drm/via: Add new condition to via_dma_cleanup()

2022-09-07T05:01:16+00:00

Pointer dev_priv->mmio, which was checked for NULL at via_do_init_map(), is passed to via_do_cleanup_map() and is dereferenced there without check. The patch adds the condition in via_dma_cleanup() which prevents potential NULL pointer dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE.

drm/via: use idr_init_base() to initialize dev_priv->object_idr

2022-07-28T14:36:49+00:00

idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based IDRs more efficient"), let us set an arbitrary base other than idr_init(), which uses base 0. Since, for this IDR, no ID < 1 is ever requested/allocated, using idr_init_base(&idr, 1) avoids unnecessary tree walks.

drm/via: Fix style issues in via_3d_reg header

2022-07-16T07:32:20+00:00

- Fix comments using wrong style - Drop repeated word This fixes all checkpatch complains and makes the file a little bit easier to read - as the eye is not distracted by the style violations.

drm/via: Make macros readable in the via_3d_reg header

2022-07-16T07:32:13+00:00

The macros for texture 1 setting all used continuation on a new line, resulting in a highly ureadable definition. Merge the lines so they are each on a single line. As a nice side-effect this fixes a number of checkpatch warnings: "WARNING: please, no spaces at the start of a line".

drm/via: Use SPDX tag for MIT license in via_3d_reg header

2022-07-16T07:27:17+00:00

The license for the via_3d_reg header is MIT - so use the shorter SPDX tag to identify the license. Suggested-by: Thomas Zimmermann Signed-off-by: Sam Ravnborg Acked-by: Thomas Zimmermann Cc: Kevin Brace Link: https://patchwork.freedesktop.org/patch/msgid/20220713170202.1798216-12-sam@ravnborg.org

drm/via: Update to the latest via_3d_reg header

2022-07-16T07:27:11+00:00

Updated the 3d_reg header file to match what is used by the openchrome driver. This verifies that the two drivers can use the same header file. The file is a verbatim copy from the openchrome repo - a few style issues will be fixed in following commits.
