2022-11-08drm/gem: Implement shadow-plane {begin, end}_fb_access with vmapThomas Zimmermann
Move the vmap code for shadow-plane helpers from prepare_fb to begin_fb_access helpers. Vunmap is now performed at the end of the current pageflip, instead of the end of the following pageflip. Reduces the duration of the mapping from while the framebuffer is being displayed to just the atomic commit. This is safe as outside of the pageflip, nothing should access the mapped buffer memory. Unmapping the framebuffer BO memory early allows to reduce address- space consumption and possibly allows for evicting the memory pages. The change is effectively a rename of prepare_fb and cleanup_fb implementations, plus updates to the shadow-plane init macro. As there's no longer a prepare_fb helper for shadow planes, atomic helpers will call drm_gem_plane_helper_prepare_fb() automatically. v2: * fix typos in commit message (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221025101737.8874-3-tzimmermann@suse.de
2022-11-08drm/atomic-helper: Add {begin,end}_fb_access to plane helpersThomas Zimmermann
Add {begin,end}_fb_access helpers to run at the beginning and end of an atomic commit. The begin_fb_access helper acquires resources that are necessary to perform the atomic commit. It it similar to prepare_fb, except that the resources are to be released at the end of the commit. Resources acquired by prepare_fb are held until after the next pageflip. The end_fb_access helper performs the corresponding resource cleanup. Atomic helpers call it with the new plane state. This is different from cleanup_fb, which releases resources of the old plane state. v2: * fix typos in commit message (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221025101737.8874-2-tzimmermann@suse.de

2022-11-05drm/fb-helper: Perform all fbdev I/O with the same implementationThomas Zimmermann
Implement the fbdev's read/write helpers with the same functions. Use the generic fbdev's code as template. Convert all drivers. DRM's fb helpers must implement regular I/O functionality in struct fb_ops and possibly perform a damage update. Handle all this in the same functions and convert drivers. The functionality has been used as part of the generic fbdev code for some time. The drivers don't set struct drm_fb_helper.fb_dirty, so they will not be affected by damage handling. For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and drm_fb_helper_cfb_write(). Several drivers require these. Until now tegra used I/O read and write, although the memory buffer appears to be in system memory. So use _sys_ helpers now. v3: * fix docs (Javier) v2: * rebase onto vmwgfx changes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221103151446.2638-18-tzimmermann@suse.de
2022-11-05drm/fb-helper: Disconnect damage worker from update logicThomas Zimmermann
The fbdev helpers implement a damage worker that forwards fbdev updates to the DRM driver. The worker's update logic depends on the generic fbdev emulation. Separate the two via function pointer. The generic fbdev emulation sets struct drm_fb_helper_funcs.fb_dirty, a new callback that hides the update logic from the damage worker. It's not possible to use the generic logic with other fbdev emulation, because it contains additional code for the shadow buffering that the generic emulation employs. DRM drivers with internal fbdev emulation can set fb_dirty to their own implementation if they require damage handling; although no such drivers currently exist.

2022-10-27drm/i915/perf: Apply Wa_18013179988Umesh Nerlige Ramappa
OA reports in the OA buffer contain an OA timestamp field that helps user calculate delta between 2 OA reports. The calculation relies on the CS timestamp frequency to convert the timestamp value to nanoseconds. The CS timestamp frequency is a function of the CTC_SHIFT value in RPM_CONFIG0. In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the actual value from RPM_CONFIG0. At the user level, this results in an error in calculating delta between 2 OA reports since the OA timestamp is not shifted in the same manner as CS timestamp. Also the periodicity of the reports is different from what the user configured because of mismatch in the CS and OA frequencies. The issue also affects MI_REPORT_PERF_COUNT command. To resolve this, return actual OA timestamp frequency to the user in i915_getparam_ioctl, so that user can calculate the right OA exponent as well as interpret the reports correctly.

Convert the EDID loader to struct drm_edid. There's a functional change in validation; it no longer tries to fix errors or filter invalid blocks. It's stricter in this sense.

2022-10-26drm/edid: detach debugfs EDID override from EDID property updateJani Nikula
Having the EDID override debugfs directly update the EDID property is problematic. The update is partial only. The driver has no way of knowing it's been updated. Mode list is not updated. It's an inconsistent state. Detach debugfs EDID override from the property update completely. Only set and reset a separate override EDID copy from debugfs, and have it take effect only at detect (via EDID read). The copy is at connector->edid_override, protected by connector->edid_override_mutex. This also brings override EDID closer to firmware EDID in behaviour.

2022-10-26drm/edid: rename drm_add_override_edid_modes() to ↵Jani Nikula
drm_edid_override_connector_update() Follow the naming of both EDID override functions as well as drm_edid_connector_update(). This also matches better what the function does; a combination of EDID property update and add modes. Indeed it should later be converted to call drm_edid_connector_update().

2022-10-23kernel/utsname_sysctl.c: Fix hostname pollingLinus Torvalds
Commit bfca3dd3d068 ("kernel/utsname_sysctl.c: print kernel arch") added a new entry to the uts_kern_table[] array, but didn't update the UTS_PROC_xyz enumerators of older entries, breaking anything that used them. Which is admittedly not many cases: it's really just the two uses of uts_proc_notify() in kernel/sys.c. But apparently journald-systemd actually uses this to detect hostname changes.

2022-10-21efi: efivars: Fix variable writes without query_variable_store()Ard Biesheuvel
Commit bbc6d2c6ef22 ("efi: vars: Switch to new wrapper layer") refactored the efivars layer so that the 'business logic' related to which UEFI variables affect the boot flow in which way could be moved out of it, and into the efivarfs driver. This inadvertently broke setting variables on firmware implementations that lack the QueryVariableInfo() boot service, because we no longer tolerate a EFI_UNSUPPORTED result from check_var_size() when calling efivar_entry_set_get_size(), which now ends up calling check_var_size() a second time inadvertently. If QueryVariableInfo() is missing, we support writes of up to 64k - let's move that logic into check_var_size(), and drop the redundant call.
