qemu-xen qdisk performance

[PATCH 0/8] RFC: ia64/xen TAKE 2: paravirtualization of hand written assembly code
Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

[LLVMdev] Register coalescer and reg_sequence (virtual super-regs)
...hat the virtual super reg interferes with sub reg instances, even though in reality they shouldn't conflict. That is, they are individual registers and would be better compared as such for register coalescing decisions (CoalescerPair::Partial = 0). For example, I have a super reg that has r20, r21, r22, and r23 physical registers. This super reg is the dest of a reg_sequence which generates 4 COPY MIs. The first COPY coalesces (merging into r20), but the vregs for r21-r23 (SUPER_RC:%vreg50:subreg1..subreg3) are never coalesced after that because doing so generates inteference on %vreg50, the...

[PATCH 0/4] ia64/xen: paravirtualization of hand written assembly code
Hi. The patch I send before was too large so that it was dropped from the maling list. I'm sending again with smaller size. This patch set is the xen paravirtualization of hand written assenbly code. And I expect that much clean up is necessary before merge. We really need the feed back before starting actual clean up as Eddie already said before. Eddie discussed how to clean up and suggested

...he register allocator to store 16 bit data in two contiguous 8 bit regs being the low part an even reg? Remember data would be expanded into 8 bit ops, so when we're working with dags after type legalization do we really know the original type before expansion? As an example, storing a short in r21:r20 would be valid, but r20:r19 or r20:r18 would be invalid because the in the first case the low reg is odd and in the second case regs arent contiguous. To store data wider than 16 bits, for example for a 32 bit int we would use 2 register pairs (4 8bit regs) but here the pairs dont need to be co...

Proper Usage of the XREG in ARIMA
...lar type of activity that week). Per the ARIMA instructions I am to feed those in a a vector or matrix. I am getting lost in the sand so to speak at this point. How would I prepare that data? I am pulling from a CSV that is roughly: date,usage,allocation,number of engines, theoretical max,r1,r2,...r21 So far so good just working with a copy of the CSV that is just date,usage But what should I do to disect the configuration data and the r1 to r21 dummy variables? (Some of these explain certain spikes and level shifts, forinstance r21 indicates if there was conversion activity during the week)....

[PATCH 00/15] ia64/pv_ops take 5
Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Now all the comments so far have been addressed, but only a few exceptions. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops strategy is appropriate too. Later I'll post the patchset which implements xen domU based on ia64/pv_ops.
