2022-05-02drm/msm/dpu: Issue MDSS reset during initializationBjorn Andersson1-0/+32
It's typical for the bootloader to bring up the display for showing a boot splash or efi framebuffer. But in some cases the kernel driver ends up only partially configuring (in particular) the DPU, which might result in e.g. that two different data paths attempts to push data to the interface - with resulting graphical artifacts. Naturally the end goal would be to inherit the bootloader's configuration and provide the user with a glitch free handover from the boot configuration to a running DPU. But as implementing seamless transition from the bootloader configuration to the running OS will be a considerable effort, start by simply resetting the entire MDSS to its power-on state, to avoid the partial configuration.

2022-05-02drm/msm/dpu: Bind pingpong block to intf on active ctls in cmd encoderMarijn Suijten1-0/+19
As per the specification of DPU_CTL_ACTIVE_CFG the configuration of active blocks should be proactively specified, and the pingpong block is no different. The downstream display driver [1] confirms this by also calling bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always entered, as setup_intf_cfg - unlike this mainline dpu driver that combines both behind the same function pointer - is left NULL in favour of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set. This solves continuous timeouts on at least the Qualcomm sm6125 SoC: [drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout [drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1 [drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0 In the same way this pingpong block should also be unbound followed by an interface flush when the encoder is disabled, according to the downstream display driver [2].

2022-05-01x86/apic: Do apic driver probe for "nosmp" use caseKuppuswamy Sathyanarayanan1-3/+2
For the "nosmp" use case, the APIC initialization code selects "APIC_SYMMETRIC_IO_NO_ROUTING" as the default interrupt mode and avoids probing APIC drivers. This works well for the default APIC modes, but for the x2APIC case the probe function is required to allocate the cluster_hotplug mask. So in the APIC_SYMMETRIC_IO_NO_ROUTING case when the x2APIC is initialized it dereferences a NULL pointer and the kernel crashes. This was observed on a TDX platform where x2APIC is enabled and "nosmp" command line option is allowed. To fix this issue, probe APIC drivers via default_setup_apic_routing() for the APIC_SYMMETRIC_IO_NO_ROUTING interrupt mode too. Suggested-by: Kirill A.

Define a function named fsverity_get_digest() to return the verity file digest and the associated hash algorithm (enum hash_algo). This assumes that before calling fsverity_get_digest() the file must have been opened, which is even true for the IMA measure/appraise on file open policy rule use case (func=FILE_CHECK). do_open() calls vfs_open() immediately prior to ima_file_check().

2022-05-01ima: use IMA default hash algorithm for integrity violationsMimi Zohar1-1/+1
Integrity file violations - ToM/ToU, open writers - are recorded in the IMA measurement list, containing 0x00's in both the template data and file data hash fields, but 0xFF's are actually extended into TPM PCRs. Although the original 'ima' template data field ('d') is limited to 20 bytes, the 'd-ng' template digest field is not. The violation file data hash template field ('d-ng') is unnecessarily hard coded to SHA1. Instead of simply replacing the hard coded SHA1 hash algorithm with a larger hash algorithm, use the hash algorithm as defined in "ima_hash_algo". ima_hash_algo is set to either the Kconfig IMA default hash algorithm or as defined on the boot command line (ima_hash=). Including a non-SHA1 file data hash algorithm in the 'd-ng' field of violations is a cosmetic change. The template data hash field, which is extended into the TPM PCRs, is not affected by this change and should not affect attestation of the IMA measurement list.

The ADIN1100 uses Auto-Negotiation capability in accordance with IEEE 802.3 Clause 98, providing a mechanism for exchanging information between PHYs to allow link partners to agree to a common mode of operation. The concluded operating mode is the transmit amplitude mode and master/slave preference common across the two devices.

Add a tristate property to advertise desired transmit level. If the device supports the 2.4 Vpp operating mode for 10BASE-T1L, as defined in 802.3gc, and the 2.4 Vpp transmit voltage operation is desired, property should be set to 1. This property is used to select whether Auto-Negotiation advertises a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to 1, the PHY shall advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to zero, the PHY shall not advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode.
