I *think* this is only for AGP memory. I have a suspicion that the X server may also generate handles for the registers and/or the framebuffer by reading the device's PCI bus address registers, but I would need to verify that. This is totally broken behavior. It is very poor design. I have encountered such cases (but I don't think the Radeon driver contained any of them - however the MGA driver did.) I fixed all of them. Fortunately there were not too many. There are better ways to obtain the information that is needed than to rely on the handle to contain a certain piece of information. Anyway, the point is that the handles can't be completely arbitrary for all types of mappings, at least not without checking a lot of code... Well, for some mappings we may be able to pass on the old values (if they fit into 32 bit) This is what my latest code does. It still produces ambiguities which need to be resolved. I'm going to attach a patch to my latest version of the code that addresses some security problems. The code can be compied to use either the old or new ioctl32 sceme. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?

Please do not reply to this email: if you want to comment on the bug, go to the URL shown below and enter yourcomments there. https://bugs.freedesktop.org/show_bug.cgi?id=943 --- Additional Comments From [EMAIL PROTECTED] 2005-04-13 07:06 --- One could do a conversion - on the other hand a brakage of the ABI compatibility between client and Xserver would not be all that bad - given that we cannot really distinguish if a 32bit client library contains code that fixes the size or not. The main issue that I ran into was the size of drm_handle_t which I changed from 'long' to 'int'. It's defined in the drm headers however the drm modules don't seem to use it at all. It ensures that the same handles are used in 32 and 64bit and can be exchanged between 32 and 64bit pieces. This is done between the Xserver and 32bit clients. This however requires that 32 and 64bit both return 32bit handles. This may be the reason why my code is more intrusive. Apart from this of all the drivers I fixed I only saw an issue with Matrox. On the DRM portion can you look at the work Paul has done, it is much cleaner and less intrusive, you are also using the old method which is deprecated now in the kernel, the new method is available in Pauls patch in the -mm kernel, maybe Paul can generate a patch against 2.6.11 The kernel ABI really hasn't changed. The ioctls have remained the same. The only change I've made was to make sure the handles passed between kernel and user space fit into 32bit. That means that they are not necessarily real offset values any more. If anything needs real offset values it needs to obtain it thru another way. If fit in 32bits my code attempts to reuse them. If they are 64bit however a 32bit hash is created. It is also make sure that the handles are unique. For your argument about intrusiveness please see above. I'm presently reworking my driver to support both the old and the new method. My intention was to make the creation of 32bit ioctls as boiler plate as possible. My hope was that this would encourage people to provide compat support for every driver. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

I have tested the r300 part of this patch on my G5. I have made the same changes to radeon and r200 and compile-tested them, but I don't have a 64-bit machine with a r100 or r200 graphics card. I agree that the drm_handle_t is the main problem. As for changing the interface, I think we should do that when the next reasonable opportunity arises. But for now, something like this would let us fix the 32/64 problem without breaking anything that currently works. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

Please do not reply to this email: if you want to comment on the bug, go to the URL shown below and enter yourcomments there. https://bugs.freedesktop.org/show_bug.cgi?id=943 --- Additional Comments From [EMAIL PROTECTED] 2005-04-11 11:55 --- I still don't see any reason why the ABI needs to be changed. The comment data structures shared between kernel, Xserver and clients have different sizes is too vague to be useful - which data structures, and what stops them being converted? Let me give you two examples: 1. mga_dri.h MGADRIRec is a data structure that is private to the Matrox DRI driver. It gets initialized in the DRI X driver. A DRI client (better to say the dri client module) can obtain this data structure from the Xserver thru the DRI extension request X_XF86DRIGetDeviceInfo. Usually X Request structures are carefully designed to be machine independent. Not in this case however: Since DRI assumes that communication happens locally it simply copies over the entire structure. If you look at the above structure it contains drmRegion elements. drmRegion contains a pointer and this is 32bit on a 32bit system or for a 32bit client on a 64bit system and 64bit if the binary is 64 bit. Therefore the last element of the MGADRIRec sarea_priv_offset comes at a different offset depending if your client is 32 or 64 bit. If you connect to a 64bit Xserver from a 32bit client your sarea_priv_offset value read by the client is probably wrong. Why should do the conversion? There is no way for the client to know if the structure has been sent by a 32bit or 64bit server. Also the server doesn't know what client is connected. (Only endianess information is transmitted in the X connection block). 2. The SAREA also contains a driver private structure (in case of the matrox driver contained in mga_sarea.h:MGASAREAPrivRec (drm: mga_drm.h:drm_mga_sarea_t). Its data is shared between the kernel and a DRI client. On 64bit systems it's conceivable that the kernel runs 64bit. How can the kernel and a DRI client share data thru a structure with different size? Converting the data structures of the ioctls is the easy part. You can simply write 'wrappers'. The only exception is where the kernel hands over 64bit 'handles' to user space which are used as offsets in mmap(). This doesn't work in 32bit user space. I've solved this problem without changing the ABI. However the handle is no real pointer any more which could cause issues to some drivers. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

I'd like to merge the DRM into the kernel and see who complains and maybe provide a command line option to fall back to the old 32-bit handle for 32-bit systems in case somebody breaks badly... I think between the two of you a clean solution should be possible, breaking the ABI between X and DRI clients isn't as bad as breaking the kernel/userspace boundard but I'd like to keep the 32-bit ABI the same if possible but I guess it might not be, I've no issues with telling someone to upgrade X and DRI at the same time from snapshots.. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

I ran across this with RADEONDRIRec. I checked all the SAREA definitions and they all seem to be OK, fortunately. It may be possible to convert in the client (based on the size of the structure received from the server) so that a new client can run with either a 32-bit or 64-bit server. Longer term I agree that changing the RADEONDRIRec and other structures to be wordsize-independent is a good idea. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

I have used this successfully on a G5 powermac running a ppc64 Linux kernel, using unmodified 32-bit X server and client binaries. Unfortunately without a change in the ABI it is not possible to run 32bit DRI clients on 64 bit servers (or vice versa). The problem is that data structures shared between kernel, Xserver and clients have different sizes. However it is conceivable that users may want to run 32 and 64 applications on the same Xserver. With the reight defines the ioctl converters are very boiler plate. I'm going to attach an updated version of my patch. Presently I have support to the MGA, Radeon and Rage128 driver. The changes to DRM should be backward compatible so that unpatched Xservers and DRI libraries continue to work.

I tested it on an Pure ia32 setup and on my x86-64 setup. I tested with glxgears :) and neverball. It works for me in an pure ia32-setup, in an pure x86-64 setup. It also works when i boot an x86-64 kernel and chroot into my ia32-setup (as i think this is similiar to Pauls setup this was to be expspected). However when i boot into x86-64 and start and x86-64 Xserver and then chroot into my ia32-setup every gl-related operation (glxinfo, neverball ...) segfault. It would be nice, if i could start an x86-64 Xserver and use 32-bit gl-apps (as it is possible with fglrx), however currently i am very happy with the solution to stop my x86-64 Xserver, chroot into my ia32-setup and start the ia32 Xserver (as this was mostly missing using dri on x86-64). If you need more Information (eg on the segfault, or an patch against r300.sf.net drm sources or ...) feel free to ask. Thanks for your work. cheers Jan Kreuzer -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

The patch is against a 2.6.11 Linux kernel tree. I have done the core DRM and the Radeon driver but not any of the other chipset drivers. I haven't changed the ABI, either for 32-bit or for 64-bit processes. I have used this successfully on a G5 powermac running a ppc64 Linux kernel, using unmodified 32-bit X server and client binaries. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

I guess I need to port it again.
