The sparse array used for error decoding from is unnecessarily big. It should be better handled by a switch statement that will also allow us to more easily improve this code. Add a CASE_ERR() macro to keep the table compact and use it instead of the 256-entries array, which saves some space: $ bloat-o-meter xe_pcode.o.old xe_pcode.o add/remove: 0/1 grow/shrink: 2/0 up/down: 190/-4096 (-3906) Function old new delta __pcode_mailbox_rw 363 465 +102 __pcode_mailbox_rw.cold 58 146 +88 err_decode 4096 - -4096 Total: Before=7890, After=3984, chg -49.51% Reviewed-by: Raag Jadav <raag.jadav@intel.com> Link: https://patch.msgid.link/20251110-pcode-errmap-v2-1-cb18c8f54238@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
