2023-04-08mtd: spi-nor: sfdp: Add support for SCCR map for multi-chip deviceTakahiro Kuwano
SCCR map for multi-chip devices contains the number of additional dice in the device and register offset values for each additional dice. spi_nor_parse_sccr_mc() is added to determine the number of dice and volatile register offset for each die. The volatile register offset table may already be allocated and contains offset value for die-0 via SCCR map parse. So, we should use devm_krealloc() to expand the table with preserving die-0 offset.

2023-04-08mtd: spi-nor: Extract volatile register offset from SCCR mapTakahiro Kuwano
In use of multi-chip devices, we need to access registers in each die for configuration and status check. The number of dice in the device and volatile register offsets for each die are essential to iterate register access ops. The volatile register offset for the first die resides in the 1st DWORD of SCCR map. Allocate the table and copy the offset value. The table may be allocated when the SCCR map for multi-chip is parsed. Since we cannot assume SCCR parse is always in ahead of SCCR multi-chip, we need to check if the table is already allocated or not.

2023-04-08mtd: spi-nor: Allow post_sfdp hook to return errorsTudor Ambarus
Multi die flashes like s25hl02gt need to determine the page_size at run-time by querying a configuration register for each die. Since the number of dice is determined in an optional SFDP table, SCCR MC, the page size configuration must be done in the post_sfdp hook. Allow post_sfdp to return errors, as reading the configuration register might return errors.

JESD216 SFDP defines in BFPT methods to enter and exit the 4-Byte Address Mode. The flash parameters and settings that are retrieved from SFDP have higher precedence than the static initialized ones, because they should be more accurate and less error prone than those initialized statically. Parse and favor the BFPT-parsed set_4byte_addr_mode methods. Some regressions may be introduced by this patch, because the params->set_4byte_addr_mode method that was set either in spi_nor_init_default_params() or later overwritten in default_init() hooks, are now be overwritten with a different value based on the BFPT data. If that's the case, the fix is to introduce a post_bfpt fixup hook where one should fix the wrong BFPT info.

2023-03-29mtd: spi-nor: Enhance locking to support reads while writesMiquel Raynal
On devices featuring several banks, the Read While Write (RWW) feature is here to improve the overall performance when performing parallel reads and writes at different locations (different banks). The following constraints have to be taken into account: 1#: A single operation can be performed in a given bank. 2#: Only a single program or erase operation can happen on the entire chip (common hardware limitation to limit costs) 3#: Reads must remain serialized even though reads crossing bank boundaries are allowed. 4#: The I/O bus is unique and thus is the most constrained resource, all spi-nor operations requiring access to the spi bus (through the spi controller) must be serialized until the bus exchanges are over. So we must ensure a single operation can be "sent" at a time. 5#: Any other operation that would not be either a read or a write or an erase is considered requiring access to the full chip and cannot be parallelized, we then need to ensure the full chip is in the idle state when this occurs. All these constraints can easily be managed with a proper locking model: 1#: Is enforced by a bitfield of the in-use banks, so that only a single operation can happen in a specific bank at any time. 2#: Is handled by the ongoing_pe boolean which is set before any write or erase, and is released only at the very end of the operation. This way, no other destructive operation on the chip can start during this time frame. 3#: An ongoing_rd boolean allows to track the ongoing reads, so that only one can be performed at a time. 4#: An ongoing_io boolean is introduced in order to capture and serialize bus accessed. This is the one being released "sooner" than before, because we only need to protect the chip against other SPI accesses during the I/O phase, which for the destructive operations is the beginning of the operation (when we send the command cycles and possibly the data), while the second part of the operation (the erase delay or the programmation delay) is when we can do something else in another bank. 5#: Is handled by the three booleans presented above, if any of them is set, the chip is not yet ready for the operation and must wait. All these internal variables are protected by the existing lock, so that changes in this structure are atomic. The serialization is handled with a wait queue.

They will soon be improved in a followup commit which actually brings the logic, but I figured out it was more readable to do it this way.

The other pair is suffixed _rd which stands for "read" and hence is being called by spi_nor_read().

The ->prepare()/->unprepare() hooks are now legacy, we no longer accept new drivers supporting them. The only remaining controllers using them acquires a per-chip mutex, which should not interfere with the rest of the operation done in the core. As a result, we should be safe to reorganize these helpers to first perform the preparation, before acquiring the core locks. This is necessary in order to be able to improve the locking mechanism in the core (coming next). No side effects are expected.

2023-03-12tpm: disable hwrng for fTPM on some AMD designsMario Limonciello
AMD has issued an advisory indicating that having fTPM enabled in BIOS can cause "stuttering" in the OS. This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439d58db ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.

2023-03-12tpm/eventlog: Don't abort tpm_read_log on faulty ACPI addressMorten Linderud
tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI table is found. If the firmware vendor includes an invalid log address we are unable to map from the ACPI memory and tpm_read_log() returns -EIO which would abort discovery of the eventlog. Change the return value from -EIO to -ENODEV when acpi_os_map_iomem() fails to map the event log. The following hardware was used to test this issue: Framework Laptop (Pre-production) BIOS: INSYDE Corp, Revision: 3.2 TPM Device: NTC, Firmware Revision: 7.2 Dump of the faulty ACPI TPM2 table: [000h 0000 4] Signature : "TPM2" [Trusted Platform Module hardware interface Table] [004h 0004 4] Table Length : 0000004C [008h 0008 1] Revision : 04 [009h 0009 1] Checksum : 2B [00Ah 0010 6] Oem ID : "INSYDE" [010h 0016 8] Oem Table ID : "TGL-ULT" [018h 0024 4] Oem Revision : 00000002 [01Ch 0028 4] Asl Compiler ID : "ACPI" [020h 0032 4] Asl Compiler Revision : 00040000 [024h 0036 2] Platform Class : 0000 [026h 0038 2] Reserved : 0000 [028h 0040 8] Control Address : 0000000000000000 [030h 0048 4] Start Method : 06 [Memory Mapped I/O] [034h 0052 12] Method Parameters : 00 00 00 00 00 00 00 00 00 00 00 00 [040h 0064 4] Minimum Log Length : 00010000 [044h 0068 8] Log Address : 000000004053D000 Fixes: 0cf577a03f21 ("tpm: Fix handling of missing event log") Tested-by: Erkki Eilonen <erkki@bearmetal.eu> Signed-off-by: Morten Linderud <morten@linderud.pw> Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

2023-03-12cpumask: relax sanity checking constraintsLinus Torvalds
The cpumask_check() was unnecessarily tight, and causes problems for the users of cpumask_next(). We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.

We do not need to set EXT4_STATE_MAY_INLINE_DATA flag here, since ext4_mark_inode_dirty() already sets this flag if needed. Setting EXT4_STATE_MAY_INLINE_DATA when it is needed may trigger a BUG_ON in ext4_writepages().

2023-03-11ext4: move where set the MAY_INLINE_DATA flag is setYe Bin
The only caller of ext4_find_inline_data_nolock() that needs setting of EXT4_STATE_MAY_INLINE_DATA flag is ext4_iget_extra_inode(). In ext4_write_inline_data_end() we just need to update inode->i_inline_off. Since we are going to add one more caller that does not need to set EXT4_STATE_MAY_INLINE_DATA, just move setting of EXT4_STATE_MAY_INLINE_DATA out to ext4_iget_extra_inode().
