* sh: Clock framework tidying.Paul Mundt2006-12-061-3/+3
| | | | | | | | This syncs up the SH clock framework with the linux/clk.h API, for which there were only some minor changes required, namely the clk_get() dev_id and subsequent callsites. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: More flexible + SH7780 earlyprintk SCIF support.Paul Mundt2006-12-061-0/+1
| | | | | | | | | | | This makes the early printk support somewhat more flexible, moving the port definition to a config option, and making the port initialization configurable for sh-ipl+g users. At the same time, this allows us to trivially wire up the SH7780 SCIF0, so that's thrown in too more or less for free. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* [PATCH] remote memory corruptor in ibmtr.cAl Viro2006-12-041-1/+1
| | | | | | | | | | | ip_summed changes last summer had missed that one. As the result, we have ip_summed interpreted as CHECKSUM_PARTIAL now. IOW, ->csum is interpreted as offset of checksum in the packet. net/core/* will both read and modify the value as that offset, with obvious reasons. At the very least it's a remote memory corruptor.

| * [POWERPC] ps3: multiplatform build fixesArnd Bergmann2006-12-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

| * [POWERPC] Souped-up of_platform_device supportBenjamin Herrenschmidt2006-12-045-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch first splits of_device.c and of_platform.c, the later containing the bits relative to of_platform_device's. On the "breaks" side of things, drivers uisng of_platform_device(s) need to include asm/of_platform.h now and of_(un)register_driver is now of_(un)register_platform_driver. In addition to a few utility functions to locate of_platform_device(s), the main new addition is of_platform_bus_probe() which allows the platform code to trigger an automatic creation of of_platform_devices for a whole tree of devices. The function acts based on the type of the various "parent" devices encountered from a provided root, using either a default known list of bus types that can be "probed" or a passed-in list. It will only register devices on busses matching that list, which mean that typically, it will not register PCI devices, as expected (since they will be picked up by the PCI layer). This will be used by Cell platforms using 4xx-type IOs in the Axon bridge and can be used by any embedded-type device as well.

Failure to correct this value on non-x86 machines makes drive detection prone to failure due to timeouts. (I've observed about 50% detection failure rates on SPARC64.) The HW boots with a bad value in this register, but on x86 machines the Promise BIOS corrects it to the value recommended by the manual, so most people have been unaffected by this issue. After developing the patch I checked Promise's SATAII driver, and discovered that it also corrects PHYMODE4 just like this patch does. This patch depends on the sata_promise SATAII updates patch I sent recently. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * | | [PATCH] libata: always use polling IDENTIFYTejun Heo2006-12-034-14/+4

This has caused a lot of problems including device misdetection and phantom device. ATA_FLAG_DETECT_POLLING was added recently to selectively use polling IDENTIFY on problemetic drivers but many controllers and devices are affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING for each such case is diffcult and not very rewarding. This patch makes libata always use polling IDENTIFY. This is consistent with libata's original behavior and drivers/ide's behavior.

In turn, ahci_deinit_port() invokes ahci_power_down() to power down the port. If the controller supports slumber mode, the link is put into it. Unfortunately, some devices don't implement link powersaving mode properly and show erratic behavior after link is put into slumber mode. For example, HL-DT-ST DVD-RAM GSA-H30N completely locks up on slumber transition and can only be recovered with the *REAL* hard reset - power removal and reapply. Note that this makes the first probing reset different from all others. If the above dvd-ram is hotplugged after ahci is initialized, no problem occurs because ahci is already fully initialized with phy powered up. So, this might also be the reason for other weird AHCI initial probing abnormalities. This patch moves power up/down out of port init/deinit and call them only when needed. Power down is now called only when suspending. As system suspend usually involves powering down 12v for storage devices, this shouldn't cause problem even if the attached device doesn't support slumber mode. However, in partial power management and suspend failure cases, devices might lock up after suspend attempt. I thought about removing transition to slumber mode altogether but ahci spec mandates it before HBA D3 state transition. Blacklisting such devices might be the solution.

Under certain circumstances, some controllers (ICH7 in enhanced mode w/ IRQ shared) raise IRQ when CTL register is written to and ATA_NIEN doesn't mask it. This patch makes ata_bmdma_freeze() clear all pending IRQs after freezing a port. This change makes explicit clearing in ata_device_add() unnecessary and thus kills it. The removed code was SFF-specific and was in the wrong place. Note that ->freeze() handler is always called under ap->lock held and irq disabled. Even if CTL manipulation causes stuck IRQ, it's cleared immediately. This should be safe (enough) even in SMP environment. More correct solution is to mask the IRQ from IRQ controller but that would be an overkill. Signed-off-by: Tejun Heo <htejun@gmail.com>

| * | | [PATCH] sata_nv: fix ATAPI in ADMA modeRobert Hancock2006-12-011-130/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv with ATAPI devices on controllers running in ADMA mode. Some of the logic in the nv_adma_bmdma_* functions was inverted causing a bunch of warnings and caused those functions not to work properly. Also, when an ATAPI device is connected, we need to use the legacy DMA engine. The code now disables the PCI configuration register bits for ADMA so that this works, and ensures that no ATAPI DMA commands go through until this is done.

The ATA driver also has to do some work however when resuming from RAM. Certain chips need the FIFO reconfiguring, and the 66MHz clock setup updating.
