| * pinctrl: API changes to support multiple states per deviceStephen Warren2012-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The API model is changed from: p = pinctrl_get(dev, "state1"); pinctrl_enable(p); ... pinctrl_disable(p); pinctrl_put(p); p = pinctrl_get(dev, "state2"); pinctrl_enable(p); ... pinctrl_disable(p); pinctrl_put(p); to this: p = pinctrl_get(dev); s1 = pinctrl_lookup_state(p, "state1"); s2 = pinctrl_lookup_state(p, "state2"); pinctrl_select_state(p, s1); ... pinctrl_select_state(p, s2); ... pinctrl_put(p); This allows devices to directly transition between states without disabling the pin controller programming and put()/get()ing the configuration data each time. This model will also better suit pinconf programming, which doesn't have a concept of "disable". The special-case hogging feature of pin controllers is re-written to use the regular APIs instead of special-case code. Hence, the pinmux-hogs debugfs file is removed; see the top-level pinctrl-handles files for equivalent data.

| * pinctrl: assume map table entries can't have a NULL name fieldStephen Warren2012-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pinctrl_register_mappings() already requires that every mapping table entry have a non-NULL name field. Logically, this makes sense too; drivers should always request a specific named state so they know what they're getting. Relying on getting the first mentioned state in the mapping table is error-prone, and a nasty special case to implement, given that a given the mapping table may define multiple states for a device. Remove a small part of the documentation that talked about optionally requesting a specific state; it's mandatory now.

It also inhibits cpufreq scaling drivers to load so that only the hypervisor can make power management decisions - fixing a weird perf bug. There is one thing in the Kconfig that you won't like: "default y if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by default is off). I've a fix to convert that boolean expression into "default m" which I am going to post after the cpufreq git pull - as the two patches to make this work depend on a fix in Dave Jones's tree. - Function Level Reset (FLR) support in the Xen PCI backend.

SysRq+F manually invokes the global oom killer to kill a memory-hogging task. This is normally done as a last resort to free memory when no progress is being made or to test the oom killer itself. For both uses, we always want to kill a thread and never defer. This patch causes SysRq+F to always kill an eligible thread and can be used to force a kill even if another oom killed thread has failed to exit.

It is going to be a bit more nasty than usual as in touching things outside of arch/powerpc mostly due to the big iSeriesectomy :-) We finally got rid of the bugger (legacy iSeries support) which was a PITA to maintain and that nobody really used anymore. Here are some of the highlights: - Legacy iSeries is gone. Thanks Stephen ! There's still some bits and pieces remaining if you do a grep -ir series arch/powerpc but they are harmless and will be removed in the next few weeks hopefully. - The 'fadump' functionality (Firmware Assisted Dump) replaces the previous (equivalent) "pHyp assisted dump"... it's a rewrite of a mechanism to get the hypervisor to do crash dumps on pSeries, the new implementation hopefully being much more reliable. Thanks Mahesh Salgaonkar. - The "EEH" code (pSeries PCI error handling & recovery) got a big spring cleaning, motivated by the need to be able to implement a new backend for it on top of some new different type of firwmare. The work isn't complete yet, but a good chunk of the cleanups is there. Note that this adds a field to struct device_node which is not very nice and which Grant objects to. I will have a patch soon that moves that to a powerpc private data structure (hopefully before rc1) and we'll improve things further later on (hopefully getting rid of the need for that pointer completely). Thanks Gavin Shan. - I dug into our exception & interrupt handling code to improve the way we do lazy interrupt handling (and make it work properly with "edge" triggered interrupt sources), and while at it found & fixed a wagon of issues in those areas, including adding support for page fault retry & fatal signals on page faults. - Your usual random batch of small fixes & updates, including a bunch of new embedded boards, both Freescale and APM based ones, etc..."

This patch address the issue with a combination of two patches suggested by Russell King that clears and mask all interrupts at probe() and clears any pending error and RX interrupts at port startup time. We suspect the spurious interrupts are a side-effect of switching the UART from FIFO to non-FIFO mode.

These in turn go after the contained normal port struct which actually has the actual in/out accessors. But what is happening in some cases, is that a function is passed in a port struct, and it runs container_of to get the 8250_port struct, and then it uses serial_in/out helpers on that. But when you do, it goes full circle, since it jumps back inside the 8250_port to find the contained port struct (which we already knew!). So, if we are operating in a scope where we know the struct port, then use the serial_port_in/out helpers and avoid the bouncing around. If we don't have the struct port handy, and it isn't worth making a local for it, then just leave things as-is which uses the serial_in/out helpers that will resolve the 8250_port onto the struct port. Mostly, gcc figures this out on its own -- so this doesn't bring to the table any revolutionary runtime delta. However, it is somewhat misleading to always hammer away on 8250 structs, when the actual underlying property isn't at all 8250 specific -- and this change makes that clear.

However there are a lot of cases where we have access directly to the port pointer, but yet go through the parent 8250_port structure instead to get it. These should just use the port struct directly. Similarly there are cases where it makes sense (from a code cleanliness point of view) to declare a local for the port struct, so we aren't going through the parent 8250_port struct repeatedly to get to it. We get a small reduction in text size, but it appears that gcc was smart enough to internally be doing most of this already, so the readability improvement is the larger gain.

They are implemented as macros a ways down in the file. This isn't by accident, but is implicitly required, so cpp doesn't mangle other instances of the common string "serial_in", as it exists as a field in the port struct itself. The above mangling avoidance violates the principle of least surprise, and it also prevents the shortcuts from being relocated up to the top of file, or into 8250.h -- either being a better location than the current one. Move them to 8250.h so other 8250-like drivers can also use the shortcuts, and in the process, make the conflicting names go away by using static inlines instead of macros. The object file size remains unchanged with this modification.

The current calculation (introduced with commit 0d1f22e4) in the kernel preferes this low prescaler as often as possible, but with some imprecise counterparts the communication on low baudrates fails. According a support-mail from freescale the low prescaler (/4) allows just 1% tolerance in bittiming in contrast to 4% of the high prescaler (/32). The prescaler not only affects the baudrate-calculation, but also the sampling of the bits on the wire. With this patch, we use the slightly less precise, but higher tolerant prescaler calculation on low baudrates up to (and including) 115200 baud and the more precise calculation above. Tested on a custom MPC5200B board with "fsl,mpc5200b-psc-uart". Calculation Examples with prescaler (PS) 4 and 32 and divisor (DIV) on various baudrates. Real stands for the real baudrate generated and Diff for the differences between: 50 Baud PS 32 DIV 0xa122 Real 50 Diff 0.00% 75 Baud PS 32 DIV 0x6b6c Real 75 Diff 0.00% 110 Baud PS 32 DIV 0x493e Real 110 Diff 0.00% 134 Baud PS 32 DIV 0x3c20 Real 133 Diff 0.75% 150 Baud PS 32 DIV 0x35b6 Real 150 Diff 0.00% 200 Baud PS 32 DIV 0x2849 Real 199 Diff 0.50% 300 Baud PS 4 DIV 0xd6d8 Real 300 Diff 0.00% PS 32 DIV 0x1adb Real 300 Diff 0.00% 600 Baud PS 4 DIV 0x6b6c Real 600 Diff 0.00% PS 32 DIV 0x0d6e Real 599 Diff 0.17% 1200 Baud PS 4 DIV 0x35b6 Real 1200 Diff 0.00% PS 32 DIV 0x06b7 Real 1199 Diff 0.08% 1800 Baud PS 4 DIV 0x23cf Real 1799 Diff 0.06% PS 32 DIV 0x047a Real 1799 Diff 0.06% 2400 Baud PS 4 DIV 0x1adb Real 2400 Diff 0.00% PS 32 DIV 0x035b Real 2401 Diff - 0.04% 4800 Baud PS 4 DIV 0x0d6e Real 4799 Diff 0.02% PS 32 DIV 0x01ae Real 4796 Diff 0.08% 9600 Baud PS 4 DIV 0x06b7 Real 9598 Diff 0.02% PS 32 DIV 0x00d7 Real 9593 Diff 0.07% 19200 Baud PS 4 DIV 0x035b Real 19208 Diff - 0.04% PS 32 DIV 0x006b Real 19275 Diff - 0.39% 38400 Baud PS 4 DIV 0x01ae Real 38372 Diff 0.07% PS 32 DIV 0x0036 Real 38194 Diff 0.54% 57600 Baud PS 4 DIV 0x011e Real 57692 Diff - 0.16% PS 32 DIV 0x0024 Real 57291 Diff 0.54% 76800 Baud PS 4 DIV 0x00d7 Real 76744 Diff 0.07% PS 32 DIV 0x001b Real 76388 Diff 0.54% 115200 Baud PS 4 DIV 0x008f Real 115384 Diff - 0.16% PS 32 DIV 0x0012 Real 114583 Diff 0.54% 153600 Baud PS 4 DIV 0x006b Real 154205 Diff - 0.39% PS 32 DIV 0x000d Real 158653 Diff - 3.29% 230400 Baud PS 4 DIV 0x0048 Real 229166 Diff 0.54% PS 32 DIV 0x0009 Real 229166 Diff 0.54% 307200 Baud PS 4 DIV 0x0036 Real 305555 Diff 0.54% PS 32 DIV 0x0007 Real 294642 Diff 4.09% 460800 Baud PS 4 DIV 0x0024 Real 458333 Diff 0.54% PS 32 DIV 0x0005 Real 412500 Diff 10.48% 500000 Baud PS 4 DIV 0x0021 Real 500000 Diff 0.00% PS 32 DIV 0x0004 Real 515625 Diff - 3.13% 576000 Baud PS 4 DIV 0x001d Real 568965 Diff 1.22% PS 32 DIV 0x0004 Real 515625 Diff 10.48% 614400 Baud PS 4 DIV 0x001b Real 611111 Diff 0.54% PS 32 DIV 0x0003 Real 687500 Diff -11.90% 921600 Baud PS 4 DIV 0x0012 Real 916666 Diff 0.54% PS 32 DIV 0x0002 Real 1031250 Diff -11.90% 1000000 Baud PS 4 DIV 0x0011 Real 970588 Diff 2.94% PS 32 DIV 0x0002 Real 1031250 Diff - 3.13% 1152000 Baud PS 4 DIV 0x000e Real 1178571 Diff - 2.31% PS 32 DIV 0x0002 Real 1031250 Diff 10.48% 1500000 Baud PS 4 DIV 0x000b Real 1500000 Diff 0.00% PS 32 DIV 0x0001 Real 2062500 Diff -37.50% 2000000 Baud PS 4 DIV 0x0008 Real 2062500 Diff - 3.13% PS 32 DIV 0x0001 Real 2062500 Diff - 3.13% 2500000 Baud PS 4 DIV 0x0007 Real 2357142 Diff 5.71% PS 32 DIV 0x0001 Real 2062500 Diff 17.50% 3000000 Baud PS 4 DIV 0x0006 Real 2750000 Diff 8.33% PS 32 DIV 0x0001 Real 2062500 Diff 31.25% 3500000 Baud PS 4 DIV 0x0005 Real 3300000 Diff 5.71% PS 32 DIV 0x0001 Real 2062500 Diff 41.07% 4000000 Baud PS 4 DIV 0x0004 Real 4125000 Diff - 3.13% PS 32 DIV 0x0001 Real 2062500 Diff 48.44% Signed-off-by: Frank Benkert <frank.benkert@avat.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The current code means the start() just returns without doing anything.

This was not good. Fix this by turning interrupts at an appropriate place. (The race is protected by CLOSING flag.) After the move, the code is identical to tty_port_close_end, so use it!
