LinuxKPI: Finalize import of seq_file.Johannes Lundberg2019-05-161-0/+1
| | | | | | | | | | | | | | seq_file.h and linux_seq_file.c was imported form ports earlier but linux_seq_file.c was never compiled in with the module. With this commit base seq_file will replace ports seq_file and it required a few modifications to not break functionality and build.

* Augment wait queue support in the LinuxKPI.Mark Johnston2017-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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 for finding and fixing a number of bugs in the original revision.

* Cleanup the LinuxKPI slab implementation.Hans Petter Selasky2017-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Put large functions into linux_slab.c instead of declaring them static inline. 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 mask away 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 a kmem_cache which basically means kmem_cache memory is freed using call_rcu().

* LinuxKPI workqueue cleanup.Hans Petter Selasky2017-03-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes the workqueue implementation behave more like in Linux, both functionality wise and structure wise. All workqueue code has been moved to linux_work.c Add an atomic based statemachine to the work_struct to ensure proper operation. Prior to this change struct_work was directly mapped to a FreeBSD task. When a taskqueue has multiple threads the same task may end up being executed on more than one worker thread simultaneously. This might cause problems with code coming from Linux, which expects serial behaviour, similar to Linux tasklets. Move all global workqueue function names into the linux_xxx domain to avoid symbol name clashes in the future. Implement a few more workqueue related functions and macros. Create two multithreaded taskqueues for the LinuxKPI during module load, one for time-consuming callbacks and one for non-time consuming callbacks.

* Optimise unmapped LinuxKPI page allocations.Hans Petter Selasky2017-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | | When allocating unmapped pages, take advantage of the direct map on AMD64 to get the virtual address corresponding to a page. Else all pages allocated must be mapped because sometimes the virtual address of 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_ZERO allocation flags. Make a clear separation between mapped and unmapped allocations.

* Add support for LinuxKPI tasklets.Hans Petter Selasky2017-02-211-0/+1
| | | | | | | | | | | | | | Tasklets are implemented using a taskqueue and a small statemachine on top. The additional statemachine is required to ensure all LinuxKPI tasklets get serialized. FreeBSD taskqueues do not guarantee serialisation of its tasks, except when there is only one worker thread configured.

* Make the LinuxKPI task struct persistent accross system calls.Hans Petter Selasky2017-02-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | A set of helper functions have been added to manage the life of the LinuxKPI task struct. When an external system call or task is invoked, a check is made to create the task struct by demand. A thread destructor callback is registered to free the task struct when a thread exits to avoid memory leaks. This change lays the ground for emulating the Linux kernel more closely which is a dependency by the code using the LinuxKPI APIs. Add new dedicated td_lkpi_task field has been added to struct thread instead of abusing td_retval[1]. Fix some header file inclusions to make LINT kernel build properly after this change. Bump the __FreeBSD_version to force a rebuild of all kernel modules. MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=314040
* Finish process of moving the LinuxKPI module into the default kernel build.Hans Petter Selasky2015-10-291-4/+7
| | | | | | | | | | | | | | | | | | | | | | - 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.
