drm: Lower priority of "EDID checksum is invalid" message The priority goes from "error" to "debug". Connectors are polled every 10 seconds. Reading EDID is part of this polling. However, when an invalid EDID is returned, this error message is logged. When using Newcons for instance, having a kernel message every 10 seconds is getting annoying. Now that it's a debug message, it'll be logged only if hw.dri.debug is enabled. This fix console spamming for some users. Tested by: Larry Rosenman Approved by: re (gjb)

drm/ttm, drm/radeon: Replace EINTR/ERESTART by ERESTARTSYS... ... for msleep/cv_*wait() return values, where wait_event*() is used on Linux. ERESTARTSYS is the return code expected by callers when the operation was interrupted. For instance, this is the case of radeon_cs_ioctl() (radeon_cs.c): if an error occurs, and the code isn't ERESTARTSYS (eg. EINTR), it logs an error. Note that ERESTARTSYS is defined as ERESTART, but this keeps callers' code close to Linux. Submitted by: avg@ (previous version) Approved by: re (gjb)

vga_pci: Improve boot display detection The previous code was checking the "VGA Enable" bit on the video card's parent PCI-to-PCI bridge only. This didn't work for the case where the video card is attached to the root PCI bus (ie. the card has no parent PCI-to-PCI bridge). Now, the new code: 1. checks the "VGA Enable" bit on the parent bridge only if it's a PCI-to-PCI bridge; 2. always checks the "I/O" and "Memory address space decoding" bits on the video card itself. However, vendor-specific bits are not used. This fixes the use of many integrated Radeon cards: without this patch, we fail to detect them as the boot display and, when radeonkms looks for the Video BIOS, it skips the shadow copy made by the System BIOS. It then fails to fully initialize the card, because the shadow copy is the only way to read the Video BIOS in these situations. A workaround was to force the boot display selection using the "hw.pci.default_vgapci_unit" tunable. A previous version of this patch added a new function doing the checks. Now, the vga_pci_is_boot_display() function is used to perform the checks (only until the boot display is found) and return if the given device is the boot display or not. Furthermore, vga_pci_attach() logs "Boot video device" if the card being attached it the Chosen One: vgapci0: [...] vgapci0: Boot video device Reviewed by: kib@, jhb@ (both a previous version) Tested by: lunatic_ (#freebsd-xorg, integrated Radeon card, xmj (#freebsd-xorg, i915+NVIDIA cards) Approved by: re (gjb)

drm/radeon: radeon_dp_i2c_aux_ch() must return 0 on FreeBSD The code was unmodified compared to Linux and returned the amount of received bytes from the i2c bus. This led to non-working i2c bus and failure to eg. read monitor's EDID, if connected to DisplayPort. Tested by: Mikaël Urankar Approved by: re (gjb)

drm/radeon: agp_info->ai_aperture_size is in bytes, not Mbytes This fixes radeon_agp_init() and gtt_size is now correct. However, this is not enough to make Radeon AGP cards work: ttm_agp_backend.c isn't implemented yet. Submitted by: tijl@ Approved by: re (gjb)
