| | | | | | | capability is present as not all devices supported by the agp_i810 driver (such as i915) have the AGP capability. Instead, add an identify routine to the agp_i810 driver that uses the PCI ID to determine if it should create an agp child device.

| | | | | - Axe macros used for walking PCI capabilities list. We now ask the PCI bus to find caps for us rather than doing it in the drm and agp drivers.

| | | | | | | | | the addition of pci_find_extcap(). - Change the drm drivers to attach to vgapci. This is #ifdef'd so the code can be shared across branches. - Use pci_find_extcap() to look for AGP and PCIE capabilities in drm. - GC all the drmsub stuff for i810/i830/i915. The agp and drm devices are now both children of vgapci.

| | | | | | | | | attach to the hostb driver instead. This means that agp can now be loaded at runtime (in theory at least). Also, the drivers no longer have to explicity call device_verbose() to cancel out any earlier calls to device_quiet() by the hostb(4) driver (this shows a limitation in new-bus, drivers really shouldn't be doing device_quiet() until they know they are going to drive that device, i.e. in attach).

| | | | | | | | | | | and some fixes from Motomichi Matsuzaki. Testing involved many people, but the final, successful testing was from rwatson who endured several rounds of "it crashes at XYZ stage" "oh, please correct this typo and try again." The Linux driver, and to a small extent the limited specs, were both used as a reference for how to program the chipset. PR: kern/80396 Submitted by: Martin Mersberger

| | | | | | | | | | | | | | | | | control register and AGP bridge seems to be inconsistent with some BIOS. Instead of relying on BIOS settings, we just take the initial aperture size and encode them for both miscellaneous control register and AGP bridge. Some idea was borrowed from agp_nvidia.c. - Add preliminary ULi M1689 chipset support. The idea was taken from Linux because hardware and documentation are unavailable. Not tested. - Add more VIA chipset PCI IDs taken from Linux driver.

* [1] Remove the generic bridge support from those drivers that had it. Theanholt2004-12-304-15/+55
| | | | | | | | | | | generic bridge support was biting us more than it helped, whenever a new chipset came out from a vendor and misprogramming it caused strange hangs or corruption. [2] Add a large number of PCI IDs based on what the linux drivers support. Note that the new PCI IDs haven't been tested, they're just *likely* to work. In particular the VIA AGP 8x chipsets are concerning, due to lack of testing, possible issues (kern/69953), and not having a nice "does this bridge say it would do 8x" function. However, this shouldn't make the situation worse, since these chips would have probed in the past anyway.

If v2 was chosen, the chipset needs to be programmed with the v2 registers still. Also included in kern/69953 are changes to make the programming of the v3 registers match linux, but that will be left out until the need to do so is confirmed (want specs or a tester).

Currently the 8385 host bridge used on amd64 is the only bridge to use the AGP3_VIA_* register offsets and all other bridges use the AGP_VIA_* offsets. It is currently unclear if the AGP3_VIA_* offsets are for VIA bridges that implement AGP 3.0 bridges or just for amd64 bridges. Submitted by: Kenneth Culver culverk at sweetdreamsracing dot biz
* Push down the responsibility for zeroing a physical page from thealc2004-04-242-4/+0
| | | | | | | | | | | | | caller to vm_page_grab(). Although this gives VM_ALLOC_ZERO a different meaning for vm_page_grab() than for vm_page_alloc(), I feel such change is necessary to accomplish other goals. Specifically, I want to make the PG_ZERO flag immutable between the time it is allocated by vm_page_alloc() and freed by vm_page_free() or vm_page_free_zero() to avoid locking overheads. Once we gave up on the ability to automatically recognize a zeroed page upon entry to vm_page_free(), the ability to mutate the PG_ZERO flag became useless. Instead, I would like to say that "Once a page becomes valid, its PG_ZERO flag must be ignored."
