...d/asid, hence, discard all previously used VPID tagged TLBs. In particular, consider a PV guest: write_ptbase -> write_cr3 -> hvm_flush_guest_tlbs -> hvm_asid_flush_core(). Since the PV guest is only using VPID 0 tagged TLBs, why do we need to flush all TLBs for all HVM guests? thanks Mukesh

....xen.org/ext/debuggers.hg/ has gotten outdated, I wasn''t sure if anyone was even looking at it. But, it looks like there is much interest, so I will just submit patch to Keir for his feedback on merging it in xen. Please voice your opinion here. Good seeing all at the summit :). Thanks, Mukesh

...why if (has_eflag(X86_EFLAGS_ID)) returns false in my HVM domU. Standard function has_eflag() in cpucheck.c running in real mode. Works fine on PV dom0, but fails when guest is booting on my hybrid dom0. LMK if any ideas. I''ll keep digging in the manuals, but nothing so far. thanks, Mukesh

For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored. The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

...is time_calibration_std_rendezvous() in c->stime_master_stamp. Chasing that, seems to come from read_platform_stime(). The jump happens after switch to xen clocksource in dom0. I''ll continue to debug, but let me know if you have any thoughts or idea what might be going on. thanks, Mukesh

Hi, kdb: to debug xen hypervisor, could also debug guests gdbsx: to debug PV/HVM linux guests The tree is : http://xenbits.xensource.com/ext/debuggers.hg See README-dbg. You''ll need to setup serial access for kdb. Thanks, Mukesh > > Hi Dan, > > I''m currently using your version of ssplitd as it is. I haven''t tried > kdb.

...g run. May be create a certain class of pages, that once migrated, are ''w'' protected, and any write faults on them are resolved on the target system, is one idea. Incidentally, IBM took the reverse approach. The (VCPU) contexts are migrated and pages are pulled in. thanks, Mukesh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

...he design on the fly here). I can create a new vcpuop saying the guest is using newer version. Or forget new version of shared_info{}, I can just put evtchn stuff in my own mfn and tell hypervisor to relocate it, (just like vcpu_info does) via new VCPUOP_ call. Keir, what do you think? thanks, Mukesh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

...nown and explored a lot by you as seen from your publications, but tuning LLVM with MPI(in particular OpenMPI) and other HPC requirement still needs to be explored. I think you will appreciate my initiative as a contributor to LLVM.

...MID_IO. Before the mfn is mapped, the l1 entry is not empty: 0000000139d08500: 00100001380a0027 After the mapping: 0000000139d08500: 00100000000a0467 as expected. However, the mfn 1380a0 still seems to belong to dom0. Shouldn''t that have been returned back to the xen heap? thanks, Mukesh

...pfn in dom0. Stefano, your concern was stuff mapped there causing problems in future. But we can always look at the e820 for conflicts. Keeping things fast is important for us . Please let me know if you still have issues with my approach. I believe this is what Ian is doing on ARM port. thanks, Mukesh

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );

hello all, At my workplace, our colleague Mukesh has just completed a port of speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions, but the trunk remains unchanged. It works quite well, I was wondering if there will be any interest in this port in the distribution. - farhan
