The current algorithm to read out devcoredump is O(N*N) where N is the size of coredump due to usage of the drm_coredump_printer in xe_devcoredump_read. Switch to a O(N) algorithm which prints the devcoredump into a readable format in snapshot work and update xe_devcoredump_read to memcpy from the readable format directly. v2: - Fix double free on devcoredump removal (Testing) - Set read_data_size after snap work flush - Adjust remaining in iterator upon realloc (Testing) - Set read_data upon realloc (Testing) v3: - Kernel doc v4: - Two pass algorithm to determine size (Maarten) v5: - Use scope for reading variables (Johnathan) Reported-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/2408 Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240801154118.2547543-4-matthew.brost@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.
