From b111757c50ee30dad162192df6168e270a90c252 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 19 Jul 2007 01:48:14 -0700 Subject: arch: personality independent stack top New arch macro STACK_TOP_MAX it gives the larges valid stack address for the architecture in question. It differs from STACK_TOP in that it will not distinguish between personalities but will always return the largest possible address. This is used to create the initial stack on execve, which we will move down to the proper location once the binfmt code has figured out where that is.

Miller" Date: Fri, 20 Jul 2007 16:59:26 -0700 Subject: [SPARC]: Fix serial console device detection. The current scheme works on static interpretation of text names, which is wrong. The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.

Basically, we just make sure that for every system device we create, the dev->archdata 'iommu' and 'stc' fields are filled in. Then we have two platform variants of the DMA ops, one for SUN4U which actually programs the real hardware, and one for SUN4V which makes hypervisor calls.

Miller" Date: Thu, 16 Aug 2007 22:59:49 -0700 Subject: [MATH-EMU]: Fix underflow exception reporting. The underflow exception cases were wrong. This is one weird area of ieee1754 handling in that the underflow behavior changes based upon whether underflow is enabled in the trap enable mask of the FPU control register. As a specific case the Sparc V9 manual gives us the following description: -------------------- If UFM = 0: Underflow occurs if a nonzero result is tiny and a loss of accuracy occurs. Tininess may be detected before or after rounding. Loss of accuracy may be either a denormalization loss or an inexact result. If UFM = 1: Underflow occurs if a nonzero result is tiny. Tininess may be detected before or after rounding. -------------------- What this amounts to in the packing case is if we go subnormal, we set underflow if any of the following are true: 1) rounding sets inexact 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too 3) underflow is set in FPU control register trap-enable mask The initially discovered example was "DBL_MIN / 16.0" which incorrectly generated an underflow. It should not, unless underflow is set in the trap-enable mask of the FPU csr. Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. However, if underflow is set in the trap enable mask, only underflow should be set and reported as a trap. That is handled properly by the prioritization logic in arch/sparc{,64}/math-emu/math.c:record_exception(). Based upon a report and test case from Jakub Jelinek. Signed-off-by: David S.
