* Hibernation: New testing facility (rev. 2)Rafael J. Wysocki2008-02-012-15/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to test the hibernation core code with the help of the /sys/power/pm_test attribute introduced for suspend testing in the previous patch. Writing an appropriate string to this file causes the hibernation code to work in one of the test modes defined as follows: freezer - test the freezing of processes devices - test the freezing of processes and suspending of devices platform - test the freezing of processes, suspending of devices and platform global   control methods(*) processors - test the freezing of processes, suspending of devices, platform global   control methods(*) and the disabling of nonboot CPUs core - test the freezing of processes, suspending of devices, platform global   control methods(*), the disabling of nonboot CPUs and suspending of   platform/system devices (*) - the platform global control methods are only available on ACPI systems       and are only tested if the hibernation mode is set to "platform" Then, if a hibernation is started by normal means, the hibernation core will perform its normal operations up to the point indicated by given test level. Next, it will wait for 5 seconds and carry out the resume operations needed to transition the system back to the fully functional state. Signed-off-by: Rafael J.

* Suspend: Testing facility (rev. 2)Rafael J. Wysocki2008-02-012-9/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce sysfs attribute /sys/power/pm_test allowing one to test the suspend core code.  Namely, writing one of the strings: freezer devices platform processors core to this file causes the suspend code to work in one of the test modes defined as follows: freezer - test the freezing of processes devices - test the freezing of processes and suspending of devices platform - test the freezing of processes, suspending of devices and platform global   control methods(*) processors - test the freezing of processes, suspending of devices, platform global   control methods and the disabling of nonboot CPUs core - test the freezing of processes, suspending of devices, platform global   control methods, the disabling of nonboot CPUs and suspending of   platform/system devices (*) These are ACPI global control methods on ACPI systems Then, if a suspend is started by normal means, the suspend core will perform its normal operations up to the point indicated by given test level.  Next, it will wait for 5 seconds and carry out the resume operations needed to transition the system back to the fully functional state. Writing "none" to /sys/power/pm_test turns the testing off. When open for reading, /sys/power/pm_test contains a space-separated list of all available tests (including "none" that represents the normal functionality) in which the current test level is indicated by square brackets.

* Hibernation: Rework platform support ioctls (rev. 2)Rafael J. Wysocki2008-02-013-34/+38
| | | | | | | | | | | | | | | Modify the hibernation userland interface by adding two new ioctls to it, SNAPSHOT_PLATFORM_SUPPORT and SNAPSHOT_POWER_OFF, that can be used, respectively, to switch the hibernation platform support on/off and to make the kernel transition the system to the hibernation state (eg. ACPI S4) using the platform (eg. ACPI) driver. These ioctls are intended to replace the misdesigned SNAPSHOT_PMOPS ioctl, which from now is regarded as obsolete and will be removed in the future.

| * amd74xx: remove amd_ide_chips tableBartlomiej Zolnierkiewicz2008-02-011-151/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove no longer needed assertion from amd74xx_probe(). * Factor out cable detection for AMD7409 to amd7409_cable_detect() and for chipsets >= AMD7411 to amd7411_cable_detect(). * Use dev->vendor and dev->device instead of amd_config->udma_mask when selecting cable detection method and checking for broken FIFO support in init_chipset_amd74xx(). * Remove no longer needed AMD_BAD_FIFO define. * Add 'swdma' parameter for setting .swdma_mask to DECLARE_AMD_DEV() macro. * Add 'udma' parameter for setting .udma_mask to DECLARE_{AMD,NV}_DEV() macro. * Keep a copy of a current amd74xx_chipsets[] entry in amd74xx_probe() in order to fix ->swdma_mask on early AMD7409 revisions and ->udma_mask on Serenade mainboards. * Remove no longer needed fixups from init_chipset_amd74xx() and AMD_CHECK_{SWDMA,SERENADE} defines. * Move printing banner message from init_chipset_amd74xx() to amd74xx_probe(), also remove incorrect comment while at it. * Use hwif->ultra_mask instead of amd_config->udma_mask in amd_set_drive(). * Add 'udma_mask' argument to amd_set_speed() and pass UDMA mask from amd_set_drive() instead of using amd_config->udma_mask. * Move amd_config->base from AMD_* defines to users of these defines and add 0x40 the defined values. Then add amd_offset() inline helper for selecting offset from 0x40 base (needed for nVidia controllers) and finally use it in amd_set_speed(), amd7411_cable_detect() and init_chipset_amd74xx() instead of amd_config->base. * Remove no longer needed AMD_BAD_SWDMA define, ->{swdma,ultra}_mask setup from init_hwif_amd74xx(), amd_{config,chipset} variables and amd_ide_chips table. * Fix init_chipset_amd74xx() comment. * Bump driver version. There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
| * ide: ide_setup_dma() assumes 8 portsSergei Shtylyov2008-02-016-26/+26
| | | | | | | | | | | | | | | | | | According to http://marc.info/?l=linux-ide&m=114346138611631, the drivers must always register 8 DMA ports with ide_setup_dma(), so its last argument is not needed. While at it, kill some useless parens in that function... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | The TRM-290 chip is *not* SFF-8038i compatible and therefore can *not* call ide_setup_dma() -- fix this and also cleanup the code a bit... Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
