* gone_in: make it __printflike()Gleb Smirnoff2025-06-241-10/+3
| | | | | | | | | | | | Provide flexibility to use format strings for gone_in(). As a side effect, this removes hardcoded string "Obsolete code will be removed soon:" from the message, so now it is obligation of the deprecated code to provide a meaningful message. This required a small adoption of the existing users: midi, drm2 and le(4). Note that gone_in() is not a public KPI as it has no sense to use it outside of the FreeBSD tree.

* log2: move log2 functions from linuxkpi to libkernDoug Moore2024-06-241-7/+0
| | | | | | | | | | | | | | | | | | | | | Linux has a header file that defines an ilog2 function and some simple functions/macros that use it: roundup_pow_of_two, is_power_of_2, rounddown_pow_of_two, and order_base_2. This change moves three of those simple functions (all but is_power_of_2) from linuxkpi to libkern. It also deletes a few implementations of these functions that have previously been copied into code for various device drivers, so that they can use the libkern version. The is_power_of_2 macro was not moved because powerof2 in param.h provides almost the same service already (except that they disagree about whether 0 is a power of two). Since the linux definitions of these functions were copied into FreeBSD 11 years ago, linux has improved them, and this change provides those improvements. In particular, a giant table of log values for evaluating ilog2 for constant values is no longer necessary.

* Avoid waiting on physical allocations that can't possibly be satisfiedJason A. Harmening2023-12-242-5/+8
| | | | | | | | | | | | | | | | | | | | | | | - Change vm_page_reclaim_contig[_domain] to return an errno instead of a boolean. 0 indicates a successful reclaim, ENOMEM indicates lack of available memory to reclaim, with any other error (currently only ERANGE) indicating that reclamation is impossible for the specified address range. Change all callers to only follow up with vm_page_wait* in the ENOMEM case. - Introduce vm_domainset_iter_ignore(), which marks the specified domain as unavailable for further use by the iterator. Use this function to ignore domains that can't possibly satisfy a physical allocation request. Since WAITOK allocations run the iterators repeatedly, this avoids the possibility of infinitely spinning in domain iteration if no available domain can satisfy the allocation request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc-based interface. Unfortunately, the glibc maintainers, despite knowing the existence of the FreeBSD qsort_r(3) interface in 2004 and refused to add the same interface to glibc based on grounds of the lack of standardization and portability concerns, has decided it was a good idea to introduce their own qsort_r(3) interface in 2007 as a GNU extension with a slightly different and incompatible interface. With the adoption of their interface as POSIX standard, let's switch to the same prototype, there is no need to remain incompatible. C++ and C applications written for the historical FreeBSD interface get source level compatibility when building in C++ mode, or when building with a C compiler with C11 generics support, provided that the caller passes a fifth parameter of qsort_r() that exactly matches the historical FreeBSD comparator function pointer type and does not redefine the historical qsort_r(3) prototype in their source code.

However, if multiple threads are opening a file, say, that causes the device to busy/unbusy, then we can race to the root marking things busy. Move to using a reference count to keep track of how many times a device_t has been made busy. Use that count to make the same decisions that we'd make with the old device state. Note: gpiopps.c uses D_TRACKCLOSE. Others do as well. However, there's a known race with closes that will be corrected for all the drivers that do this in a future commit.
