| * [POWERPC] vmemmap fixes to use smaller pagesBenjamin Herrenschmidt2008-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes vmemmap to use a different region (region 0xf) of the address space, and to configure the page size of that region dynamically at boot. The problem with the current approach of always using 16M pages is that it's not well suited to machines that have small amounts of memory such as small partitions on pseries, or PS3's. In fact, on the PS3, failure to allocate the 16M page backing vmmemmap tends to prevent hotplugging the HV's "additional" memory, thus limiting the available memory even more, from my experience down to something like 80M total, which makes it really not very useable. The logic used by my match to choose the vmemmap page size is: - If 16M pages are available and there's 1G or more RAM at boot, use that size. - Else if 64K pages are available, use that - Else use 4K pages I've tested on a POWER6 (16M pages) and on an iSeries POWER3 (4K pages) and it seems to work fine. Note that I intend to change the way we organize the kernel regions & SLBs so the actual region will change from 0xf back to something else at one point, as I simplify the SLB miss handler, but that will be for a later patch.

| * [POWERPC] 86xx: mpc8610_hpcd: use ULI526X driver for on-board ethernetAnton Vorontsov2008-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of current mainline tree, TULIP driver is unusable on MPC8610HPCD boards. There is a patch[1] floating around (and also included in the BSP), which tries to heal the situation, though the ethernet is still unusable. Practically it takes ages to mount NFS filesystem: VFS: Mounted root (nfs filesystem). Freeing unused kernel memory: 180k init nfs: server 10.0.0.2 not responding, still trying nfs: server 10.0.0.2 OK nfs: server 10.0.0.2 not responding, still trying nfs: server 10.0.0.2 not responding, still trying nfs: server 10.0.0.2 not responding, still trying nfs: server 10.0.0.2 not responding, still trying nfs: server 10.0.0.2 OK nfs: server 10.0.0.2 not responding, still trying So, instead of trying to add uli526x functionality into TULIP driver (which is already bloated enough), I fixed existing ULI526X driver and now it works perfectly well here.

| * | [IA64] fix personality(PER_LINUX32) performance issueHuang, Xiaolan2008-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch aims to fix a performance issue for the syscall personality(PER_LINUX32). On IA-64 box, the syscall personality (PER_LINUX32) has poor performance because it failed to find the Linux/x86 execution domain. Then it tried to load the kernel module however it failed always and it used the default execution domain PER_LINUX instead. Requesting kernel modules is very expensive. It caused the performance issue. (see the function lookup_exec_domain in kernel/exec_domain.c). To resolve the issue, execution domain Linux/x86 is always registered in initialization time for IA-64 architecture.

However, in most cases, the kernel needs some memory below that limit that is DMA-capable. So in this machine configuration, the crashkernel will be reserved above 4 GB. For machines that use SWIOTLB implementation because they lack an I/O MMU the low memory is required by the SWIOTLB implementation. In that case, it doesn't make sense to reserve the crashkernel at all because it's unusable for kdump. A special case is the "hpzx1" machine vector. In theory, it has a I/O MMU, so it can be booted above 4 GB. However, in the kdump case that is not possible because of changeset 51b58e3e26ebfb8cd56825c4b396ed251f51dec9: On HP zx1 machines, the 'machvec=dig' parameter is needed for the kdump kernel to avoid problems with the HP sba iommu. The problem is that during the boot of the kdump kernel, the iommu is re-initialized, so in-flight DMA from improperly shutdown drivers causes an IOTLB miss which leads to an MCA. With kdump, the idea is to get into the kdump kernel with as little code as we can, so shutting down drivers properly is not an option. The workaround is to add 'machvec=dig' to the kdump kernel boot parameters. This makes the kdump kernel avoid using the sba iommu altogether, leaving the IOTLB intact. Any ongoing DMA falls harmlessly outside the kdump kernel. After the kdump kernel reboots, all devices will have been shutdown properly and DMA stopped. This patch pushes that functionality into the sba iommu initialization code, so that users won't have to find the obscure documentation telling them about 'machvec=dig'. This means that also for hpzx1 it's not possible to boot when all memory is above the 4 GB limit. So the only machine vectors that can handle this case are "sn2" and "uv".

Add a common hi/lo helper to avoid the shifting masking that is done to get the upper and lower nibbles of a byte value. Pull the pack_hex_byte helper from kgdb as it is opencoded many places in the tree that will be consolidated.

This is a little rework of the "Don't initialize a pre-allocated framebuffer" patch that corrects the call to ioremap_writecombine() function. It also cuts the use of internal SRAM for at91sam9rl : it is a bit small for a framebuffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The user_regset_view table for the 32-bit regsets on the 64-bit build had the wrong sizes for the FP regsets. This bug had no user-visible effect (just on kernel modules using the user_regset interfaces and the like). But the fix is trivial and risk-free.

Though the low mappings were removed at bootup, they were left behind (with Global flags helping to keep them in TLB) after resume or cpu online, causing the crashes seen. Reinstate zap_low_mappings (with local __flush_tlb_all) for each cpu_up on x86_32. This used to be serialized by smp_commenced_mask: that's now gone, but a low_mappings flag will do. No need for native_smp_cpus_done to repeat the zap: let mem_init zap BSP's low mappings just like on UP. (In passing, fix error code from native_cpu_up: do_boot_cpu returns a variety of diagnostic values, Dprintk what it says but convert to -EIO. And save_pg_dir separately before zap_low_mappings: doesn't matter now, but zapping twice in succession wiped out resume's swsusp_pg_dir.) That worked well on the duo and one quad, but wouldn't boot 3rd or 4th cpu on P4 Xeon, oopsing just after unlock_ipi_call_lock. The TLB flush IPI now being sent reveals a long-standing bug: the booting cpu has its APIC readied in smp_callin at the top of start_secondary, but isn't put into the cpu_online_map until just before that unlock_ipi_call_lock. So native_smp_call_function_mask to online cpus would send_IPI_allbutself, including the cpu just coming up, though it has been excluded from the count to wait for: by the time it handles the IPI, the call data on native_smp_call_function_mask's stack may well have been overwritten. So fall back to send_IPI_mask while cpu_online_map does not match cpu_callout_map: perhaps there's a better APICological fix to be made at the start_secondary end, but I wouldn't know that.
