2005-09-03	convert ioctl flags to use flags instead of separate ints	Dave Airlie

2005-08-26	- Don't try to allocate mappings of less than a PAGE_SIZE in MGA DMA code.	Eric Anholt
	- Comment out the "is this mapping/bufs in allocated AGP" bits in BSD because they break mga (which uses AGP allocation that doesn't track entries). It's not a security issue when we still have the related ioctls marked root-only. - Apply some power-of-two alignment restrictions to hopefully avoid some panicing in bad cases of drm_pci_alloc() on FreeBSD. - Add verbosity to some error handling that I found useful while debugging.

Otherwise malicious clients can register allocations on other clients or free memory used by other clients which will lead to severe memory manager inconsistensies. 2005-08-09Make sure savage has 3rd ioctl parameterJon Smirl 2005-08-07make some functions static in the savage drm driverDave Airlie 2005-08-07fix ioctl in r128 drm direction from Egbert Eich.Dave Airlie 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) 2005-08-04Mark some radeon init variables deprecated. These used to be passed in butJon Smirl the driver already knew their correct value. For example the physical address of the framebuffer and registers. 2005-08-04Split the control of master vs root priv. Everything is still marked asJon Smirl needing root. 2005-08-04Whitespace fixups.Eric Anholt 2005-08-04Fix the MGA driver on BSD by passing in the proper chipset flags to theEric Anholt driver's preinit routine, and by using DRM_COPY_TO_USER_IOCTL when copying out to an ioctl's data pointer.

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.

Same support is available fromJon Smirl radeonfb. 2005-06-17fix up drm_alloc_agp to take a dev arg and not pass crappy agpgart aroundDave Airlie 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 2005-06-11fix up drm.h for C++ include as this can be included in user programsDave Airlie 2005-06-10add dragonfly #define from Xorg CVSDave Airlie 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.
