[Intel-gfx] [PATCH v2 2/2] drm/i915: Introduce intel_reg_types.h

Daniele Ceraolo Spurio daniele.ceraolospurio at intel.com
Tue Aug 20 02:01:47 UTC 2019


With the introduction of display uncore, we want to categorize registers
between display and non-display. To help us getting it right, it will
be useful to move the display registers to a new file that can be used
without including i915_reg.h. To allow that, move all the basic register
type definitions and helpers to intel_reg_types.h and include that
instead of i915_reg.h from header files in the driver. We'll then
be able to replace i915_reg.h with the new display-only header in
display files and make sure the registers are correctly
compartmentalized.

While at it, rename i915_reg.h to intel_reg.h to better indicate that it
contains HW defs.

v2: use intel_* prefix for register files (Michal)

-/**
- * DOC: The i915 register macro definition style guide
- *
- * Follow the style described here for new macros, and while changing existing
- * macros. Do **not** mass change existing definitions just to update the style.
- *
- * Layout
- * ~~~~~~
- *
- * Keep helper macros near the top. For example, _PIPE() and friends.
- *
- * Prefix macros that generally should not be used outside of this file with
- * underscore '_'. For example, _PIPE() and friends, single instances of
- * registers that are defined solely for the use by function-like macros.
- *
- * Avoid using the underscore prefixed macros outside of this file. There are
- * exceptions, but keep them to a minimum.
- *
- * There are two basic types of register definitions: Single registers and
- * register groups. Register groups are registers which have two or more
- * instances, for example one per pipe, port, transcoder, etc. Register groups
- * should be defined using function-like macros.
- *
- * For single registers, define the register offset first, followed by register
- * contents.
- *
- * For register groups, define the register instance offsets first, prefixed
- * with underscore, followed by a function-like macro choosing the right
- * instance based on the parameter, followed by register contents.
- *
- * Define the register contents (i.e. bit and bit field macros) from most
- * significant to least significant bit. Indent the register content macros
- * using two extra spaces between ``#define`` and the macro name.
- *
- * Define bit fields using ``REG_GENMASK(h, l)``. Define bit field contents
- * using ``REG_FIELD_PREP(mask, value)``. This will define the values already
- * shifted in place, so they can be directly OR'd together. For convenience,
- * function-like macros may be used to define bit fields, but do note that the
- * macros may be needed to read as well as write the register contents.
- *
- * Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
- *
- * Group the register and its contents together without blank lines, separate
- * from other registers and their contents with one blank line.
- *
- * Indent macro values from macro names using TABs. Align values vertically. Use
- * braces in macro values as needed to avoid unintended precedence after macro
- * substitution. Use spaces in macro values according to kernel coding
- * style. Use lower case in hexadecimal values.
- *
- * Naming
- * ~~~~~~
- *
- * Try to name registers according to the specs. If the register name changes in
- * the specs from platform to another, stick to the original name.
- *
- * Try to re-use existing register macro definitions. Only add new macros for
- * new register offsets, or when the register contents have changed enough to
- * warrant a full redefinition.
- *
- * When a register macro changes for a new platform, prefix the new macro using
- * the platform acronym or generation. For example, ``SKL_`` or ``GEN8_``. The
- * prefix signifies the start platform/generation using the register.
- *
- * When a bit (field) macro changes or gets added for a new platform, while
- * retaining the existing register macro, add a platform acronym or generation
- * suffix to the name. For example, ``_SKL`` or ``_GEN8``.
- *
- * Examples
- * ~~~~~~~~
- *
- * (Note that the values in the example are indented using spaces instead of
- * TABs to avoid misalignment in generated documentation. Use TABs in the
- * definitions.)::
- *
- *  #define _FOO_A                      0xf000
