[opensuse-kernel] [CONFIG] Disabled options
by Jeff Mahoney 13 Jun '12

13 Jun '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all - Just a quick heads up that I've disabled a bunch of options on the HEAD kernel. I've disabled DECNet and ARCnet. I've disabled LocalTalk drivers on i386-default. I've disabled many drivers that can only be used on embedded hardware. While I don't doubt that there are users out there playing with Linux on embedded hardware - I do doubt that they're using an openSUSE-built kernel RPM. The disabled modules include voltage regulators, multifunction devices that are typically found on SoCs, IIO sensor drivers, SPI drivers, and drivers only used on Intel Medfield or Moorestown. I'd like to try to clear out as many of the drivers we're building that are inappropriate for desktop, server, or notebook systems. That includes drivers that are only used for embedded devices and hardware that is so ancient that nobody is likely to be using it anymore. The former is pretty easy but the latter gets tricky. The goal is to save on users' disk space, download bandwidth, and build resources. DECNet and ARCnet were rare already in my former life as a sysadmin. That was over 10 years ago. Here's the full list of disabled options: CONFIG_ARCNET CONFIG_ARCNET_1051 CONFIG_ARCNET_1201 CONFIG_ARCNET_CAP CONFIG_ARCNET_COM20020_CS CONFIG_ARCNET_COM20020 CONFIG_ARCNET_COM20020_PCI CONFIG_ARCNET_COM90xxIO CONFIG_ARCNET_COM90xx CONFIG_ARCNET_RAW CONFIG_ARCNET_RIM_I CONFIG_DECNET CONFIG_DECNET_NF_GRABULATOR CONFIG_COPS CONFIG_LTPC CONFIG_AD2S1200, CONFIG_AD2S1210, CONFIG_AD2S90, CONFIG_AD5064, CONFIG_AD5360, CONFIG_AD5380, CONFIG_AD5421, CONFIG_AD5446, CONFIG_AD5504, CONFIG_AD5624R_SPI, CONFIG_AD5686, CONFIG_AD5764, CONFIG_AD5791, CONFIG_AD5930, CONFIG_AD5933, CONFIG_AD7150, CONFIG_AD7152, CONFIG_AD7192, CONFIG_AD7280, CONFIG_AD7291, CONFIG_AD7298, CONFIG_AD7476, CONFIG_AD7606_IFACE_PARALLEL, CONFIG_AD7606_IFACE_SPI, CONFIG_AD7606, CONFIG_AD7746, CONFIG_AD7780, CONFIG_AD7793, CONFIG_AD7816, CONFIG_AD7887, CONFIG_AD799X, CONFIG_AD799X_RING_BUFFER, CONFIG_AD9832, CONFIG_AD9834, CONFIG_AD9850, CONFIG_AD9852, CONFIG_AD9910, CONFIG_AD9951, CONFIG_ADE7753, CONFIG_ADE7754, CONFIG_ADE7758, CONFIG_ADE7759, CONFIG_ADE7854_I2C, CONFIG_ADE7854, CONFIG_ADE7854_SPI, CONFIG_ADIS16060, CONFIG_ADIS16080, CONFIG_ADIS16130, CONFIG_ADIS16201, CONFIG_ADIS16203, CONFIG_ADIS16204, CONFIG_ADIS16209, CONFIG_ADIS16220, CONFIG_ADIS16240, CONFIG_ADIS16260, CONFIG_ADIS16400, CONFIG_ADT7310, CONFIG_ADT7316_I2C, CONFIG_ADT7316, CONFIG_ADT7316_SPI, CONFIG_ADT7410, CONFIG_ADXRS450, CONFIG_BACKLIGHT_WM831X, CONFIG_CAN_JANZ_ICAN3, CONFIG_FB_SM501, CONFIG_GPIO_JANZ_TTL, CONFIG_GPIO_RDC321X, CONFIG_GPIO_STMPE, CONFIG_GPIO_TIMBERDALE, CONFIG_GPIO_WM831X, CONFIG_IIO_BUFFER, CONFIG_IIO_CONSUMERS_PER_TRIGGER=2, CONFIG_IIO_GPIO_TRIGGER, CONFIG_IIO_KFIFO_BUF, CONFIG_IIO, CONFIG_IIO_PERIODIC_RTC_TRIGGER, CONFIG_IIO_SIMPLE_DUMMY, CONFIG_IIO_ST_HWMON, CONFIG_IIO_SW_RING, CONFIG_IIO_SYSFS_TRIGGER, CONFIG_IIO_TRIGGER, CONFIG_INPUT_MC13783_PWRBUTTON, CONFIG_INPUT_WM831X_ON, CONFIG_KEYBOARD_STMPE, CONFIG_KXSD9, CONFIG_LEDS_MC13783, CONFIG_LEDS_REGULATOR, CONFIG_LEDS_WM831X_STATUS, CONFIG_LIS3L02DQ_BUF_KFIFO, CONFIG_LIS3L02DQ, CONFIG_MAX1363, CONFIG_MAX1363_RING_BUFFER, CONFIG_MAX517, CONFIG_MFD_CORE, CONFIG_MFD_JANZ_CMODIO, CONFIG_MFD_MC13783, CONFIG_MFD_MC13XXX, CONFIG_MFD_RDC321X, CONFIG_MFD_SM501_GPIO, CONFIG_MFD_SM501, CONFIG_MFD_STMPE, CONFIG_MFD_TIMBERDALE, CONFIG_MFD_TPS65217, CONFIG_MFD_WM831X_SPI, CONFIG_MFD_WM831X, CONFIG_MFD_WM8400, CONFIG_RADIO_TIMBERDALE, CONFIG_REGMAP_I2C, CONFIG_REGMAP_SPI, CONFIG_REGMAP, CONFIG_REGULATOR_AD5398, CONFIG_REGULATOR_DA903X, CONFIG_REGULATOR_DEBUG, CONFIG_REGULATOR_DUMMY, CONFIG_REGULATOR_FIXED_VOLTAGE, CONFIG_REGULATOR_GPIO, CONFIG_REGULATOR_ISL6271A, CONFIG_REGULATOR_LP3971, CONFIG_REGULATOR_LP3972, CONFIG_REGULATOR_MAX1586, CONFIG_REGULATOR_MAX8649, CONFIG_REGULATOR_MAX8660, CONFIG_REGULATOR_MAX8952, CONFIG_REGULATOR_MC13783, CONFIG_REGULATOR_MC13892, CONFIG_REGULATOR_MC13XXX_CORE, CONFIG_REGULATOR_PCAP, CONFIG_REGULATOR_TPS6105X, CONFIG_REGULATOR_TPS62360, CONFIG_REGULATOR_TPS65023, CONFIG_REGULATOR_TPS6507X, CONFIG_REGULATOR_TPS65217, CONFIG_REGULATOR_TPS6524X, CONFIG_REGULATOR_USERSPACE_CONSUMER, CONFIG_REGULATOR_VIRTUAL_CONSUMER, CONFIG_REGULATOR_WM831X, CONFIG_REGULATOR_WM8400, CONFIG_REGULATOR, CONFIG_RFKILL_REGULATOR, CONFIG_RTC_DRV_MC13XXX, CONFIG_RTC_DRV_WM831X, CONFIG_SCA3000, CONFIG_SENSORS_AK8975, CONFIG_SENSORS_HMC5843, CONFIG_SENSORS_ISL29018, CONFIG_SENSORS_MC13783_ADC, CONFIG_SENSORS_TSL2563, CONFIG_SENSORS_WM831X, CONFIG_SERIAL_MFD_HSU, CONFIG_SERIAL_UARTLITE, CONFIG_STMPE_I2C, CONFIG_STMPE_SPI, CONFIG_TOUCHSCREEN_MC13783, CONFIG_TOUCHSCREEN_STMPE, CONFIG_TOUCHSCREEN_WM831X, CONFIG_TPS6105X, CONFIG_TSL2583, CONFIG_WM831X_BACKUP, CONFIG_WM831X_POWER, CONFIG_WM831X_WATCHDOG - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJPmYT7AAoJEB57S2MheeWyrW0P/i+Obf4QMQIr0xTD7YoNbczI LLYc92bYZ5vPPLq+Cl+V8Mv0DkMw6n9OziJ6KpB2xklgNHgmEqM0Hk7A6UdV8Ms9 BfnoZiEVOrj5TpgeTNL6j39/cMKaA0bXeU5ZotPJLxUlakxfhtJkwEzkhhThtZLV ewIzOSIXV4IoEhUgKCEhd/F3TRpvotAe/rTybiujxrvFUj8fq/+GRThklNtSmvqf 2+IvS2bfiDqdx88nMq5QIHwjOnfDrFLgsf2dDt46710SaUlaPogZPo6k3bBaaNLi rC0wzTRPTtrmFiEq/XI1jncbFBNb4ne1ys77dsaM//mkRDLKntNyOBMnxV0tlw+j RQA6WB1tp9qwMPrtXYMtJoEKgj7sXwBlPLql5aaF3cIpW4hsIzq3Cpnfn02ddnjf aUHgFtZZTEHCUg7iaMKNqMNDCED5z/6DwYXArgQewZP2SQJYIVpSMFwu7U48Jakr VDaUf9QTcIMxD/j8Ng3cXj3a1UbiVtjl8uM4rHUThTZjI+99ieN92J239qXPjfVH eC5ewwm2eXOmOTtSYUnoAs7pbUUZDVxYCPc68PoPzaG63HZjqje0+kIuxlEWqi0+ JrywGOZfBJYp4dbCzyc8iMMMjWwbHAbMT5SPWxrgG6QRiPH2vGoR5742kHh4eX73 9Y/MR9Yyc9B/O+Qh5wBO =2CJZ -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] [PATCH] LKDB: Fix usability issues with 'enter'.
by Andrei Warkentin 04 May '12

04 May '12

This fixes the following problems: 1) Typematic-repeat of 'enter' gives warning message. 2) Use of 'keypad enter' gives warning message. 3) Lag on the order of seconds between "break" and "make" when expecting the enter "break" code. Seen under virtualized environments such as VMware ESX. Explanations: 1) Holding down 'enter' will not set a repeating sequence of 0x1c(make)-0x9c(make), but a repeating sequence of make codes, followed by one break code when the key is released. Thus, it's wrong to expect the break code after seeing the 'enter' make code. 2) Keypad enter generates different make/break, namely 0xe0 0x1c and 0xe0 0x9c. The 'generic' logic handles the 0xe0 escape already, but the special 'enter' logic always expects '0x9c' and not '0xe0 0x9c', so you get a warning message, again. 3) When expecting the 'enter' break code, the code polls the status register in a tight loop, like so - > while ((inb(KBD_STATUS_REG) & KBD_STAT_OBF) == 0); However, it really should do something like - > while ((inb(KBD_STATUS_REG) & KBD_STAT_OBF) == 0) > cpu_relax(); /* pause */ Basically, it's a common optimization to have a fast path for accessing often accessed and slow changing I/O in a virtualized environment. The tight spinning in KDB seems to run against the logic by ESX keyboard virtualization code to detect when the fast path or the slow path should be used to satisfy the keyboard status read, leading to multi-second timeouts before the 'real' status comes through. Without knowing ESX internals, it's hard to say if this is an ESX bug or not, but letting the VM be explicitely descheduled seems to resolve the problem. I've seen something similar with shared MMIO buffers with VMs on Hyper-V. Anyway, given (3), (2) and (1), we might as well blow away the entire special casing for 'enter'. The break codes will already be handled correctly, and we get rid of the bugs with repeat enters and keypad enter key. And of course, there is no need to AND with 0x7f when checking for 'enter', because we'll never ever get to this code with a break code (checked for much earlier). Also, fix all tight inb loops to do cpu_relax(). A similar patch is being discussed with Jason Wessel for the mainline KDB. He brought up the point of stray make/break codes getting introduced (from the enter) on KDB exit, which is a problem that doesn't exist in mainline KDB (input device is reset). For LKDB, I could see that this can happen, although I haven't seen any strange behavior per se. I wanted to get some feedback before I modified kdba_local_arch_cleanup to flush the RX FIFO. Tested on ESX 5.0 and QEMU.

[opensuse-kernel] openafs-1.6 kernel-3.1.9 scheduling while atomic
by Joachim Geiger 26 Apr '12

26 Apr '12

Dear all, after upgrading from opensuse 11.4 to 12.1, I have a strange problem when using openafs (version 1.6 from the repository http://download.opensuse.org/repositories/filesystems ). After some time my pc freezes, no keyboard or mouse action is possible and in order to get the pc working again, I need to do a reset and reboot it. Inspecting the log-messages (/var/log/messages) I find a bug-entry with the line "scheduling while atomic".

Now I see in http://download.opensuse.org/repositories/Kernel:/stable/standard/i686/ there are kernel-desktop and kernel-pae, but no kernel-default, while in http://download.opensuse.org/repositories/Kernel:/stable/standard/i586/ there is only kernel-default. Other than downloading the kernel I want manually and asking zypper to install it, how does a 11.4 user from Kernel:stable get a zypper upgrade from a 32 bit kernel that finds all 4G of RAM (e.g. desktop 3.1.3) instead of only 3.5G of RAM (e.g. default 3.3.2), 'zypper in kernel-desktop-3.3.2-1.1.i686' (which I know does, but is it the right way to go about it)? If desktop is the kernel of choice, what's the difference between kernel-desktop and kernel-desktop-base? Are they exclusive, or does plain add something to what base already provides, meaning if one wants what plain has that both are needed? If my CPU supports PAE, do I want PAE kernel instead of desktop for system that is both desktop and web server? I looked for a wiki page to explain such things (site:opensuse.org kernel stable -forums; site:opensuse.org choose kernel -forums; site:opensuse.org select kernel -forums), but found none. -- "The wise are known for their understanding, and pleasant words are persuasive."

[opensuse-kernel] what does "rerouted to legacy IRQ" mean and how do I prevent it?
by Per Jessen 23 Apr '12

23 Apr '12

I'm having a few odd issues with 12.1+updates on an HP ML570G3 box. I'm pretty certain it's irq related - in 12.1 (kernel 3.1.9-1.4) the irqs for the two storage controllers and the two GigE NICs are "rerouted to legacy IRQs". In 11.4 this does not happen - what does this rerouting mean and is there a way of preventing it in 12.1? thanks -- Per Jessen, Zürich (13.6°C) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] [PATCH 1/2] acer-wmi: No wifi rfkill on Lenovo machines
by Lee, Chun-Yi 18 Apr '12

18 Apr '12

From: Ike Panhc <ike.pan(a)canonical.com> Git-commit: 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a Patch-mainline: v3.3-rc8 References: bnc#752673 Target-release: openSUSE 12.1 We have several reports which says acer-wmi is loaded on ideapads and register rfkill for wifi which can not be unblocked. Since ideapad-laptop also register rfkill for wifi and it works reliably, it will be fine acer-wmi is not going to register rfkill for wifi once VPC2004 is found. Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no wifi rfkill capability, there are reports which says acer-wmi also block wireless on Thinkpad E520/E420.
