2008-10-22math-emu: Fix signalling of underflow and inexact while packing result.Kumar Gala
I'm trying to move the powerpc math-emu code to use the include/math-emu bits. In doing so I've been using TestFloat to see how good or bad we are doing. For the most part the current math-emu code that PPC uses has a number of issues that the code in include/math-emu seems to solve (plus bugs we've had for ever that no one every realized). Anyways, I've come across a case that we are flagging underflow and inexact because we think we have a denormalized result from a double precision divide: 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE soft: 001.0000000000000 ..... syst: 001.0000000000000 ...ux What it looks like is the results out of FP_DIV_D are: D: sign: 0 mantissa: 01000000 00000000 exp: -1023 (0) The problem seems like we aren't normalizing the result and bumping the exp. Now that I'm digging into this a bit I'm thinking my issue has to do with the fix DaveM put in place from back in Aug 2007 (commit 405849610fd96b4f34cd1875c4c033228fea6c0f): [MATH-EMU]: Fix underflow exception reporting. 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 ... 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. Here is the distilled glibc test case from Jakub Jelinek which prompted that commit: -------------------- #include <float.h> #include <fenv.h> #include <stdio.h> volatile double d = DBL_MIN; volatile double e = 0x0.0000000000001p-1022; volatile double f = 16.0; int main (void) { printf ("%x\n", fetestexcept (FE_UNDERFLOW)); d /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); e /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); return 0; } -------------------- It looks like the case I have we are exact before rounding, but think it looks like the rounding case since it appears as if "overflow is set". 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE = 001.0000000000000 I think the following adds the check for my case and still works for the issue your commit was trying to resolve.

2008-10-22sparc: correct section of current_pc()Frederic Weisbecker
Latest mainline gives this section mismatch on sparc: The function current_pc() references the variable __init no_sun4u_here. This is often because current_pc lacks a __init annotation or the annotation of no_sun4u_here is wrong. Since current_pc() is used only in early time, it is correct to put it in .init section.

2008-10-22sparc: correct section of apc_no_idleFrederic Weisbecker
The latest mainline gives this section mismatch on sparc: The function __devinit apc_probe() references a variable __initdata apc_no_idle. If apc_no_idle is only used by apc_probe then annotate apc_no_idle with a matching annotation. Since the commit 7e7e2f035663c5ceb029bfb9d91e75099b0a5625, apc_probe() is on __devinit so we have to correct apc_no_idle which is referenced by this function.

Make the special case be a nice inlien function of its own, clean up the code, and make the warning go away. I wish people didn't write code that gets (valid) warnings from the compiler, but I'll limit my fixes to code that I actually care about (in this case just because I see the warning and it annoys me).

2008-10-20PCI: introduce an pci_ioremap(pdev, barnr) functionArjan van de Ven
A common thing in many PCI drivers is to ioremap() an entire bar. This is a slightly fragile thing right now, needing both an address and a size, and many driver writers do.. various things there. This patch introduces an pci_ioremap() function taking just a PCI device struct and the bar number as arguments, and figures this all out itself, in one place. In addition, we can add various sanity checks to this function (the patch already checks to make sure that the bar in question really is a MEM bar; few to no drivers do that sort of thing). Hopefully with this type of API we get less chance of mistakes in drivers with ioremap() operations.

This patch adds support for PCI Express Alternative Routing-ID Interpretation (ARI) capability. The ARI capability extends the Function Number field of the PCI Express Endpoint by reusing the Device Number which is otherwise hardwired to 0. With ARI, an Endpoint can have up to 256 functions.

2008-10-20PCI: centralize the capabilities code in probe.cZhao, Yu
This patch centralizes the initialization and release functions of various PCI capabilities in probe.c, which makes the introduction of new capability support functions cleaner in the future. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2008-10-20PCI: centralize the capabilities code in pci-sysfs.cZhao, Yu
This patch centralizes functions used to add and remove sysfs entries for various capabilities. With this cleanup, the code is more readable and easier for adding new capability related functions. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2008-10-20PCI: fix 64-vbit prefetchable memory resource BARsPeter Chubb
Since patch 6ac665c63dcac8fcec534a1d224ecbb8b867ad59 my infiniband controller hasn't worked. This is because it has 64-bit prefetchable memory, which was mistakenly being taken to be 32-bit memory. The resource flags in this case are PCI_BASE_ADDRESS_MEM_TYPE_64 | PCI_BASE_ADDRESS_MEM_PREFETCH. This patch checks only for the PCI_BASE_ADDRESS_MEM_TYPE_64 bit; thus whether the region is prefetchable or not is ignored. This fixes my Infiniband.

2008-10-20PCI: replace cfg space size (256/4096) by macros.Zhao, Yu
This is a cleanup that changes all PCI configuration space size representations to the macros (PCI_CFG_SPACE_SIZE and PCI_CFG_SPACE_EXP_SIZE). And the macros are also moved from drivers/pci/probe.c to drivers/pci/pci.h. Signed-off-by: Yu Zhao <yu.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
