      drm/i915: Add release id version · ca6374e2
      由 Lucas De Marchi 提交于 
      Besides the arch version returned by GRAPHICS_VER(), new platforms
contain a "release id" to make clear the difference from one platform to
another.

The release id number is not formally defined by hardware until future
platforms that will expose it via a new GMD_ID register.  For the
platforms we support before that register becomes available we will set
the values in software and we can set them as we please. So the plan is
to set them so we can group different features under a single
GRAPHICS_VER_FULL() check.

After GMD_ID is used, the usefulness of a "full version check" will be
greatly reduced and will be mostly used for deciding workarounds and a
few code paths. So it makes sense to keep it as a separate field from
graphics_ver. Also, as a platform with `release == n` may be closer
feature-wise to `n - 2` than to `n - 1`, use the word "release" rather
than the more common "minor" for this

This is a mix of 2 independent changes: one by me and the other by Matt
Roper.

v2:
  - Reword commit message to make it clearer why we don't call it
    "minor" (Matt Roper and Tvrtko)
  - Rename variables s/*_ver_release/*_rel/ and print them in a single
    line formatted as {ver}.{rel:2} (Jani and Matt Roper)

      drm/i915: Add DISPLAY_VER() and related macros · 01eb15c9
      由 Matt Roper 提交于 
      Although we've long referred to platforms by a single "GEN" number, the
hardware teams have recommended that we stop doing this since the
various component IP blocks are going to start using independent number
schemes with varying cadence.  To support this, hardware platforms a bit
down the road are going to start providing MMIO registers that the
driver can read to obtain the "graphics version," "media version," and
"display version" without needing to do a PCI ID -> platform -> version
translation.

Although our current platforms don't yet expose these registers (and the
next couple we release probably won't have them yet either), the
hardware teams would still like to see us move to this independent
numbering scheme now in preparation.  For i915 that means we should try
to eliminate all usage of INTEL_GEN() throughout our code and instead
replace it with separate GRAPHICS_VER(), MEDIA_VER(), and DISPLAY_VER()
constructs in the code.  For old platforms, these will all usually give
the same value for each IP block (aside from a few special cases like
GLK which we can no more accurately represent as graphics=9 +
display=10), but future platforms will have more flexibility to bump IP
version numbers independently.

The upcoming ADL-P platform will have a display version of 13 and a
graphics version of 12, so let's just the first step of breaking out
DISPLAY_VER(), but leaving the rest of INTEL_GEN() untouched for now.
For now we'll automatically derive the display version from the
platform's INTEL_GEN() value except in cases where an alternative
display version is explicitly provided in the device info structure.

We also add some helper macros IS_DISPLAY_VER(i915, ver) and
IS_DISPLAY_RANGE(i915, from, until) that match the behavior of the
existing gen-based macros.  However unlike IS_GEN(), we will implement
those macros with direct comparisons rather than trying to maintain a
mask to help compiler optimization.  In practice the optimization winds
up not being used in very many places (since the vast majority of our
platform checks are of the form "gen >= x") so there is pretty minimal
size reduction in the final driver binary[1].  We're also likely going
to need to extend these version numbers to non-integer major.minor
values at some point in the future, so the mask approach won't work at
all once we get to platforms like that.

 [1] The results before/after the next patch in this series, which
     switches our code over to the new display macros:

        $ size i915.ko.{orig,new}
           text    data     bss     dec     hex filename
        2940291  102944    5384 3048619  2e84ab i915.ko.orig
        2940723  102956    5384 3049063  2e8667 i915.ko.new

v2:
 - Move version into device info's display sub-struct. (Jani)
 - Add extra parentheses to macros.  (Jani)
 - Note the lack of genmask optimization in the display-based macros and
   give size data.  (Lucas)

      drm/i915: FPGA_DBG is display-specific · a321c3c6
      由 Matt Roper 提交于 
      Although the bspec's description doesn't make it very clear, the
hardware architects have confirmed that the FPGA_DBG register that we
use to check for unclaimed MMIO accesses is display-specific and will
only properly flag unclaimed MMIO transactions for registers in the
display range.  If a platform doesn't have display, FPGA_DBG itself will
not be available and should not be checked.  Let's move the feature flag
into intel_device_info.display to more accurately reflect this.

Given that we now know FPGA_DBG is display-specific, it could be argued
that we should only check it on out intel_de_*() functions.  However
let's not make that change right now; keeping the checks in all of the
existing locations still helps us catch cases where regular
intel_uncore_*() functions use bad MMIO offset math / base addresses and
accidentally wind up landing within an unused area within the display
MMIO range.  It will also help catch cases where userspace-initiated
MMIO (e.g., IGT's intel_reg tool) attempt to read bad offsets within the
display range.

v2:  Add missing hunk with the update to the HAS_FPGA_DBG_UNCLAIMED
     macro.  (CI)
