Consult some concepts about shadow paging mechanism
Dear All: I am pretty new to xen-devel, please correct me in the following. Assume we have the following terms GPT: guest page table SPT: shadow page table (Question a) When guest OS is running, is it always using SPT for address translation? If it is the case, how does guest OS refer and modify its own GPT content? It seems that there is a page table entry in SPT for the GPT page. (Question

memory.profile() messes up the vector heap on Alpha/Linux?
....profile() > gc() As long as I don't execute memory.profile(), there is no problem with garbage collection. So I think that memory.profile() screws up the heap in some way. When it seg-faults, it dies in the function compactPhase() in memory.c, while (vfrom < R_VTop) { s = BACKPOINTER(*vfrom); switch (TYPEOF(s)) { /* get size in bytes */ /* <- dies here */ it segfaults becuase s becomes a pointer to 0x0, when the while loop is almost finishing, i.e., vfrom is close to R_VTop (vfrom = 0x20001840ef8 and R_VTop = 0x20001841198). I tried to see what's going on i...

[LLVMdev] whether these transformations are doable and how?
Thanks for all the replies which are really helpful. one more question regarding transformation: 4. Given an instruction %x1 = I1, can I replace the rhs "I1" with "I2" and get a new instruction %x1 = I2? Alternatively, I can add a new instruction %x2 = I2, and replace all uses of %x1 with %x2, and then delete %x1 = I1, but it seems the former is simpler or faster if

[PATCH 0/3] drm/connector: Provide generic support for underscan
Hello, This is an attempt at providing generic support for underscan connector props. We already have 3 drivers defining the same underscan, underscan vborder and underscan hborder properties (amd, radeon and nouveau) and I am about to add a new one, hence my proposal to put the prop parsing code in the core and add ->underscan fields to drm_connector_state. Note that I use this new
