| // A valid gpu control list json file is in the format of |
| // { |
| // "version": "x.y", |
| // "entries": [ |
| // { // entry 1 |
| // }, |
| // ... |
| // { // entry n |
| // } |
| // ] |
| // } |
| // |
| // Each entry contains the following fields (fields are optional unless |
| // specifically described as mandatory below): |
| // 1. "id" is an integer. 0 is reserved. This field is mandatory. |
| // 2. "os" contains "type" and an optional "version". "type" could be "macosx", |
| // "linux", "win", "chromeos", or "any". "any" is the same as not specifying |
| // "os". |
| // "version" is a VERSION structure (defined below). |
| // 3. "vendor_id" is a string. 0 is reserved. |
| // 4. "device_id" is an array of strings. 0 is reserved |
| // 5. "device_revision" is an array of strings. Default is 0. This is Windows |
| // only. There are three ways to specify a device on Windows: |
| // a) only specify device IDs; |
| // b) specify one device ID, associate with multiple revisions; |
| // c) specify k device IDs, associate with k device revisions. |
| // https://docs.microsoft.com/en-us/windows-hardware/drivers/install/identifiers-for-pci-devices |
| // 6. "multi_gpu_style" is a string, valid values include: |
| // a) "optimus": NVIDIA dual GPU |
| // b) "amd_switchable": AMD dual GPU |
| // c) "amd_switchable_integrated": AMD dual GPU, integrated GPU is active |
| // d) "amd_switchable_discrete": AMD dual GPU, discrete GPU is active |
| // c) and d) are only valid on Win, as on Mac we can switch GPU on the fly. |
| // 7. "multi_gpu_category" is a string, valid values include "any", "primary", |
| // "secondary", and "active". If unspecified, the default value is "active". |
| // See gpu_control_list.h for more details on the meanings of the strings. |
| // 8. "driver_vendor" is a string pattern. (Not available on Windows) |
| // 9. "driver_version" is a VERSION structure (defined below). On Windows |
| // this value can be retrieved by searching for the "Driver File Version" in |
| // dxdiag.txt |
| // 10. "gl_type" is a string, valid values include "gl", "gles", and "angle". |
| // If "gl_version" is specified and "gl_type" is not, use the default value. |
| // The default value on Android is "gles", on Windows is "angle", on other |
| // platforms is "gl". |
| // 11. "gl_version" is a VERSION structure (defined below). |
| // 12. "gl_vendor" is a string pattern. |
| // 13. "gl_renderer" is a string pattern. |
| // 14. "gl_extensions" is a string pattern. |
| // 15. "machine_model_name" is an array of string patterns. |
| // 16. "machine_model_version" is a VERSION structure (defined below). |
| // 17. "gpu_count" is a INT structure (defined below). |
| // 18. "cpu_info" is a string pattern. |
| // 19. "exceptions" is a list of entries. |
| // 20. "features" is a list of gpu control list options, which can be |
| // configured by a specific list. See its *_json.cc file for a list of |
| // supported features. This field is mandatory. |
| // An "exceptions" list to the features can be added for convenience instead |
| // of listing all features except one. |
| // 21. "description" has the description of the entry. |
| // 22. "webkit_bugs" is an array of associated webkit bug numbers. |
| // 23. "cr_bugs" is an array of associated webkit bug numbers. |
| // 24. "disabled" is a boolean. If it is present, the entry will be skipped. |
| // This can not be used in exceptions. |
| // 25. "direct_rendering" is a boolean. If present, this will filter on whether |
| // the GL contexts are direct or indirect based on the value. |
| // 26. "disabled_extensions" is a list of strings which contain the GL_EXTENSION |
| // strings which are disabled by the workaround. |
| // 27. "pixel_shader_version" is a VERSION structure (defined below). |
| // 28. "test_group" is an non-negative integer. If not specified, it defaults |
| // to 0, which is Chrome's blocklist. Any entries with a non-zero test_group |
| // ID will be appended on top of the default group entries if Chrome runs |
| // with --gpu-blocklist-test-group=ID. |
| // 29. "intel_gpu_series" is a list of gpu series names. Currently supported |
| // series include: "broadwater", "eaglelake", "ironlake", "sandybridge", |
| // "baytrail", "ivybridge", "haswell", "cherrytrail", "broadwell", |
| // "apollolake", "skylake", "geminilake", "kabylake", "coffeelake", |
| // "whiskeylake", "cometlake", "cannonlake", "icelake", "elkhartlake", |
| // "jasperlake", "tigerlake", "alderlake". |
| // 30. "hardware_overlay" is either "supported" or "unsupported". Currently it |
| // only applies on Windows where hardware overlays may be supported on |
| // certain Intel GPUs. By default it's "dont_care" and there is no need to |
| // specify that. |
| // 31. "intel_gpu_generation" is a VERSION structure. Each Intel GPU has a |
| // specific integer (meaning generation) associated. |
| // 32. "subpixel_font_rendering" is either "supported" or "unsupported". |
| // Currently it only applies on ChromeOS where subpixel font rendering |
| // causes a glitch on Mali GPUs. By default it's "dont_care" and there is |
| // no need to specify that. |
| // 33. "driver_update_link" provides a link where affected users with older |
| // drivers can download a newer driver to avoid triggering this entry. |
| // Such link will be displayed in chrome://gpu for affected devices. |
| // |
| // VERSION includes "op", "style", "schema", "value", and "value2". "op" can |
| // be any of the following values: "=", "<", "<=", ">", ">=", "any", "between". |
| // "style" is optional and can be "lexical" or "numerical"; if it's not |
| // specified, it defaults to "numerical". "schema" is optional and can be |
| // "common", "intel_driver" or "nvidia_driver"; if it's not specified, it |
| // defaults to "common"; it's an error to specify "(intel|nvidia)_driver" schema |
| // for entries that are not specifically for Intel|Nvidia GPUs on Windows. |
| // "value2" is only used if "op" is "between". "between" is |
| // "value <= * <= value2". "value" is used for all "op" values except "any". |
| // "value" and "value2" are in the format of x, x.x, x.x.x, etc. |
| // Only "driver_version" supports lexical style if the format is major.minor; |
| // in that case, major is still numerical, but minor is lexical. |
| // Only "driver_version" supports "(intel|nvidia)_driver" schema. |
| // |
| // intel_driver schema versions have the form like "AA.BB.(CC|CCC).DDDD". The |
| // last two fields are most relevant, and the first two will be ignored by |
| // setting them to 0. Thus "0.0.(CC|CCC).DDDD" will be used in comparison |
| // following the general rule. |
| // |
| // FLOAT includes "op" "value", and "value2". "op" can be any of the |
| // following values: "=", "<", "<=", ">", ">=", "any", "between". "value2" is |
| // only used if "op" is "between". "value" is used for all "op" values except |
| // "any". "value" and "value2" are valid float numbers. |
| // INT is very much like FLOAT, except that the values need to be integers. |
