Ok. I have coded the AP rendezvous code and I simply cannot make
it give any sign of life. I'm now thinking that the IPI does
not reach the processor, even though the test IPI sent from the
BSP is received by the BSP.
Two questions:
1. I'm trying to insert a DTR of type PTE_MA_UC that covers the
processor interrupt block, but that's causing an exception:
fatal kernel trap:
trap vector = 0x18 (General Exception)
cr.iip = 0xe000000000880a70
cr.ipsr = 0x101008022010 (mfl,ic,dt,rt,cpl=0,it,ri=0,bn)
cr.isr = 0x8000000030 (ni,ei=0)
cr.ifa = 0xc0000000fee00000
cr.iim = 0xf4
curthread = 0xe000000000a5f8e0
pid = 0, comm =
Stopped at sapic_read+0x10: [MMI] st4.rel [r14]=r33;;
Does any of you know whether we need to have a mapping for the
PIB at all? (ie am I on the right track)?
2. We also don't have a mapping for the frame buffer (type PTE_MA_UC).
It looks to me that we need that as well. Is this right?
