Subject: [PATCH v3 00/12] plugins/execlog: add data address match and address range support
Date: Fri,  1 Mar 2024 18:45:57 +0100	[thread overview]
Message-ID: <20240301174609.1964379-1-svens@stackframe.org> (raw)

Hi List,

this patchset adds a new -dfilter option and address range matching. With this
execlog can match only a certain range of address for both instruction and
data adresses.

Example usage:

qemu-system-xxx <other options> -d plugin -plugin libexeclog.so,afilter=0x1000-0x2000,dfilter=0x388

This would only log instruction in the address range 0x1000 to 0x2000
and accessing data at address 0x388.

Changes in v3:
- extend plugin api to re-use the existing range parsing infrastructure
- export error report api

Changes in v2:
- rebased on top of latest master

Sven Schnelle (12):
  util/log: convert debug_regions to GList
  util/log: make qemu_set_dfilter_ranges() take a GList
  util/range: move range_list_from_string() to range.c
  util/range: add range_list_free()
  util/range: use append_new_range() in range_list_from_string()
  util/range: split up range_list_from_string()
  util/range: make range_list_from_string() accept a single number
  qemu/range: add range_list_contains() function
  plugins: add API to print errors
  plugins: add range list API
  plugins/execlog: use range list api
  plugins/execlog: add data address match
