# Declarations

## <desc>
## <p>
## Allow chromium to access direct rendering interface
## </p>
## <p>
## Needed for good performance on complex sites
## </p>
## </desc>
gen_tunable(chromium_dri, true)
## <desc>
## <p>
## Allow chromium to read system information
## </p>
## <p>
## Although not needed for regular browsing, this will allow chromium to update
## its own memory consumption based on system state, support additional
## debugging, detect specific devices, etc.
## </p>
## </desc>
gen_tunable(chromium_read_system_info, false)
## <desc>
## <p>
## Allow chromium to bind to tcp ports
## </p>
## <p>
## Although not needed for regular browsing, some chrome extensions need to
## bind to tcp ports and accept connections.
## </p>
## </desc>
gen_tunable(chromium_bind_tcp_unreserved_ports, false)
## <desc>
## <p>
## Allow chromium to read/write USB devices
## </p>
## <p>
## Although not needed for regular browsing, used for debugging over usb
## or using FIDO U2F tokens.
## </p>
