config DRM_PANIC_SCREEN_QR_CODE
bool "Add a panic screen with a QR code"
depends on DRM_PANIC && RUST
help
This option adds a QR code generator, and a panic screen with a QR
code. The QR code will contain the last lines of kmsg and other debug
information. This should be easier for the user to report a kernel
panic, with all debug information available.
To use this panic screen, also set DRM_PANIC_SCREEN to "qr_code"
config DRM_PANIC_SCREEN_QR_CODE_URL
string "Base URL of the QR code in the panic screen"
depends on DRM_PANIC_SCREEN_QR_CODE
help
This option sets the base URL to report the kernel panic. If it's set
the QR code will contain the URL and the kmsg compressed with zlib as
a URL parameter. If it's empty, the QR code will contain the kmsg as
uncompressed text only.
There is a demo code in javascript, to decode and uncompress the kmsg
data from the URL parameter at https://github.com/kdj0c/panic_report

help
This option limits the version (or size) of the QR code. QR code
version ranges from Version 1 (21x21) to Version 40 (177x177).
Smaller QR code are easier to read, but will contain less debugging
data. Default is 40.

* 2) kmsg is zlib-compressed into buffer2
* 3) compressed kmsg is encoded as QR-code Numeric stream in buffer1
* 4) QR-code image is generated in buffer2

*
* Typically, ~7500 bytes of kmsg, are compressed into 2800 bytes, which fits in

*
* If CONFIG_DRM_PANIC_SCREEN_QR_CODE_URL is not set, the kmsg data will be put
