2021-10-12hwmon: cleanup non-bool "valid" data fieldsPaul Fertser
We have bool so use it consistently in all the drivers. The following Coccinelle script was used: @@ identifier T; type t = { char, int }; @@ struct T { ... - t valid; + bool valid; ... } @@ identifier v; @@ ( - v->valid = 0 + v->valid = false | - v->valid = 1 + v->valid = true ) followed by sed to fixup the comments: sed '/bool valid;/{s/!=0/true/;s/zero/false/}' Few whitespace changes were fixed manually. All modified drivers were compile-tested.

2020-11-12hwmon: (applesmc) Re-work SMC commsBrad Campbell
Commit fff2d0f701e6 ("hwmon: (applesmc) avoid overlong udelay()") introduced an issue whereby communication with the SMC became unreliable with write errors like : [ 120.378614] applesmc: send_byte(0x00, 0x0300) fail: 0x40 [ 120.378621] applesmc: LKSB: write data fail [ 120.512782] applesmc: send_byte(0x00, 0x0300) fail: 0x40 [ 120.512787] applesmc: LKSB: write data fail The original code appeared to be timing sensitive and was not reliable with the timing changes in the aforementioned commit.

2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.

2012-07-27hwmon: (applesmc) Decode and act on read/write status codesHenrik Rydberg
The behavior of the SMC has changed several times over the years, causing read failures in the driver. It seems the problem can be explained by a shift in SMC speed combined with improper action on status codes. We should first wait for the SMC to settle, which was the most frequent response on the old slow machines. Then, if the SMC is busy, we need to try again later by resending the command. This was the most likely response until 2012. Now, with a shorter wait time, we are again most likely to poll while the SMC is settling, and as a result we see high failure rates on many old and new models. With the distinction between busy and failure, we can also wait longer before retrying, without sacrificing speed. This seems to bring failures down to virtually zero on all models.

2012-07-21hwmon: (applesmc) Allow negative temperature valuesHenrik Rydberg
There are many userland reports of sensors with unreasonably small and large temperatures. There seem to be several reasons for this: Firstly, the major sensor type (sp78) is actually a signed number. This explains why some sensors show very small or large values - they are in fact all small, but of different sign. Secondly, the other sensor type (1-hex) is not properly understood; it may be that it is not a temperature after all. Thirdly, some sensors are differential in nature, showing changes over time rather than absolute numbers. This explains why those values are small and of varying sign. This patch interprets the sp78 type as signed short, but keeps the original scaling. For other types, -EINVAL is returned, since the nature of those sensors is unknown.

2012-07-21hwmon: (applesmc) Shorten minimum wait timeHenrik Rydberg
The 2012 series of MacBooks have a faster SMC, and the current driver timings do not work at all. Tests show that decreasing the minimum wait time, from 64 us to 16 us, works well. Since this is still larger than the original minimum of 10 us used before 2008, there is nothing inherently problematic with changing it. The fail frequency on older machines seems to increase slightly, but not enough to be noticeable. Tested on MBA11, MBA31, MBA5,2, MBP9,2. The patch was originally written by adamski99 (ubuntuforums.org) and later tested by janhouse (bbs.archlinux.org).
