2022-05-20hwmon: (nct6775) Split core and platform driverZev Weiss6-1433/+1526
This splits the nct6775 driver into an interface-independent core and a separate platform driver that wraps inb/outb port I/O (or asuswmi methods) around that core.

2022-05-20hwmon: (nct6775) Add read-only modeZev Weiss1-6/+12
When enabled, all write bits are removed from the modes of all sysfs attribute files. This provides a bit of infrastructure for the upcoming i2c version of this driver, which should generally avoid writes to device registers so as not to interfere with simultaneous use of the device via the LPC interface.

2022-05-20hwmon: (nct6775) Rearrange attr-group initializationZev Weiss1-42/+42
We now track the number of attribute groups in nct6775_data, as a measure to simplify handling differences in the set of enabled attribute groups between nct6775 drivers (platform & i2c). As a side effect, we also reduce the amount of IS_ERR()/PTR_ERR() boilerplate a bit.

2022-05-20hwmon: (nct6775) Convert register access to regmap APIZev Weiss1-315/+662
This replaces the nct6775_data->{read,write}_value function pointers with a regmap. The major difference is that the regmap access functions may fail, and hence require checking at each call site. While the existing WMI register-access code had potential failure paths, they were masked by the fact that the read_value() function returned the register value directly, and hence squashed errors undetectably by simply returning zero, and while the write_value() functions were capable of reporting errors, all callers ignored them. This improves the robustness of the existing code, and also prepares the driver for an i2c version to be added soon, for which register accesses are much more likely to actually fail. The conversion of the register-access call sites is largely mechanical (reading a register now returns the value via an out-param pointer, and returned errors must be checked for and propagated to callers), though the nct6775_write_fan_div() function is refactored slightly to avoid duplicating nearly identical (and now lengthier) code in each switch case.

2022-05-20hwmon: (dell-smm) Avoid unnecessary SMM calls during initArmin Wolf1-23/+14
When the driver tries to detect the fan multiplier during module initialisation, it issues one SMM call for each fan. Those SMM calls are however redundant and also try to query fans which may not be present. Fix that by detecting the fan multiplier during hwmon initialisation when no extra SMM calls are needed. Also dont assume the last nominal speed entry to be the biggest and instead check all entries.

We're having unresolved issues with the glock holder auto-demotion mechanism introduced in commit dc732906c245. This mechanism was assumed to be essential for avoiding frequent short reads and writes until commit 296abc0d91d8 ("gfs2: No short reads or writes upon glock contention"). Since then, when the inode glock is lost, it is simply re-acquired and the operation is resumed. This means that apart from the performance penalty, we might as well drop the inode glock before faulting in pages, and re-acquire it afterwards.

2022-05-13gfs2: buffered write prefaultingAndreas Gruenbacher1-12/+16
In gfs2_file_buffered_write, to increase the likelihood that all the user memory we're trying to write will be resident in memory, carry out the write in chunks and fault in each chunk of user memory before trying to write it. Otherwise, some workloads will trigger frequent short "internal" writes, causing filesystem blocks to be allocated and then partially deallocated again when writing into holes, which is wasteful and breaks reservations. Neither the chunked writes nor any of the short "internal" writes are user visible. Signed-off-by: Andreas Gruenbacher <[email protected]>

2022-05-13gfs2: Align read and write chunks to the page cacheAndreas Gruenbacher1-8/+7
Align the chunks that reads and writes are carried out in to the page cache rather than the user buffers. This will be more efficient in general, especially for allocating writes. Optimizing the case that the user buffer is gfs2 backed isn't very useful; we only need to make sure we won't deadlock. Signed-off-by: Andreas Gruenbacher <[email protected]>
2022-05-13gfs2: Pull return value test out of should_fault_in_pagesAndreas Gruenbacher1-12/+22
Pull the return value test of the previous read or write operation out of should_fault_in_pages(). In a following patch, we'll fault in pages before the I/O and there will be no return value to check. Signed-off-by: Andreas Gruenbacher <[email protected]>

2022-05-13gfs2: Variable renameAndreas Gruenbacher1-17/+17
Instead of counting the number of bytes read from the filesystem, functions gfs2_file_direct_read and gfs2_file_read_iter count the number of bytes written into the user buffer. Conversely, functions gfs2_file_direct_write and gfs2_file_buffered_write count the number of bytes read from the user buffer. This is nothing but confusing, so change the read functions to count how many bytes they have read, and the write functions to count how many bytes they have written.

2022-05-13gfs2: Fix filesystem block deallocation for short writesAndreas Gruenbacher1-6/+5
When a write cannot be carried out in full, gfs2_iomap_end() releases blocks that have been allocated for this write but haven't been used. To compute the end of the allocation, gfs2_iomap_end() incorrectly rounded the end of the attempted write down to the next block boundary to arrive at the end of the allocation. It would have to round up, but the end of the allocation is also available as iomap->offset + iomap->length, so just use that instead. In addition, use round_up() for computing the start of the unused range. Fixes: 64bc06bb32ee ("gfs2: iomap buffered write support") Signed-off-by: Andreas Gruenbacher <[email protected]>
