From: Sylvain Gault <sylvain.gault at gmail.com> On some architecture, including my hardware, the function ExitBootServices may need to be called twice in order to successfully exit the boot services. As stated by the UEFI spec, the first call to ExitBootServices may perform a partial shutdown of the services. It seems that during this partial shutdown, the memory map can be modified, thus

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

This just defines the namespace, its contexts and related constants and the only supported one is currently base:allocation. The names of the constants are not very future-proof, but shorter than LIBNBD_META_NS_CONTEXT_BASE_ALLOCATION or similar. Currently the output looks like this: /* "base" namespace */ /* "base" namespace contexts */ /* "base:allocation"

The power sensors can be configured to sample the readout values over time. Nvidia does this too, so nouveau should probably do that too.
