MSI increases the number of interrupts that are possible. While conventional PCI was limited to four interrupts per card (and, because they were shared among all cards, most are using only one), message signalled interrupts allow dozens of interrupts per card, when that is useful. [1] There is also a slight performance advantage.
Interrupt service thread (IST) latencies are under 10 microseconds. Memory management – The deterministic memory pool allocated for RTX / RTX64 is taken from the system non-paged pool memory. For example, under Windows 7, the amount of non-paged pool is: for 32-bit, 1 GB to 2 GB of the random-access memory (RAM) depending on the configuration ...
IRQ 2/9 is the traditional interrupt line for an MPU-401 MIDI port, but this conflicts with the ACPI system control interrupt (SCI is hardwired to IRQ9 on Intel chipsets); [6] this means ISA MPU-401 cards with a hardwired IRQ 2/9, and MPU-401 device drivers with a hardcoded IRQ 2/9, cannot be used in interrupt-driven mode on a system with ACPI ...
This was chosen over edge-triggering to gain an advantage when servicing a shared interrupt line, and for robustness: edge-triggered interrupts are easy to miss. Later revisions of the PCI specification add support for message-signaled interrupts. In this system, a device signals its need for service by performing a memory write, rather than by ...
A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...

The Message Signaled Interrupts (MSI) feature of the PCI 2.2 and later specifications cannot be used without the local APIC being enabled. [8] Use of MSI obviates the need for an I/O APIC. Additionally, up to 224 interrupts are supported in MSI mode, and IRQ sharing is not allowed. [9]
INT 10h, INT 10H or INT 16 is shorthand for BIOS interrupt call 10 hex, the 17th interrupt vector in an x86-based computer system.The BIOS typically sets up a real mode interrupt handler at this vector that provides video services.
