2022-11-18dm integrity: clear the journal on suspendMikulas Patocka
There was a problem that a user burned a dm-integrity image on CDROM and could not activate it because it had a non-empty journal. Fix this problem by flushing the journal (done by the previous commit) and clearing the journal (done by this commit). Once the journal is cleared, dm-integrity won't attempt to replay it on the next activation. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@kernel.org>

This commit flushes the journal on suspend. It is prerequisite for the next commit that enables activating dm integrity devices in read-only mode. Note that we deliberately didn't flush the journal on suspend, so that the journal replay code would be tested. However, the dm-integrity code is 5 years old now, so that journal replay is well-tested, and we can make this change now.

2022-11-18drm/i915/tgl+: Enable display DC power states on all eDP portsImre Deak
Starting with TGL eDP is supported on ports B+ (besides port A), so make sure DC states are not blocked on any such ports. For this add an AUX_IO_<port> power domain for each port with eDP support.

2022-11-18drm/i915: Use the AUX_IO power domain only for eDP/PSR portImre Deak
Use the AUX_IO_A display power domain only for eDP on port A where PSR is also supported. This is the case where DC states need to be enabled while the output is enabled - ensured by AUX_IO_A domain not enabling the DC_OFF power well. Otherwise port A can be treated the same way as other ports with an external DP output: using the AUX_<port> domain which disables the unrequired DC states. This change prepares for the next patch enabling DC states on all ports supporting eDP/PSR besides port A. v2: - Check the encoder PSR capability instead of PSR being enabled in the crtc_state, as the latter can be changed with a fastset.

2022-11-18drm/i915: Preallocate the debug power domain wakerefs arrayImre Deak
Since the current size of intel_display_power_domain_set struct is close to 1kB, it's better to use preallocated memory for it. The only user of the intel_display_power_get/put_in_set() allocating the struct on stack is hsw_get_pipe_config(), so we can avoid potential stack overallocations by moving the struct here to the preallocated intel_crtc struct (hsw_get_pipe_config() is non-reentrant wrt. each CRTC).

2022-11-18dm ioctl: fix misbehavior if list_versions races with module loadingMikulas Patocka
__list_versions will first estimate the required space using the "dm_target_iterate(list_version_get_needed, &needed)" call and then will fill the space using the "dm_target_iterate(list_version_get_info, &iter_info)" call. Each of these calls locks the targets using the "down_read(&_lock)" and "up_read(&_lock)" calls, however between the first and second "dm_target_iterate" there is no lock held and the target modules can be loaded at this point, so the second "dm_target_iterate" call may need more space than what was the first "dm_target_iterate" returned. The code tries to handle this overflow (see the beginning of list_version_get_info), however this handling is incorrect. The code sets "param->data_size = param->data_start + needed" and "iter_info.end = (char *)vers+len" - "needed" is the size returned by the first dm_target_iterate call; "len" is the size of the buffer allocated by userspace. "len" may be greater than "needed"; in this case, the code will write up to "len" bytes into the buffer, however param->data_size is set to "needed", so it may write data past the param->data_size value. The ioctl interface copies only up to param->data_size into userspace, thus part of the result will be truncated. Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this guarantees that the second "dm_target_iterate" call will write only up to the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it overflows the "needed" space - in this case, userspace will allocate a larger buffer and retry. Note that there is also a bug in list_version_get_needed - we need to add "strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

2022-11-18gpu: host1x: Avoid trying to use GART on Tegra20Robin Murphy
Since commit c7e3ca515e78 ("iommu/tegra: gart: Do not register with bus") quite some time ago, the GART driver has effectively disabled itself to avoid issues with the GPU driver expecting it to work in ways that it doesn't. As of commit 57365a04c921 ("iommu: Move bus setup to IOMMU device registration") that bodge no longer works, but really the GPU driver should be responsible for its own behaviour anyway. Make the workaround explicit.

2022-11-17drm/amdgpu: Interpret IPMI data for product information (v2)Luben Tuikov
Don't assume FRU MCU memory locations for the FRU data fields, or their sizes, instead read and interpret the IPMI data, as stipulated in the IPMI spec version 1.0 rev 1.2. Extract the Product Name, Product Part/Model Number, and the Product Serial Number by interpreting the IPMI data. Check the checksums of the stored IPMI data to make sure we don't read and give corrupted data back the the user. Eliminate small I2C reads, and instead read the whole Product Info Area in one go, and then extract the information we're seeking from it. Eliminates a whole function, making this file smaller. v2: Clarify changes in the commit message.
