* [PATCH] Update cyblafb driverKnut Petersen2006-01-092-650/+875
| | | | | | | | | | | | | | | | | | | | | | | | | This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] sata_nv, spurious interrupts at system startup with MAXTOR 6H500F0 driveAndrew Chew2006-01-091-6/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works around a problem with spurious interrupts seen at boot time when a MAXTOR 6H500F0 drive is present. An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects some corner cases in managing the RAE/RRE bits in the mthca qp context. These bits need to be zero if the user requests max_dest_rd_atomic of zero. The bits need to be restored to the value implied by the qp access flags attribute in a previous (or the current) modify-qp command if the dest_rd_atomic variable is changed to non-zero. In the current implementation, the following scenario will not work: RESET-to-INIT set QP access flags to all disabled (zeroes) INIT-to-RTR set max_dest_rd_atomic=10, AND set qp_access_flags = IB_ACCESS_REMOTE_READ | IB_ACCESS_REMOTE_ATOMIC The current code will incorrectly take the access-flags value set in the RESET-to-INIT transition. We can simplify, and correct, this IB_QP_ACCESS_FLAGS handling: it is always safe to set qp access flags in the firmware command if either of IB_QP_MAX_DEST_RD_ATOMIC or IB_QP_ACCESS_FLAGS is set, so let's just set it to the correct value, always.
