Miller" Date: Tue, 15 May 2007 17:03:54 -0700 Subject: [SPARC64]: Add hypervisor API negotiation and fix console bugs. Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.

Currently it's worked around by caching n_sectors before turning off HPA. The cached original size is overwritten if the device is reconfigured without being hardreset - which always happens after configuring trasnfer mode. If the device gets hardreset for some reason after that, revalidation fails with -ENODEV. This patch makes size checking more robust by moving n_sectors check from ata_dev_reread_id() to ata_dev_revalidate() after the device is fully configured. No matter what happens during configuration, a device must have the same n_sectors after fully configured to be treated as the same device.
