This action sets ASMI[n+1] high again and causes another CS5535 ASMI. 9) VSA begins to return to the process interrupted by the original ASMI, but notes SMI into the processor is still asserted and returns to step 3. 10) If there was no Event[Y] at any point above, return to the interrupted process. Note: Step 5 above could occur at any time between step 2 and step 9, or the Event[Y] could come after step 10. Regardless, the same VSA approach is used in order not to miss any events. 3.8.3.2 Apparent SSMI An SSMI event is associated with an I/O space access to a specific address or range of addresses. If SSMIs are enabled for the given address, then the hardware traps or blocks access to the target register. The actual register write and/or read operation is not performed. Generally, only write operations are trapped, but there are cases of trapping writes and reads. The CS5535 does not support SSMIs, however, the CS5535 supports a mechanism called “Apparent SSMI” using ASMIs. (Hereafter “Apparent SSMI” is referred to as “SSMI”.) The CS5535 insures that the ASMI is taken on the I/O instruction boundary. The ASMI reaches the CPU before a target ready is signaled on the PCI bus. This action creates an SSMI because the I/O instruction will not complete before ASMI reaches the CPU. VSA software then exam- ines the GLPCI_SB GLD_SMI_MSR to determine if an SSMI has occurred from an I/O trap. Figure 3-8.
