Proposal to change .sym files

by Ge van Geldorp

In anticipation of doing some work on performance issues, I've been experimenting with our kernel profiler the last few days. For those who don't know, you can activate the profiler by including the /PROFILE option on the command line. On each timer interrupt the current EIP will be saved, after 30 sec a background task will convert the saved EIPs to function name/file name, count how often each function name occurs and write the results to a file %system_root%\profiler.log. There are 100 timer ticks per second, a 30 sec measuring interval will therefore generate 3000 EIPs. This works very nice, but I'm running into one problem on my 300MHz test machine: conversion of the EIPs to function name by the background thread takes about 60 sec. Almost all of that time is spent looking up the correct .stabs entry from the info in the .sym file. This is done using a linear search. Since there can be 100000 .stabs entries in a .sym file, going through these for each of the 3000 measurements can mean 300000000 compares. Even worse, two passes are made through the .stabs list for each measurement, one to find the function name and one to find the file name. No wonder this takes 60 sec. So, we need to improve the search. I've done some simulations, and when I use a binary search instead of a linear search, the performance is dramatically better. Time required to convert all measurements drops from 60 sec to 0.06 sec, a 1000 fold improvement. To be able to use a binary search, the information in the .sym file needs to be sorted and uniform (each element contains the same type of data) which it currently isn't. We have .stabs entries defining a function (N_FUN), source line (N_SLINE) and source file (N_SO). Currently, we only use the .sym files to convert an address to function name/file name/source line, not the other way around (no function name to address for example). I'd like to drop using the .stab format in the .sym files and change to the following format: +----------+ |header | +----------+ |symentries| +----------+ |strings | +----------+ The header would just contain the start location and number of symentries plus start location and total size of the strings. Each symentry would have the following info: typedef struct tagSYM_ENTRY { ULONG_PTR Address; ULONG FunctionOffset; ULONG FileOffset; ULONG SourceLine; } SYM_ENTRY, *PSYM_ENTRY; where Address is an address relative to the beginning of the module, FunctionOffset and FileOffset are offsets from the beginning of the strings section and SourceLine contains the source line number. The symentries are sorted by Address (done by rsym). Each Address would only appear once, and information would be made as complete as possible (e.g. when creating the symentries from the .stabs in the .nostrip.exe file each FunctionOffset would be set to point to the function name from the most recently encountered N_FUN .stab). This will allow us to retrieve all 3 pieces of information (function name, file name and source line) by doing just a single binary search. Comments, thoughts, objections? Gé van Geldorp.

ReactOS DOS subsystem

by AzeemArif

Hello ROS-Devs, I've been sharing some thoughts about DOS subsystem on ReactOS forum. I am pasting my last post (http://reactos.com/forum/viewtopic.php?p=2864#2864 ) <http://reactos.com/forum/viewtopic.php?p=2864#2864> here for your comments ======================================================== hello, I am back with my silly posts Smile But this time, after seriously reading and experimenting with FreeDos and DosEmu code. As many people suggested FreeDOS as an option to run as ReactOS subsystem, I concentrated more on FreeDOS. Something I came to know are 1) We need ReactOS DOS/Win16 subsystem so that we can run 16bit DOS applications on ReactOS. 2) FreeDOS itself is 16bit system 3) Compiling FreeDOS code with 32bit compiler is so difficult that it gave birth to a new project FreeDOS-32 (I tried compiling FreeDOS code with MinGW with no success) 4) FreeDOS-32 is in its infancy. Currently it can't even run simple DOS applications 5) DOSEmu is really slow Please give your valuable suggestions. AcetoliNe: I agree with your last post. ===================================================================== ~AzeemArif (ReactOS IRC channel - "azar")

RE: [ros-dev] msvcrt/crtdll "merge"

by Waldo Alvarez Cañizares

Hi Gunnar: >And about the strlen=ntdll.strlen stuff. Forwarded functions doesnt show >up as imported because they arent really imported, so this is normal. I think that it is not normal. The better way should be to really forward them, this is just half baked stuff. If you are not going to forward it, I think that it would be better to not declare them as such because that can cause confusion. >Dont understand what XP's ntdll exporting "WindowsCE" functions has to >do with anything? Was just a comment about ntdll, they are exported and nothing is mentioned in msdn. I said that because I think ntdll is very close to the runtime. Best Regards Waldo
