2018-11-01ntb: idt: Alter the driver info commentsSerge Semin3-9/+8

2018-11-01ntb: idt: Discard temperature sensor IRQ handlerSerge Semin2-43/+3
IDT PCIe-switch temperature sensor interface is very broken. First of all only a few combinations of TMPCTL threshold enable bits really cause the interrupts unmasked. Even if an individual bit indicates the event unmasked, corresponding IRQ just isn't generated. Most of the threshold enable bits combinations are in fact useless and non of them can help to create a fully functional alarm interface. So to speak, we can't create a well defined hwmon alarms based on the IDT PCI-switch threshold IRQs. Secondly a single threshold IRQ (not a combination of thresholds) can be successfully enabled without the issue described above. But in this case we experienced an enormous number of interrupts generated by the chip if the temperature got near the enabled threshold value. Filter adjustment didn't help much. It also doesn't provide a hysteresis settings. Due to the temperature sample fluctuations near the threshold the interrupts spate makes the system nearly unusable until the temperature value finally settled so being pushed either to be fully higher or lower the threshold. All of these issues makes the temperature sensor alarm interface useless and even at some point dangerous to be used in the driver. In this case it is safer to completely discard it and disable the temperature alarm interrupts. Signed-off-by: Serge Semin <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2018-11-01ntb: idt: Add basic hwmon sysfs interfaceSerge Semin3-1/+206
IDT PCIe switches provide an embedded temperature sensor working within [0; 127.5]C with resolution of 0.5C. They also can generate a PCIe upstream interrupt in case if the temperature passes through specified thresholds. Since this thresholds interface is very broken the created hwmon-sysfs interface exposes only the next set of hwmon nodes: current input temperature, lowest and highest values measured, history resetting, value offset. HWmon alarm interface isn't provided. IDT PCIe switch also've got an ADC/filter settings of the sensor. This driver doesn't expose them to the hwmon-sysfs interface at the moment, except the offset node. Signed-off-by: Serge Semin <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2018-11-01ntb: idt: Alter temperature read methodSerge Semin2-17/+152
In order to create a hwmon interface for the IDT PCIe-switch temperature sensor the already available reader method should be improved. Particularly we need to redesign it so one would be able to read temperature/offset values from registers of the passed types. Since IDT sensor interface provides temperature in unsigned format 0:7:1 (7 bits for real value and one for fraction) we also need to have helpers for the typical sysfs temperature data type conversion to and from this format. Even though the IDT PCIe-switch provided temperature offset got the same but signed type it can be translated by these methods too.

2018-11-01drm/tilcdc: Use drm_fbdev_generic_setup()Noralf Trønnes1-9/+2
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.

2018-11-01tools headers barrier: Fix arm64 tools build failure wrt ↵Will Deacon1-66/+67
smp_load_{acquire,release} Cheers for reporting this. I managed to reproduce the build failure with gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1). The code in question is the arm64 versions of smp_load_acquire() and smp_store_release(). Unlike other architectures, these are not built around READ_ONCE() and WRITE_ONCE() since we have instructions we can use instead of fences. Bringing our macros up-to-date with those (i.e. tweaking the union initialisation and using the special "uXX_alias_t" types) appears to fix the issue for me.

2018-11-01x86/compat: Adjust in_compat_syscall() to generic code under !COMPATDmitry Safonov7-16/+22
The result of in_compat_syscall() can be pictured as: x86 platform: --------------------------------------------------- | Arch\syscall | 64-bit | ia32 | x32 | |-------------------------------------------------| | x86_64 | false | true | true | |-------------------------------------------------| | i686 | | <true> | | --------------------------------------------------- Other platforms: ------------------------------------------- | Arch\syscall | 64-bit | compat | |-----------------------------------------| | 64-bit | false | true | |-----------------------------------------| | 32-bit(?) | | <false> | ------------------------------------------- As seen, the result of in_compat_syscall() on generic 32-bit platform differs from i686. There is no reason for in_compat_syscall() == true on native i686. It also easy to misread code if the result on native 32-bit platform differs between arches. Because of that non arch-specific code has many places with: if (IS_ENABLED(CONFIG_COMPAT) && in_compat_syscall()) in different variations. It looks-like the only non-x86 code which uses in_compat_syscall() not under CONFIG_COMPAT guard is in amd/amdkfd. But according to the commit a18069c132cb ("amdkfd: Disable support for 32-bit user processes"), it actually should be disabled on native i686. Rename in_compat_syscall() to in_32bit_syscall() for x86-specific code and make in_compat_syscall() false under !CONFIG_COMPAT. A follow on patch will clean up generic users which were forced to check IS_ENABLED(CONFIG_COMPAT) with in_compat_syscall().

IRQ_MATRIX_SIZE is the number of longs needed for a bitmap, multiplied by the size of a long, yielding a byte count. But it is used to size an array of longs, which is way more memory than is needed. Change IRQ_MATRIX_SIZE so it is just the number of longs needed and the arrays come out the correct size.

2018-11-01objtool: Support GCC 9 cold subfunction naming schemeJosh Poimboeuf1-1/+1
Starting with GCC 8, a lot of unlikely code was moved out of line to "cold" subfunctions in .text.unlikely. For example, the unlikely bits of: irq_do_set_affinity() are moved out to the following subfunction: irq_do_set_affinity.cold.49() Starting with GCC 9, the numbered suffix has been removed. So in the above example, the cold subfunction is instead: irq_do_set_affinity.cold() Tweak the objtool subfunction detection logic so that it detects both GCC 8 and GCC 9 naming schemes.

2018-10-31net: stmmac: Fix stmmac_mdio_reset() when building stmmac as modulesNiklas Cassel1-1/+1
When building stmmac, it is only possible to select CONFIG_DWMAC_GENERIC, or any of the glue drivers, when CONFIG_STMMAC_PLATFORM is set. The only exception is CONFIG_STMMAC_PCI. When calling of_mdiobus_register(), it will call our ->reset() callback, which is set to stmmac_mdio_reset(). Most of the code in stmmac_mdio_reset() is protected by a "#if defined(CONFIG_STMMAC_PLATFORM)", which will evaluate to false when CONFIG_STMMAC_PLATFORM=m. Because of this, the phy reset gpio will only be pulled when stmmac is built as built-in, but not when built as modules. Fix this by using "#if IS_ENABLED()" instead of "#if defined()".

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-10-31 This series contains a various collection of fixes. Miroslav Lichvar from Red Hat or should I say IBM now? Updates the PHC timecounter interval for igb so that it gets updated at least once every 550 seconds. Ngai-Mint provides a fix for fm10k to prevent a soft lockup or system crash by adding a new condition to determine if the SM mailbox is in the correct state before proceeding. Jake provides several fm10k fixes, first one marks complier aborts as non-fatal since on some platforms trigger machine check errors when the compile aborts. Added missing device ids to the in-kernel driver. Due to the recent fixes, bumped the driver version. I (Jeff Kirsher) fixed a XFRM_ALGO dependency for both ixgbe and ixgbevf. This fix was based on the original work from Arnd Bergmann, which only fixed ixgbe. Mitch provides a fix for i40e/avf to update the status codes, which resolves an issue between a mis-match between i40e and the iavf driver, which also supports the ice LAN driver. Radoslaw fixes the ixgbe where the driver is logging a message about spoofed packets detected when the VF is re-started with a different MAC address. ==================== Signed-off-by: David S.

2018-10-31ntb: idt: Set PCIe bus address to BARLIMITxSerge Semin1-1/+1
IDT NTB driver sets the upper limit of actual translation address being written to the corresponding memory window setup. It is achieved by BARLIMITx register initialization. Needless to say, that the register works within PCIe bus address space. In general CPU and PCIe address spaces are different. It means, that addresses used for Memory TLPs routine can be different from CPU addresses. While in most of cases they are the same, there are exceptions when the proper mapping must be performed to have the portable driver code. There used to be a virt_to_bus()/bus_to_virt() interface for this purpose. But it's deprecated now. It was also a mistake to use pci_resource_start() since the return address of the method is at the CPU address space. In order to achieve the desired purpose we need to use pci_bus_address() helper. This method shall return a PCIe bus base address of the corresponding BAR resource.
