| | | | | | | | | | | | | | | | | | Currently spitz_ohci_init() that requests GPIO doesn't have corresponding spitz_ohci_exit() which will gpio_free(). This causes minor problems e.g. during resume when the OHCI device can't be resumed. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>
| * [ARM] pxa: enable GPIO receivers after configuring pinsTimothy Clacy2009-05-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 'mach-pxa' platforms currently rely on a bootloader to setup GPIO pins and clear RDH (to enable inputs). A kernel loaded by a 'minimal' bootloader, that doesn't touch any pins, will not function correctly; inputs will remain disabled, even after the pins are configured. The following change fixes the issue and has been verified on Gumstix Verdex XL6P and a custom PXA270 platform.

The failure scenario in the kexec case is the following: * Assume a PCI device is not power-manageable by the platform and has PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR. * The device is put into D3 before kexec (using the native PCI PM). * After kexec, pci_setup_device() sets the device's power state to PCI_UNKNOWN. * pci_set_power_state(dev, PCI_D0) is called by the device's driver. * __pci_start_power_transition(dev, PCI_D0) is called and since the device is not power-manageable by the platform, it causes pci_update_current_state(dev, PCI_D0) to be called. As a result the device's current_state field is updated to PCI_D3, in accordance with the contents of its PCI PM registers. * pci_raw_set_power_state() is called and it changes the device power state to D0. *However*, it should also call pci_restore_bars() to reinitialize the device, but it doesn't, because the device's current_state field has been modified earlier. To prevent this from happening, modify pci_platform_power_transition() so that it doesn't use pci_update_current_state() to update the current_state field for devices that aren't power-manageable by the platform. Instead, this field should be updated directly for devices that don't support the native PCI PM. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

This could cause the X server to hang in drmWaitVBlank(). Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more. For consistency I also modified tlb-r3k.c even though that file is only used on 32-bit.] Signed-off-by: Greg Ungerer <gerg@snapgear.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
