|

|

Sometimes you need to ensure that a subsequent call to :c:func:`xa_store`
|
||||
will not need to allocate memory. The :c:func:`xa_reserve` function
|
||||
will store a reserved entry at the indicated index. Users of the normal
|
||||
API will see this entry as containing ``NULL``. If you do not need to
|
||||
use the reserved entry, you can call :c:func:`xa_release` to remove the
|
||||
unused entry. If another user has stored to the entry in the meantime,
|
||||
:c:func:`xa_release` will do nothing; if instead you want the entry to
|
||||
become ``NULL``, you should use :c:func:`xa_erase`.
|
||||
|
||||
If all entries in the array are ``NULL``, the :c:func:`xa_empty` function
|
||||
will return ``true``.
|
||||
|
||||
Finally, you can remove all entries from an XArray by calling
|
||||
:c:func:`xa_destroy`. If the XArray entries are pointers, you may wish
|

to free the entries first. You can do this by iterating over all present

Allocating XArrays
|
||||
------------------
|
||||
|
||||
If you use :c:func:`DEFINE_XARRAY_ALLOC` to define the XArray, or
|
||||
initialise it by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
|
||||
the XArray changes to track whether entries are in use or not.
|
||||
|
||||
You can call :c:func:`xa_alloc` to store the entry at any unused index
|
||||
in the XArray. If you need to modify the array from interrupt context,
|
||||
you can use :c:func:`xa_alloc_bh` or :c:func:`xa_alloc_irq` to disable
|
||||
interrupts while allocating the ID. Unlike :c:func:`xa_store`, allocating
|
||||
a ``NULL`` pointer does not delete an entry. Instead it reserves an
|
||||
entry like :c:func:`xa_reserve` and you can release it using either
|
||||
:c:func:`xa_erase` or :c:func:`xa_release`. To use ID assignment, the
|
||||
XArray must be defined with :c:func:`DEFINE_XARRAY_ALLOC`, or initialised
|
||||
by passing ``XA_FLAGS_ALLOC`` to :c:func:`xa_init_flags`,
|
||||
interrupts while allocating the ID.
|
||||
|
||||
Using :c:func:`xa_store`, :c:func:`xa_cmpxchg` or :c:func:`xa_insert`
|
||||
will mark the entry as being allocated. Unlike a normal XArray, storing
|
||||
``NULL`` will mark the entry as being in use, like :c:func:`xa_reserve`.
|
||||
To free an entry, use :c:func:`xa_erase` (or :c:func:`xa_release` if
|
||||
you only want to free the entry if it's ``NULL``).
|
||||
|
||||
You cannot use ``XA_MARK_0`` with an allocating XArray as this mark
|
||||
is used to track whether an entry is free or not. The other marks are
|
||||
available for your use.

drm/amd/display - Display Core (DC)
|
||||
===================================
|
||||
|
||||
*placeholder - general description of supported platforms, what dc is, etc.*
|
||||
|
||||
Because it is partially shared with other operating systems, the Display Core
|
||||
Driver is divided in two pieces.
|
||||
|
||||
1. **Display Core (DC)** contains the OS-agnostic components. Things like
|
||||
hardware programming and resource management are handled here.
|
||||
2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
|
||||
amdgpu base driver and DRM are implemented here.
|
||||
|
||||
It doesn't help that the entire package is frequently referred to as DC. But
|
||||
with the context in mind, it should be clear.
|
||||
|
||||
When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
|
||||
supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
|
||||
Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
|
||||
|
||||
To determine if DC is loaded, search dmesg for the following entry:
|
||||
|
||||
``Display Core initialized with <version number here>``

Description
|

-----------
|
||||
|
||||
i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
|
||||
and later GPUs and it is used to communicate with Type-C controller on GPUs.
|
||||
|
||||
If your 'lspci -v' listing shows something like the following,

||||
01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
|
||||
|
||||
then this driver should support the I2C controller of your GPU.
