^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) This is a straight-forward UIO driver, where interrupts are disabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) by the interrupt handler and re-enabled via a write to the UIO device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) by the userspace-part.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) The only part that may seem odd is the use of a logical OR when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) storing and restoring enabled interrupts. This is done because the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) userspace-part could directly modify the Interrupt Enable Register
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) at any time. To reduce possible conflicts, the kernel driver uses
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) a logical OR to make more controlled changes (rather than blindly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) overwriting previous values).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Race conditions exist if the userspace-part directly modifies the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Interrupt Enable Register while in operation. The consequences are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) that certain interrupts would fail to be enabled or disabled. For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) this reason, the userspace-part should only directly modify the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) Interrupt Enable Register at the beginning (to get things going).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) The userspace-part can safely disable interrupts at any time using
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) a write to the UIO device.
