2005-08-16add Egberts 32/64 bit patch (its in kernel already...)Dave Airlie
2005-08-15Port the VIA DRM to FreeBSD. Original patch by Jake, with some cleanup byEric Anholt
me to match other drivers and avoid ifdeffing. The linux via_drv.c will be moved from shared-core to linux-core soon by repocopy. Submitted by: Jake Burkholder <jake@FreeBSD.org> Tested by: unichrome
2005-08-12Reverting the previous via security-fix commit, since the assumption ofThomas Hellstrom
contexts registered with the callers filp was wrong.

2005-08-10Security fix on via: Checking that the specified context belongs to theThomas Hellstrom
caller on fb / agp memory alloc and free. Otherwise malicious clients can register allocations on other clients or free memory used by other clients which will lead to severe memory manager inconsistensies.

2005-08-05Rename the driver hooks in the DRM to something a little moreEric Anholt
understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)

2005-06-29Bug in conversion from old DRM to core DRM....Dave Airlie
2005-06-28- Remove drm_initmap and replace its usage with drm_addmap. This reducesEric Anholt
code duplication, and it also hands you the map pointer so you don't need to re-find it. - Remove the permanent maps flag. Instead, for register and framebuffer maps, we always check whether there's already a map of that type and offset around. Move the Radeon map initialization into presetup (first open) so it happens again after every takedown. - Remove the split cleanup of maps between driver takedown (last close) and cleanup (module unload). Instead, always tear down maps on takedown, and drivers can recreate them on first open. - Make MGA always use addmap, instead of allocating consistent memory in the PCI case and then faking up a map for it, which accomplished nearly the same thing, in a different order. Note that the maps are exposed to the user again: we may want to expose a flag to avoid this, but it's not a security concern, and saves us a lot of code. - Remove rmmaps in the MGA driver. Since the function is only called during takedown anyway, we can let them die a natural death. - Make removal of maps happen in one function, which is called by both drm_takedown and drm_rmmap_ioctl.

2005-06-14Adds support for PCI cards to MGA DRMIan Romanick
This patch adds serveral new ioctls and a new query to get_param query to support PCI MGA cards. Two ioctls were added to implement interrupt based waiting. With this change, the client-side driver no longer needs to map the primary DMA region or the MMIO region. Previously, end-of-frame waiting was done by busy waiting in the client-side driver until one of the MMIO registers (the current DMA pointer) matched a pointer to the end of primary DMA space. By using interrupts, the busy waiting and the extra mappings are removed. A third ioctl was added to bootstrap DMA. This ioctl, which is used by the X-server, moves a *LOT* of code from the X-server into the kernel. This allows the kernel to do whatever needs to be done to setup DMA buffers. The entire process and the locations of the buffers are hidden from user-mode. Additionally, a get_param query was added to differentiate between G4x0 cards and G550 cards. A gap was left in the numbering sequence so that, if needed, G450 cards could be distinguished from G400 cards. According to Ville Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering differently. This seems the most compatible way to let the client-side driver know which card it's own. Doing this very small change now eliminates the need to bump the DRM minor version twice. http://marc.theaimsgroup.com/?l=dri-devel&m=106625815319773&w=2 A number of ioctl handlers in linux-core were also modified so that they could be called in-kernel. In these cases, the in-kernel callable version kept the existing name (e.g., drm_agp_acquire) and the ioctl handler added _ioctl to the name (e.g., drm_agp_acquire_ioctl). This patch also replaces the drm_agp_do_release function with drm_agp_release. drm_agp_release (drm_core_agp_release in the previous patch) is very similar to drm_agp_do_release, and I saw no reason to have both. This commit *breaks the build* on BSD. Eric said that he would make the required updates to the BSD side soon. Xorg bug: 3259 Reviewed by: Eric Anholt
2005-06-09Completely re-initialize DMA settingsIan Romanick
There were two problems. First, the 'warp' and 'primary' pointers weren't cleared, so mga_do_cleanup_dma, which gets called multiple times, would try to ioremapfree them multiple times. This resulted in the new error messages to syslog. The second problem was the, since the dev_private structure isn't reallocated and cleaned out in mga_do_init_dma, when the server is reloaded idle-waits would wait for impossible values. I have given this patch some more riggorous testing. This includes: - Load module, start server, run GL app, stop server, unload module. - Load module, start server, run GL app, stop server, unload module, reload module, restart server, run GL app. - Load module, start server, run GL app, stop server, restart server, run GL app, stop server, unload module. In all three cases, everything worked as expected. Please let me know if there are any further regressions with this patch. Xorg bug: 3408 Reported by: Chris Rankin
