Ben Kunkle 1463b4d201 gpui/blade: Allow forcing use of a specific GPU with ZED_DEVICE_ID env var (#27531)
Workaround for users affected by #25899

Thanks to the work done by @kvark in
https://github.com/kvark/blade/pull/210, we have the ability to tell
Vulkan (through blade) a specific GPU to use.

This will hopefully allow some of the users affected by #25899 to use
Zed by allowing them to use a specific GPU, if the primary/default GPU
will not work

Release Notes:

- Added the ability to specify which GPU Zed uses on Linux by setting
the `ZED_DEVICE_ID` environment variable. You can obtain the device ID
of your GPU by running `lspci -nn | grep VGA` which will output each GPU
on one line like:
  ```
08:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA104
[GeForce RTX 3070] [10de:2484] (rev a1)
  ````
where the device ID here is `2484`. This value is in hexadecimal, so to
force Zed to use this specific GPU you would set the environment
variable like so:
  ```
  ZED_DEVICE_ID=0x2484
  ```
Make sure to export the variable if you choose to define it globally in
a `.bashrc` or similar

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
