2010-07-26ide/atapi: add support for GET EVENT STATUS NOTIFICATIONAurelien Jarno1-0/+15
The GET EVENT STATUS NOTIFICATION is a mandatory command according to MMC-3, even if event status notification is not supported. This patch adds support for this command. It returns NEA ("No Event Available") with an empty "Supported Event Classes" to show that it doesn't event support status notification. If asychronous operation is requested, which requires NCQ support, it returns an error according to the specifications. This fixes HAL support on FreeBSD and derivatives, which fill up the logs every second with: acd0: FAILURE - unknown CMD (0x03) ILLEGAL REQUEST asc=0x20 ascq=0x00 Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-07-24mips: Correct MIPS interrupt glue logic for icountEdgar E. Iglesias1-17/+6
When hw interrupt pending bits in CP0_Cause are set, the CPU should see the hw interrupt line as active. The CPU may or may not take the interrupt based on internal state (global irq mask etc) but the glue logic shouldn't care. This fixes MIPS external hw interrupts in combination with -icount.

2010-07-22scsi: Dequeue requests before invoking completion callbackJan Kiszka2-1/+12
The request completion callback of the LSI controller may start the next request that can use the same tag as the completed one. As the latter is still enqueued at that point, scsi_send_command will complain about the tag reuse and cancel the completed request. That will cause a double free later on when the completion path cleans up as well. Fix this by dequeuing the request before invoking the callback.

2010-07-22e1000: Fix wrong microwire EEPROM state initializationIzumi Tsutsui1-9/+8
This change fixes initialization of e1000's microwire EEPROM internal state values so that qemu's e1000 emulation works on NetBSD, which doesn't use Intel's em driver but has its own wm driver for the Intel i8254x Gigabit Ethernet. Previously set_eecd() function in e1000.c clears EEPROM internal state values on SK rising edge during CS==L, but according to FM93C06 EEPROM (which is MicroWire compatible) data sheet, EEPROM internal status should be cleared on CS rise edge regardless of SK input: "... a rising edge on this (CS) signal is required to reset the internal state-machine to accept a new cycle .." and nothing should be changed during CS (chip select) is inactive. Intel's em driver seems to explicitly raise SK output after CS is negated in em_standby_eeprom() so many other OSes that use Intel's driver don't have this problem even on the previous e1000.c implementation, but I can't find any articles that say the MICROWIRE or EEPROM spec requires such sequence, and actually hardware works fine without it (i.e. real i82540EM has been working on NetBSD). This fix also changes initialization to clear each state value in struct eecd_state individually rather than using memset() against the whole structre. The old_eecd member stores the last SK and CS signal levels and it should be preserved even after reset of internal EEPROM state to detect next signal edges for proper EEPROM emulation.
