2020-11-05mm: introduce vma_set_file function v4Christian König1-3/+1
Add the new vma_set_file() function to allow changing vma->vm_file with the necessary refcount dance. v2: add more users of this. v3: add missing EXPORT_SYMBOL, rebase on mmap cleanup, add comments why we drop the reference on two occasions. v4: make it clear that changing an anonymous vma is illegal.

2020-11-05drm/msm: Drop struct_mutex in madvise pathRob Clark3-14/+3
The obj->lock is sufficient for what we need. This *does* have the implication that userspace can try to shoot themselves in the foot by racing madvise(DONTNEED) with submit. But the result will be about the same if they did madvise(DONTNEED) before the submit ioctl, ie. they might not get want they want if they race with shrinker. But iova fault handling is robust enough, so userspace is only shooting it's own foot. Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Kristian H.

2020-11-05drm/msm: Refcount submitsRob Clark4-12/+34
Before we remove dev->struct_mutex from the retire path, we have to deal with the situation of a submit retiring before the submit ioctl returns. To deal with this, ring->submits will hold a reference to the submit, which is dropped when the submit is retired. And the submit ioctl path holds it's own ref, which it drops when it is done with the submit. Also, add to submit list *after* getting/pinning bo's, to prevent badness in case the completed fence is corrupted, and retire_worker mistakenly believes the submit is done too early.

The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed. Let's start convert all the remaining helpers to provide a consistent interface, starting with the CRTC's atomic_check. The conversion was done using the coccinelle script below, built tested on all the drivers and actually tested on vc4. virtual report @@ struct drm_crtc_helper_funcs *FUNCS; struct drm_crtc *crtc; struct drm_crtc_state *crtc_state; identifier dev, state; identifier ret, f; @@ f(struct drm_device *dev, struct drm_atomic_state *state) { <... - ret = FUNCS->atomic_check(crtc, crtc_state); + ret = FUNCS->atomic_check(crtc, state); ...> } @@ identifier crtc, new_state; @@ struct drm_crtc_helper_funcs { ... - int (*atomic_check)(struct drm_crtc *crtc, struct drm_crtc_state *new_state); + int (*atomic_check)(struct drm_crtc *crtc, struct drm_atomic_state *state); ... } @ crtc_atomic_func @ identifier helpers; identifier func; @@ static struct drm_crtc_helper_funcs helpers = { ..., .atomic_check = func, ..., }; @ ignores_new_state @ identifier crtc_atomic_func.func; identifier crtc, new_state; @@ int func(struct drm_crtc *crtc, struct drm_crtc_state *new_state) { ... when != new_state } @ adds_new_state depends on crtc_atomic_func && !ignores_new_state @ identifier crtc_atomic_func.func; identifier crtc, new_state; @@ int func(struct drm_crtc *crtc, struct drm_crtc_state *new_state) { + struct drm_crtc_state *new_state = drm_atomic_get_new_crtc_state(state, crtc); ... } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; expression E; type T; @@ int func(...) { ... - T state = E; + T crtc_state = E; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; type T; @@ int func(...) { ... - T state; + T crtc_state; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; identifier new_state; identifier crtc; @@ int func(struct drm_crtc *crtc, - struct drm_crtc_state *new_state + struct drm_atomic_state *state ) { ... } @@ identifier new_state; identifier crtc; @@ int vmw_du_crtc_atomic_check(struct drm_crtc *crtc, - struct drm_crtc_state *new_state + struct drm_atomic_state *state ) { + struct drm_crtc_state *new_state = drm_atomic_get_new_crtc_state(state, crtc); ... } @@ identifier new_state; identifier crtc; @@ int vmw_du_crtc_atomic_check(struct drm_crtc *crtc, - struct drm_crtc_state *new_state + struct drm_atomic_state *state ); @ include depends on adds_new_state @ @@ #include <drm/drm_atomic.h> @ no_include depends on !include && adds_new_state @ @@ + #include <drm/drm_atomic.h> #include <drm/...> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20201028123222.1732139-1-maxime@cerno.tech

2020-11-01drm/msm: Unconditionally call dev_pm_opp_of_remove_table()Viresh Kumar3-16/+7
dev_pm_opp_of_remove_table() doesn't report any errors when it fails to find the OPP table with error -ENODEV (i.e. OPP table not present for the device). And we can call dev_pm_opp_of_remove_table() unconditionally here. While at it, also create a label to put clkname.
