From 793b883ed12a6ae6e2901ddb5e038b77d6f0c0ac Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 14 Sep 2005 16:06:14 -0700 Subject: [PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ.

Today the answer is: It depends. On i386: SMP kernel - It is always the boot frequency UP kernel - Scales with the frequency change and shows that was last set. On x86_64: There is one single variable cpu_khz that gets written by all the CPUs. So, the frequency set by last CPU will be seen on /proc/cpuinfo of all the CPUs in the system. What you see also depends on whether you have constant_tsc capable CPU or not. On ia64: It is always boot time frequency of a particular CPU that gets displayed. The patch below changes this to: Show the last known frequency of the particular CPU, when cpufreq is present. If cpu doesnot support changing of frequency through cpufreq, then boot frequency will be shown. The patch affects i386, x86_64 and ia64 architectures.

This means, that before freeing reiser4-specific portion of super-block (during umount) we have to wait until all pending RCU callbacks are executed.

Whenever you switch from X to a framebuffer console for the very first time, there is a chance that a broken X system has _not_ set the mode to KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and several other functions before a set_par() is executed. This is believed to be not a bug of linux but a bug of X/xdm. At least some X releases used by SuSE and Debian show this behaviour. There was a 2nd case, but that has been fixed by Antonino Daplas on 10-dec-2005. This patch allows drivers to set a flag to inform fbcon_switch() that they prefer a set_par() call on every console switch, working around the problems caused by the broken X releases. The flag will be used by the next release of cyblafb and might help other drivers that assume a hardware state different to the one used by X. As the default behaviour does not change, this patch should be acceptable to everybody. Signed-off-by: Knut Petersen Acked-by: "Antonino A.

Previously, this was done by each user by manually initializing a qc, issueing it, waiting for its completion and handling errors. In addition to obvious code factoring, using ata_exec_internal() fixes the following bugs. * qc not freed on issue failure * ap->qactive clearing could race with the next internal command * race between timeout handling and irq * ignoring error condition not represented in tf->status Also, qc & hardware are not accessed anymore once it's completed, making internal commands more conformant with general semantics. ata_exec_internal() also makes it easy to issue internal commands from multiple threads if that becomes necessary. This patch only implements ata_exec_internal(). A following patch will convert all users. Signed-off-by: Tejun Heo -- Jeff, all patches have been regenerated against upstream branch as of today. (575ab52a218e4ff0667a6cbd972c3af443ee8713) Also, I took out a debug printk from ata_exec_internal (don't know how that one got left there).
