From 41019fecc83c466faeddbc6b3784a447516c03a7 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 19 Apr 2011 11:54:50 +1000 Subject: [PATCH 01/17] pseries: Increase maximum CPUs to 256 The original pSeries machine was limited to 32 CPUs, more or less arbitrarily. Particularly when we get SMT KVM guests it will be pretty easy to exceed this. Therefore, raise the max number of CPUs in a pseries machine guest to 256.

Unfortunately this confuses some installers and ybin, which expect this to start with "IBM" on pSeries machines. This patch addresses this problem, making the property more closely resemble the pattern of existing real hardware.

However, existing pSeries machines running pHyp number them from 0x30000000. In theory these indices are arbitrary, since everything necessary for the kernel to find them is advertised in the device tree. However the debian installer, at least, incorrectly looks for a device named vty@30... to determine whether to use the hypervisor console. Therefore this patch moves the numbers we use to match the existing pHyp practice, in order to workaround broken userspace apps of this type.

Check the capability before calling KVM_SET_SREGS. Without this, booke kvm fails to boot as of commit 84b4915dd2c0eaa86c970ffc42a68ea8ba9e48b5 (kvm: Handle kvm_init_vcpu errors). Also, don't write random stack state into the non-PVR sregs fields -- have kvm fill it in first. Eventually booke will have sregs and it will have its own capability to be tested here. However, we will want a way for platform code to request to look like the actual CPU we're running on, especially if SoC devices are being directly assigned.

Unfortunately, the hardware alignments don't match here: There are RAM and MMIO regions within a single page when it's 64kb in size. So the only way out for now is to tell the user that he should use 4k PAGE_SIZE. This patch gives the user a hint on that, telling him that failing to register a prefix slot is most likely to be caused by mismatching PAGE_SIZE. This way it's also more future-proof, as bigger PAGE_SIZE can easily be supported by other machines then, as long as they stick to 64kb granularities.

This feature mask is 64 bits long and we just successfully exceeded those 64 bits. To add more features, we need to think of something. The easiest solution that came to my mind was to simply add another 64 bits that we can also match on. Since the comparison is only done on start of the qemu process to generate an internal opcode calling table, we should be fine on any performance penalties here.

Date: Sat, 30 Apr 2011 23:34:58 +0200 Subject: [PATCH 15/17] PPC: Implement e500 (FSL) MMU Most of the code to support e500 style MMUs is already in place, but we're missing on some of the special TLB0-TLB1 handling code and slightly different TLB modification. This patch adds support for the FSL style MMU.
