device_pager: user iterators to free device pages

2024-11-21T21:49:30Z

Change cdev_mgtdev_page_free_page to take an iterator, rather than an object and page, so that removing the page from the object radix tree can take advantage of locality with iterators. Define a general-purpose function to free all pages, which can be used in several places. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D47692

dev_pager: define free_page for mgt devices

2024-08-21T20:48:59Z

Callers of cdev_pager_free_page in the kernel always have object->type == OBJT_MGTDEVICE. Define a function for them to call that skips the runtime type check in cdev_pager_free. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D46389

gntdev: Handle errors from suword32() in gntdev_alloc_gref()

2023-12-26T02:04:01Z

Try to copy out output values before handling errors, and check that we did so successfully. In particular, it doesn't seem sensible to ignore errors here, otherwise userspace won't have any way to refer to the allocations. This is in preparation for annotating copyin() and related functions with __result_use_check. Reviewed by: royger MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D43145

Convert vm_page_alloc() callers to use vm_page_alloc_noobj().

2021-10-20T01:22:56Z

Remove page zeroing code from consumers and stop specifying VM_ALLOC_NOOBJ. In a few places, also convert an allocation loop to simply use VM_ALLOC_WAITOK. Similarly, convert vm_page_alloc_domain() callers. Note that callers are now responsible for assigning the pindex.

Convert allocations of the phys pager to vm_pager_allocate().

2020-09-08T23:38:49Z

Future changes would require additional initialization of OBJT_PHYS objects, and vm_object_allocate() is not suitable for it. Reviewed by: markj Tested by: pho Sponsored by: The FreeBSD Foundation MFC after: 1 week Differential revision: https://reviews.freebsd.org/D24652
