[Xen-devel] [PATCH v4 00/15] xenctx: Many changes.

[Don Slutz <dslutz@xxxxxxxxxxx>]

Add more functionality to xenctx.

Change from v3 to v4:
  Dropped patches:
    v3 #2 "xenctx: Correct check for xc_interface_open failing (prevents 
SIGSEGV)"
       Simular code already in master
    v3 #16 "MAINTAINERS: Add XENCTX maintainer"
       Way too soon for this.

  Most:  re-sytled all adds or changes to be in CODING_STYLE.

  #1 "xenctx: clean up usage output":
    Changed from kaddr to KADDR.

  Jan Beulich:
    v3 #4 "xenctx: Add -2 (--two-pages) option to switch stack size to 8KiB"
      Converted to
    #3 "xenctx: Add -m (--multiple_pages) option to output larger stack"

  #10 "xenctx: Add -M <maddr> option to dump memory at"
     Changed from -m to -M

  Added #15 "xenctx: Fix handling of !guest_protected_mode"

  Dropped forever:

  v1 patch #11 "xenctx: Dump registers via hvm info if available"

    This was a hack to work around a bug fix that is in 4.4.0


Change from v2 to v3:
  Added patches #1, #2, #5, and #16.
  v3 #1 "xenctx: clean up usage output":
      Move all usage cleanup into it's own patch/
  v3 #2 "xenctx: Correct check for xc_interface_open failing (prevents 
SIGSEGV)":
      Move xenctx.xc_handle out of patch v2 #9 ""
  v3 #5 "xenctx: Add command line options -b and -l":
      Redo to stack dump output size adjustments
      into commanle line options.
  v3 #16 "MAINTAINERS: Add XENCTX maintainer":
       Declare this I maintain xenctx, and drop George Dunlap.

  Unchanged (other then their number)
   v3 #3 "xenctx: Clean up stack trace when hypercall_page not in symbol table"
   v3 #8 "xenctx: Change print_symbol to do the space before."
   v3 #9 "xenctx: More info on failed to map page."

  Mostly from Jan Beulich:
  v3 #4 "xenctx: Add -2 (--two-pages) option to switch stack size to 8KiB":
    * Dropped extra change about i < 10.
    * Move add to usage to the end.
  v3 #6 "xenctx: Add command line option -D (--decode-as-ascii)":
  v3 #7 "xenctx: Add command line option -t (--tag-stack-dump)":
  v3 #10 "xenctx: Add command line option -T (--tag-call-trace)":
    * Add command line option to control this.
    * More info in commit message.
  v3 #11 "xenctx: Add -m <maddr> option to dump memory at maddr.":
    * Reworked option handling to allow multiple actions to work.
    * Add check for NO_TRANSLATION where needed.
    * Support -b and -l.
  v3 #12 "xenctx: Add -d <daddr> option to dump memory at daddr as a stack.":
    * Do this patch after -m patch.
    * Reworked option handling to allow multiple actions to work.
    * Add check for NO_TRANSLATION where needed.
    * More info in commit message.
  v3 #13 "xenctx: change is_kernel_text() into kernel_addr().":
    * new name is kernel_addr().
    * Use kernel_start if set.
    * Remove other changes.
  v3 #14 "xenctx: Add convert of more registers to symbols":
    * Extract just the symbol printing code from "xenctx: Dump registers via
      hvm info if available"
  v3 #15 "xenctx: Add output of vcpu value and state for --all-vcpus":
    * Extract just the vcpu printing code from "xenctx: xenctx: Add optional 
fCPU"

  v1 patch #11 "xenctx: Dump registers via hvm info if available" has 
     been defered to the "merge xenctx and xen_hvmctx" patch set.

  v1 patch #12 "xenctx: Add optional fCPU" has been dropped.

Change from v1 to v2:
  title was: xenctx: Add an option to output more registers.
  Processed review comments.
  Jan Beulich:
    Split 1 change into 12.
    Switch to enum for is_kernel_text(), renamed to is_kernel_addr().
    Renamed vars like memAddr to mem_addr.
  Ian Campbell:
    More on is_kernel_text().
