x86: i386-show-unhandled-signals-v3

2007-07-22T18:03:37+00:00

This patch makes the i386 behave the same way that x86_64 does when a segfault happens. A line gets printed to the kernel log so that tools that need to check for failures can behave more uniformly between debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 > /proc/sys/debug/exception-trace) Also, all of the lines being printed are now using printk_ratelimit() to deny the ability of DoS from a local user with a program like the following: main() { while (1) if (!fork()) *(int *)0 = 0; } This new revision also includes the fix that Andrew did which got rid of new sysctl that was added to the system in earlier versions of this. Also, 'show-unhandled-signals' sysctl has been renamed back to the old 'exception-trace' to avoid breakage of people's scripts. AK: Enabling by default for i386 will be likely controversal, but let's see what happens AK: Really folks, before complaining just fix your segfaults AK: I bet this will find a lot of silent issues Signed-off-by: Masoud Sharbiani Signed-off-by: Andi Kleen [ Personally, I've found the complaints useful on x86-64, so I'm all for this. That said, I wonder if we could do it more prettily.. -Linus ] Signed-off-by: Linus Torvalds

x86_64: disable the GART in shutdown

2007-07-22T01:37:13+00:00

For K8 system: 4G RAM with memory hole remapping enabled, or more than 4G RAM installed. when using kexec to load second kernel. In the second kernel, when mem is allocated for GART, it will do the memset for clear, it will cause restart, because some device still used that for dma. solution will be: in second kernel: disable that at first before we try to allocate mem for it. or in the first kernel: do disable that before shutdown. Andi/Eric/Alan prefer to second one for clean shutdown in first kernel. Andi also point out need to consider to AGP enable but mem less 4G case too.

[PATCH] x86: Don't use MWAIT on AMD Family 10

2007-05-02T17:27:12+00:00

It doesn't put the CPU into deeper sleep states, so it's better to use the standard idle loop to save power. But allow to reenable it anyways for benchmarking. I also removed the obsolete idle=halt on i386 Cc: andreas.herrmann@amd.com Signed-off-by: Andi Kleen

[PATCH] x86-64: Remove the identity mapping as early as possible

2007-05-02T17:27:07+00:00

With the rewrite of the SMP trampoline and the early page allocator there is nothing that needs identity mapped pages, once we start executing C code. So add zap_identity_mappings into head64.c and remove zap_low_mappings() from much later in the code. The functions are subtly different thus the name change. This also kills boot_level4_pgt which was from an earlier attempt to move the identity mappings as early as possible, and is now no longer needed. Essentially I have replaced boot_level4_pgt with trampoline_level4_pgt in trampoline.S Signed-off-by: Eric W. Biederman Signed-off-by: Vivek Goyal Signed-off-by: Andi Kleen
