* LinuxKPI: pci.h add more constantsBjoern A. Zeeb2023-11-291-0/+2
| | | | | | | | | Add two more PCI_EXP_LNKSTA_CLS constants to the compat defines needed by wireless drivers. Sponsored by: The FreeBSD Foundation (cherry picked from commit f74c09f3ec69a6cdba46aa821ab665d2f87142f7)
* LinuxKPI: implement get_random_u32_inclusive()Bjoern A. Zeeb2023-11-291-2/+28
| | | | | | | | | Implementation of get_random_u32_inclusive(). This is needed by an update for wireless drivers. Sponsored by: The FreeBSD Foundation (cherry picked from commit 1dcd1a539275fe69173bfc4dfc32c963fc7dcdbe)
* LinuxKPI: list.h add list_count_nodes()Bjoern A. Zeeb2023-11-291-0/+14
| | | | | | | | | Implement list_count_nodes() using a simple loop. This is needed by an updated wireless driver. Sponsored by: The FreeBSD Foundation (cherry picked from commit 1b18fb7faa75cc6dfa2e253190b41e63a997ca9d)
* LinuxKPI: cast jiffies_to_msecs() resultBjoern A. Zeeb2023-11-291-1/+1
| | | | | | | | | | jiffies_to_msecs() is expected to return an uint_t. In order to avoid changing printf format strings, properly cast the result to the expected type. Sponsored by: The FreeBSD Foundation (cherry picked from commit 08bc2cc4c4d8e94ad1db63f97d923dee18bee668)
* LinuxKPI: add DMA_MAPPING_ERRORBjoern A. Zeeb2023-11-291-1/+5
| | | | | | | While we deal with 0 returned, some drivers directly use and check for DMA_MAPPING_ERROR. Add the case and check for both in dma_mapping_error(). (cherry picked from commit 0b9bc97342f98a911985ace5527aef97863dfd23)

* linux(4): Uniformly dev_t arguments translationDmitry Chagin2023-06-294-33/+91
| | | | | | | | | | | | | | | | | | | | The two main uses of dev_t are in struct stat and as a parameter of the mknod system calls. As of version 2.6.0 of the Linux kernel, dev_t is a 32-bit quantity with 12 bits set asaid for the major number and 20 for the minor number. The in-kernel dev_t encoded as MMMmmmmm, where M is a hex digit of the major number and m is a hex digit of the minor number. The user-space dev_t encoded as mmmM MMmm, where M and m is the major and minor numbers accordingly. This is downward compatible with legacy systems where dev_t is 16 bits wide, encoded as MMmm. In glibc dev_t is a 64-bit quantity, with 32-bit major and minor numbers, encoded as MMMM Mmmm mmmM MMmm. This is downward compatible with the Linux kernel and with legacy systems where dev_t is 16 bits wide. In the FreeBSD dev_t is a 64-bit quantity. The major and minor numbers are encoded as MMMmmmMm, therefore conversion of the device numbers between Linux user-space and FreeBSD kernel required.
