drm: Remove the obsolete driver-sis

2023-01-13T08:44:43+00:00

Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked sis driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Silicon Integrated Systems->drivers/gpu/drm/sis

It's time to remove this driver.

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

2022-07-28T14:35:56+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.

Drop use of the deprecated drmP.h header.
Repalced with relevant header files and sorted header files in all files
touched.

Replaced DRM_{READ,WRITE} to avoid the drm_os_linux header.

Build tested with allyesconfig, allmodconfig on various architectures.

drm/pci: Deprecate drm_pci_init/exit completely

2017-06-20T08:41:03+00:00

The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

The only special-case is pci devices, and we can easily handle this in
the core. Do so and drop a pile of boilerplate from drivers.

drm: Improve drm_mm search (and fix topdown allocation) with rbtrees

2017-02-03T10:10:32+00:00

The drm_mm range manager claimed to support top-down insertion, but it
was neither searching for the top-most hole that could fit the
allocation request nor fitting the request to the hole correctly.

In order to search the range efficiently, we create a secondary index
for the holes using either their size or their address. This index
allows us to find the smallest hole or the hole at the bottom or top of
the range efficiently, whilst keeping the hole stack to rapidly service
evictions.

v2: Search for holes both high and low. Rename flags to mode.
v3: Discover rb_entry_safe() and use it!
v4: Kerneldoc for enum drm_mm_insert_mode.
