| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The config ROM buffer received from generate_config_rom is a globally shared static buffer. Extend the card_mutex protection in fw_add_card until after the config ROM was copied into the card driver's buffer. Otherwise, parallelized card driver probes may end up with ROM contents that were meant for a different card. firewire-ohci's card->driver->enable hook is safe to be called within the card_mutex. Furthermore, it is safe to reorder card_list update versus card enable, which simplifies the code a little. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

Fix the mask accordingly. The previously too large mask didn't do damage though because the next few bits in the register are reserved and therefore zero with presently existing hardware. Also, check for the maximum possible self ID count of 252 (according to OHCI 1.1 clause 11.2 and IEEE 1394a-2000 clause 4.3.4.1, i.e. up to four self IDs of up to 63 nodes, even though IEEE 1394 up to edition 2008 defines only up to three self IDs per node). More than 252 self IDs would only happen if the self ID receive DMA unit malfunctioned, which would likely be caught by other self ID buffer checks. However, check it early to be sure. More than 253 quadlets would overflow the Topology Map CSR. Reported-By: PaX Team Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

(eg. the PCI MCFG) using sfi_acpi_table_parse(). Note that this is _not_ a hybrid ACPI + SFI mode. The platform boots in either ACPI mode or SFI mode. SFI runs only with acpi_disabled=1, which can be set at build-time via CONFIG_ACPI=n, or at boot time by the failure to find ACPI platform support. So this extension simply allows SFI-platforms to re-use existing standard table formats that happen to be defined to live in ACPI envelopes.

| * | | | | | | ACPI: don't pass handle for fixed hardware notificationsBjorn Helgaas2009-09-191-1/+2

This patch consolidates those two functions and uses a flag in the struct acpi_os_dpc to determine whether to do the wait.
