2019-08-06drm/amdgpu: pin the csb buffer on hw init for gfx v8Likun Gao1-0/+40
Without this pin, the csb buffer will be filled with inconsistent data after S3 resume. And that will causes gfx hang on gfxoff exit since this csb will be executed then.

2019-08-06drm/amd/display: Block immediate flips for non-fast updatesNicholas Kazlauskas2-1/+16
[Why] Underflow can occur in the case where we change buffer pitch, DCC state, rotation or mirroring for a plane while also performing an immediate flip. It can also generate a p-state warning stack trace on DCN1 which is typically observed during the cursor handler pipe locking because of how frequent cursor updates can occur. [How] Store the update type on each CRTC - every plane will have access to the CRTC state if it's flipping. If the update type is not UPDATE_TYPE_FAST then the immediate flip should be disallowed. No changes to the target vblank sequencing need to be done, we just need to ensure that the surface registers do a double buffered update.

2019-08-06drm/amd/display: Validate dc_plane_info and dc_plane_size in atomic checkNicholas Kazlauskas1-0/+24
[Why] Pitch, DCC, rotation and mirroring can result in updates that are not UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info and dc_plane_size to make this determination and we aren't currently passing this into DC during atomic check. Underflow (visible or non-visible) can occur if we don't validate this correctly. This also will generally trigger p-state warnings, typically via the cursor handler when locking. [How] Get the framebuffer tiling flags and generate the required structures for DC in dm_determine_update_type_for_commit.

2019-08-06drm: Add Content protection type propertyRamalingam C7-3/+112
This patch adds a DRM ENUM property to the selected connectors. This property is used for mentioning the protected content's type from userspace to kernel HDCP authentication. Type of the stream is decided by the protected content providers. Type 0 content can be rendered on any HDCP protected display wires. But Type 1 content can be rendered only on HDCP2.2 protected paths. So when a userspace sets this property to Type 1 and starts the HDCP enable, kernel will honour it only if HDCP2.2 authentication is through for type 1. Else HDCP enable will be failed. Pekka have completed the Weston DRM-backend review in https://gitlab.freedesktop.org/wayland/weston/merge_requests/48 and the UAPI for HDCP 2.2 looks good.

2019-08-05tpm: tpm_ibm_vtpm: Fix unallocated banksNayna Jain4-17/+47
The nr_allocated_banks and allocated banks are initialized as part of tpm_chip_register. Currently, this is done as part of auto startup function. However, some drivers, like the ibm vtpm driver, do not run auto startup during initialization. This results in uninitialized memory issue and causes a kernel panic during boot. This patch moves the pcr allocation outside the auto startup function into tpm_chip_register. This ensures that allocated banks are initialized in any case.

2019-08-04kconfig: Clear "written" flag to avoid data lossM. Vefa Bicakci1-0/+4
Prior to this commit, starting nconfig, xconfig or gconfig, and saving the .config file more than once caused data loss, where a .config file that contained only comments would be written to disk starting from the second save operation. This bug manifests itself because the SYMBOL_WRITTEN flag is never cleared after the first call to conf_write, and subsequent calls to conf_write then skip all of the configuration symbols due to the SYMBOL_WRITTEN flag being set. This commit resolves this issue by clearing the SYMBOL_WRITTEN flag from all symbols before conf_write returns.
