   6 // A valid gpu_switching_list.json file are in the format of
   7 // {
   8 //   "version": "x.y",
   9 //   "entries": [
  10 //     { // entry 1
  11 //     },
  12 //     ...
  13 //     { // entry n
  14 //     }
  15 //   ]
  16 // }
  17 //
  18 // Each entry contains the following fields (fields are optional unless
  19 // specifically described as mandatory below):
  20 // 1. "id" is an integer.  0 is reserved.  This field is mandatory.
  21 // 2. "os" contains "type" and an optional "version". "type" could be "macosx",
  22 //    "linux", "win", "chromeos", or "any".  "any" is the same as not specifying
  23 //    "os".
  24 //    "version" is a VERSION structure (defined below).
  25 // 3. "vendor_id" is a string.  0 is reserved.
  26 // 4. "device_id" is an array of strings.  0 is reserved.
  27 // 5. "multi_gpu_style" is a string, valid values include "optimus", and
  28 //    "amd_switchable".
  29 // 6. "multi_gpu_category" is a string, valid values include "any", "primary",
  30 //    and "secondary".  If unspecified, the default value is "primary".
  31 // 7. "driver_vendor" is a STRING structure (defined below).
  32 // 8. "driver_version" is a VERSION structure (defined below).
  33 // 9. "driver_date" is a VERSION structure (defined below).
  34 //    The version is interpreted as "year.month.day".
  35 // 10. "gl_vendor" is a STRING structure (defined below).
  36 // 11. "gl_renderer" is a STRING structure (defined below).
  37 // 12. "gl_extensions" is a STRING structure (defined below).
  38 // 13. "perf_graphics" is a FLOAT structure (defined below).
  39 // 14. "perf_gaming" is a FLOAT structure (defined below).
  40 // 15. "perf_overall" is a FLOAT structure (defined below).
  41 // 16. "machine_model" contais "name" and an optional "version".  "name" is a
  42 //     STRING structure and "version" is a VERSION structure (defined below).
  43 // 17. "gpu_count" is a INT structure (defined below).
  44 // 18  "cpu_info" is a STRING structure (defined below).
  45 // 19. "exceptions" is a list of entries.
  46 // 20. "features" is a list of gpu switching options, including
  47 //     "force_discrete" and "force_integrated".
  48 //     This field is mandatory.
  49 // 21. "description" has the description of the entry.
  50 // 22. "webkit_bugs" is an array of associated webkit bug numbers.
  51 // 23. "cr_bugs" is an array of associated webkit bug numbers.
  52 // 24. "browser_version" is a VERSION structure (defined below).  If this
  53 //     condition is not satisfied, the entry will be ignored.  If it is not
  54 //     present, then the entry applies to all versions of the browser.
  55 // 25. "disabled" is a boolean. If it is present, the entry will be skipped.
  56 //     This can not be used in exceptions.
  57 //
  58 // VERSION includes "op", "style", "number", and "number2".  "op" can be any of
  59 // the following values: "=", "<", "<=", ">", ">=", "any", "between".  "style"
  60 // is optional and can be "lexical" or "numerical"; if it's not specified, it
  61 // defaults to "numerical".  "number2" is only used if "op" is "between".
  62 // "between" is "number <= * <= number2".
  63 // "number" is used for all "op" values except "any". "number" and "number2"
  64 // are in the format of x, x.x, x.x.x, etc.
  65 // Only "driver_version" supports lexical style if the format is major.minor;
  66 // in that case, major is still numerical, but minor is lexical.
  67 //
  68 // STRING includes "op" and "value".  "op" can be any of the following values:
  69 // "contains", "beginwith", "endwith", "=".  "value" is a string.
  70 //
  71 // FLOAT includes "op" "value", and "value2".  "op" can be any of the
  72 // following values: "=", "<", "<=", ">", ">=", "any", "between".  "value2" is
  73 // only used if "op" is "between".  "value" is used for all "op" values except
  74 // "any". "value" and "value2" are valid float numbers.
  75 // INT is very much like FLOAT, except that the values need to be integers.
