[PATCH] x86-64: Fix incorrect FP signals · ff347b22

由 Chuck Ebbert 提交于 9月 12, 2005

This is the same patch that went into i386 just before 2.6.13
came out.  I still can't build 64-bit user apps, so I tested
with program (see below) in 32-bit mode on 64-bit kernel:

Before:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown]
	handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
	handler: i387 unmasked precision exception, rounded up

After:

	$ fpsig
	handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10
	handler: altstack is at 0x0804b000, ebp = 0x0804bc7c
	handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result]
	handler: fpu cwd = 0xb40, fpu swd = 0xbaa0
	handler: i387 unmasked precision exception, rounded up

[PATCH] x86-64: Make remote TLB flush more scalable · e5bc8b6b

由 Andi Kleen 提交于 9月 12, 2005

Instead of using a global spinlock to protect the state
of the remote TLB flush use a lock and state for each sending CPU.

To tell the receiver where to look for the state use 8 different
call vectors.  Each CPU uses a specific vector to trigger flushes on other
CPUs. Depending on the received vector the target CPUs look into
the right per cpu variable for the flush data.

When the system has more than 8 CPUs they are hashed to the 8 available
vectors. The limited global vector space forces us to this right now.
In future when interrupts are split into per CPU domains this could be
fixed, at the cost of needing more IPIs in flat mode.

Also some minor cleanup in the smp flush code and remove some outdated
debug code.

Requires patch to move cpu_possible_map setup earlier.

[PATCH] x86-64: Support dualcore and 8 socket systems in k8 fallback node parsing · 3f098c26

由 Andi Kleen 提交于 9月 12, 2005

In particular on systems where the local APIC space and node space
is very different from the Linux CPU number space.

Previously the older NUMA setup code directly parsing the K8
northbridge registers had some issues on 8 socket or dual core
systems. This patch fixes them.

This is mainly done by fixing some confusion between Linux
CPU numbers and local APIC ids. We now pass the local APIC IDs
to later code, which avoids mismatches.

Also add some heuristics to detect cases where the Hypertransport
nodeids and the local APIC IDs don't match, but are shifted
by a constant offset.

This is still all quite hackish, hopefully BIOS writers fill
in correct SRATs instead.
