Add a small helper to determine if we have the panel power sequencer or not. We'll make PNV an exceptional case so that we can unset .is_mobile for the desktop variant. Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by:

g33/i964g/g45 are the exceptional cases when it comes to the swizzle detection. Let's reorder the code to handle them first and let everything else be handled by the else branch. This allows us to unset .is_mobile for the desktop PNV variant (which supposedly must follow the "mobile" path here). Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by:

Exercise acquiring and releasing forcewake around register reads. In order to read a register behind a GT powerwell, we need to instruct that powerwell to wake up using a forcewake. When we no longer require the GT powerwell, we tell the GT to release our forcewake. Inside the forcewake, the register read should work but outside it should just return garbage, 0 being the most common garbage. Thus we can detect when we are inside and outside of the forcewake with just a simple register read, and so can verify that the GT powerwell is released when we say so. v2: Picking the right forcewaked register to return 0 outside of forcewake is an art.

There is probably a issue in DMC firmwares(icl_dmc_ver1_07.bin and kbl_dmc_ver1_04.bin at least) that causes PSR2 SU to fail after exiting DC6 if EDP_PSR_TP1_TP3_SEL is kept in PSR_CTL, so for now lets workaround the issue by cleaning PSR_CTL before enable PSR2. v2: - Updated commit description and comment to state that it may be a DMC firmware issue (Rodrigo) - No need to RMW, let's write 0 to PSR_CTL(Dhinakaran) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

As the final request on a ring may hold the reference to this ring (via retiring the last pinned context), we may find ourselves chasing a dangling pointer on completion of the list. A quick solution is to hold a reference to the ring itself as we retire along it so that we only free it after we stop dereferencing it. Signed-off-by:

Slightly verbose, but does away with hand rolled shifts. Ties the field values with the mask defining the field. Unfortunately we have to make a local copy of FIELD_PREP() to evaluate to a integer constant expression. But with this, we can ensure the mask is non-zero, power of 2, fits u32, and the value fits the mask (when the value is a constant expression). Convert power sequencer registers as an example. v4: - rebase v3: - rename the macro to REG_FIELD_PREP to avoid underscore prefix and to be in line with kernel macros (Chris) - rename power of 2 check macro (Chris) v2: - add build-time checks with BUILD_BUG_ON_ZERO() - rename to just _FIELD() due to regmap.h REG_FIELD() clash Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

bitfield.h defines FIELD_GET() and FIELD_PREP() macros to access bitfields using the mask alone, with no need for separate shift. Indeed, the shift is redundant. We define REG_FIELD_GET() and REG_FIELD_PREP() wrappers for the above, in part to force u32 and for consistency with REG_BIT() and REG_GENMASK(), but also as we'll need to redefine REG_FIELD_PREP() in follow-up work to make it produce integer constant expressions. For the most part, REG_FIELD_GET() is shorter than masking followed by shift, and arguably has more clarity. REG_FIELD_PREP() can get more verbose than simply shifting in place, but it does provide masking to ensure we don't overflow the mask, something we usually don't bother with currently. Convert power sequencer registers as an example. v3: - temp variable removal (Chris) - rebase v2: - Add the REG_FIELD_GET() and REG_FIELD_PREP() wrappers to use them consistently from the start.

Introduce REG_BIT(n) to define register bits and REG_GENMASK(h, l) to define register bitfield masks. We define the above as wrappers to BIT() and GENMASK() respectively to force u32 type to go with our register size, and to add compile time checks on the bit numbers. The intention is that these are easier to get right and review against the spec than hand rolled masks. Convert power sequencer registers as an example. v4: - rebase v3: - rename macros to REG_BIT() and REG_GENMASK() to avoid underscore prefix and to be in line with kernel macros (Chris) - add compile time checks (Mika) v2: - rename macros to just _BIT() and _MASK() to reduce verbosity Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

We only need to acquire a wakeref for ourselves for a few operations, as most either already acquire their own wakeref or imply a wakeref. In particular, it is i915_gem_set_wedged() that needed us to present it with a wakeref, which is incongruous with its "use anywhere" ability. Suggested-by:

We assumed that vm_mmap() would reject an attempt to mmap past the end of the filp (our object), but we were wrong. Applications that tried to use the mmap beyond the end of the object would be greeted by a SIGBUS. After this patch, those applications will be told about the error on creating the mmap, rather than at a random moment on later access. Reported-by:
