Dennis Kempin 70c66baed0 Revert "Devices: Allocate non pci bar mmio at top of HighMmio" ... This reverts commit 9557588786. Reason for revert: Causes crosvm to not start on AMD based devices b/204222491 Original change's description: > Devices: Allocate non pci bar mmio at top of HighMmio > > Some devices like virtio-pmem, intel host bridge need private mmio, these private > mmio isn't exposed to Vm through pci bar, and crosvm use mmio allocation interface > to allocate them, so guest OS pci bus driver couldn't detect them, and once guest > OS reallocate pci mmio, these private mmmio could be assigned to pci device bar. > then resource conflict happens. > > This patch allocates these non pci bar mmio at the top of HighMmio, since HighMmio > is large enough and OS allocates pci mmio from low to high. So these non pci bar > mmio won't conflict with pci bar. > > BUG=b:199442120 > BUG=b:185084350 > TEST=crosvm run --pmem-device xxxx > > Change-Id: I615d7901d595dd46ba6362f88b71d96baa9c4c8f > Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3184549 > Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> > Tested-by: kokoro <noreply+kokoro@google.com> > Commit-Queue: Daniel Verkamp <dverkamp@chromium.org> Bug: b:199442120 Bug: b:185084350 Change-Id: Ida1369bf0b70782633b1073ceef50e1bab108f55 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3248906 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Commit-Queue: Dennis Kempin <denniskempin@google.com>		2021-10-27 23:22:53 +00:00
