2006-10-11[PATCH] libata: return sense data in HDIO_DRIVE_CMD ioctlEran Tromer1-7/+39
Make the HDIO_DRIVE_CMD ioctl in libata (ATA command pass through) return a few ATA registers to userspace, following the same convention as the drivers/ide implementation of the same ioctl. This is needed to support ATA commands like CHECK POWER MODE, which return information in nsectors. This fixes "hdparm -C" on SATA drives. Forcing the sense data read via the cc flag causes spurious check conditions, so we filter these out (following the ATA command pass-through specification T10/04-262r7).

2006-10-11[PATCH] sky2: set lower pause threshold to prevent overrunStephen Hemminger1-1/+1

2006-10-11[PATCH] sky2: revert pci express extensionsStephen Hemminger2-24/+51
The pci express error handling extensions don't work unless PCI access is via mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail. Since the sky2 driver has other ways of getting to PCI config space, it works around this short coming, but the pci_find_ext_capablity doesn't work. This backs out commit 91aeb3edbcf4e6ed72d138ac8c22fd68e6d717c3 Go back to hardcoding, since we know where the error registers are anyway.

2006-10-11[PATCH] powerpc/cell spidernet reduce DMA kickingLinas Vepstas1-6/+13
The current code attempts to start the TX dma every time a packet is queued. This is too conservative, and wastes CPU time. This patch changes behaviour to call the kick-dma function less often, only when the tx queue is at risk of emptying. This reduces cpu usage, improves performance.

2006-10-11[PATCH] powerpc/cell spidernet refine lockingLinas Vepstas1-52/+43
The transmit side of the spider ethernet driver currently places locks around some very large chunks of code. This results in a fair amount of lock contention is some cases. This patch makes the locks much more fine-grained, protecting only the cirtical sections. One lock is used to protect three locations: the queue head and tail pointers, and the queue low-watermark location.

2006-10-11[PATCH] powerpc/cell spidernet low watermark patch.Linas Vepstas2-4/+47
Implement basic low-watermark support for the transmit queue. Hardware low-watermarks allow a properly configured kernel to continously stream data to a device and not have to handle any interrupts at all in doing so. Correct zero-interrupt operation can be actually observed for this driver, when the socket buffer is made large enough. The basic idea of a low-watermark interrupt is as follows. The device driver queues up a bunch of packets for the hardware to transmit, and then kicks the hardware to get it started. As the hardware drains the queue of pending, untransmitted packets, the device driver will want to know when the queue is almost empty, so that it can queue some more packets. If the queue drains down to the low waterark, then an interrupt will be generated. However, if the kernel/driver continues to add enough packets to keep the queue partially filled, no interrupt will actually be generated, and the hardware can continue streaming packets indefinitely in this mode. The impelmentation is done by setting the DESCR_TXDESFLG flag in one of the packets. When the hardware sees this flag, it will interrupt the device driver. Because this flag is on a fixed packet, rather than at fixed location in the queue, the code below needs to move the flag as more packets are queued up. This implementation attempts to keep the flag at about 1/4 from "empty".

2006-10-11[PATCH] b44: fix eeprom endianess issueMichael Buesch1-1/+1
This fixes eeprom read on big-endian architectures. readw returns the data in CPU order. With cpu_to_le16 we convert it to little endian, because "ptr" is a pointer to a _byte_ arrray. See the cast above. A byte array is little endian. The bug is: Reading u16 values with readw, casting them into an u8 array and accessing this u8 array as an u8 (byte) array. The correct fix is to swap the CPU-ordering value returned by readw into little endian, as the u8 array is little endian. This compiles to nothing on little endian hardware (so it does not change b44 code on LE hardware), but _fixes_ code on BE hardware.
