Services like ACPI namespace are not available and there are non-trivial problems to moving them to early boot. However, there's no reason we can't change to a different machvec later in boot when the services we need are available. By adding a entry point for later initialization of the swiotlb, we can add an error path for the hpzx1 machevec initialization and fall back to the DIG machine vector if IOMMU hardware isn't found in the system. Since ia64 uses 4GB for zone DMA (no ISA support), it's trivial to allocate a contiguous range from the slab for bounce buffer usage.

Without PNP, it probes legacy I/O ports for the keyboard controller, which causes an MCA on HP boxes. Also, I'm about to remove 8250_acpi.c, so we'll need PNP to detect non-PCI serial ports. Until 8250_acpi.c is removed, some systems will see serial ports reported twice (once from 8250_acpi.c and again from 8250_pnp.c). This is harmless. PNPACPI is still marked EXPERIMENTAL, but I'm not aware of any outstanding issues on ia64. IDE_GENERIC turned off (except for SGI simulator, all ia64 IDE is PCI) ide-generic probes compiled-in legacy I/O ports for IDE devices, which again causes an MCA. It would be nicer to just get rid of all the legacy junk from include/asm-ia64/ide.h, but that is a bit riskier because it could break ide-cs and the HDIO_REGISTER_HWIF ioctl (http://www.ussg.iu.edu/hypermail/linux/kernel/0508.2/0049.html).

This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: Jack Steiner Signed-off-by: Tony Luck --- arch/ia64/sn/kernel/io_init.c | 4 +- arch/ia64/sn/kernel/setup.c | 160 ++++++++++++------------------------ arch/ia64/sn/kernel/sn2/sn_hwperf.c | 4 +- arch/ia64/sn/kernel/tiocx.c | 5 +- arch/ia64/sn/kernel/xpc_partition.c | 2 +- drivers/char/snsc.c | 4 +- include/asm-ia64/sn/arch.h | 36 +++++--- include/asm-ia64/sn/io.h | 2 +- include/asm-ia64/sn/klconfig.h | 34 +------- include/asm-ia64/sn/sn_cpuid.h | 3 - include/asm-ia64/sn/sn_sal.h | 12 +-- include/asm-ia64/sn/xp.h | 2 +- 12 files changed, 92 insertions(+), 176 deletions(-) (limited to 'arch/ia64') diff --git a/arch/ia64/sn/kernel/io_init.c b/arch/ia64/sn/kernel/io_init.c index 906622d9f93..b4f5053f5e1 100644 --- a/arch/ia64/sn/kernel/io_init.c +++ b/arch/ia64/sn/kernel/io_init.c @@ -22,8 +22,6 @@ #include "xtalk/hubdev.h" #include "xtalk/xwidgetdev.h" -nasid_t master_nasid = INVALID_NASID; /* Partition Master */ - static struct list_head sn_sysdata_list; /* sysdata list struct */ @@ -165,7 +163,7 @@ static void sn_fixup_ionodes(void) * Get SGI Specific HUB chipset information. * Inform Prom that this kernel can support domain bus numbering. */ - for (i = 0; i < numionodes; i++) { + for (i = 0; i < num_cnodes; i++) { hubdev = (struct hubdev_info *)(NODEPDA(i)->pdinfo); nasid = cnodeid_to_nasid(i); hubdev->max_segment_number = 0xffffffff; diff --git a/arch/ia64/sn/kernel/setup.c b/arch/ia64/sn/kernel/setup.c index 6f8c5883716..0fb579ef18c 100644 --- a/arch/ia64/sn/kernel/setup.c +++ b/arch/ia64/sn/kernel/setup.c @@ -59,8 +59,6 @@ DEFINE_PER_CPU(struct pda_s, pda_percpu); #define MAX_PHYS_MEMORY (1UL << IA64_MAX_PHYS_BITS) /* Max physical address supported */ -lboard_t *root_lboard[MAX_COMPACT_NODES]; - extern void bte_init_node(nodepda_t *, cnodeid_t); extern void sn_timer_init(void); @@ -97,15 +95,15 @@ u8 sn_region_size; EXPORT_SYMBOL(sn_region_size); int sn_prom_type; /* 0=hardware, 1=medusa/realprom, 2=medusa/fakeprom */ -short physical_node_map[MAX_PHYSNODE_ID]; +short physical_node_map[MAX_NUMALINK_NODES]; static unsigned long sn_prom_features[MAX_PROM_FEATURE_SETS]; EXPORT_SYMBOL(physical_node_map); -int numionodes; +int num_cnodes; static void sn_init_pdas(char **); -static void scan_for_ionodes(void); +static void build_cnode_tables(void); static nodepda_t *nodepdaindr[MAX_COMPACT_NODES]; @@ -139,19 +137,6 @@ extern char drive_info[4 * 16]; char drive_info[4 * 16]; #endif -/* - * Get nasid of current cpu early in boot before nodepda is initialized - */ -static int -boot_get_nasid(void) -{ - int nasid; - - if (ia64_sn_get_sapic_info(get_sapicid(), &nasid, NULL, NULL)) - BUG(); - return nasid; -} - /* * This routine can only be used during init, since * smp_boot_data is an init data structure. @@ -223,7 +208,6 @@ void __init early_sn_setup(void) } extern int platform_intr_list[]; -extern nasid_t master_nasid; static int __initdata shub_1_1_found = 0; /* @@ -269,7 +253,6 @@ static void __init sn_check_for_wars(void) void __init sn_setup(char **cmdline_p) { long status, ticks_per_sec, drift; - int pxm; u32 version = sn_sal_rev(); extern void sn_cpu_init(void); @@ -300,11 +283,10 @@ void __init sn_setup(char **cmdline_p) MAX_DMA_ADDRESS = PAGE_OFFSET + MAX_PHYS_MEMORY; - memset(physical_node_map, -1, sizeof(physical_node_map)); - for (pxm = 0; pxm < MAX_PXM_DOMAINS; pxm++) - if (pxm_to_nid_map[pxm] != -1) - physical_node_map[pxm_to_nasid(pxm)] = - pxm_to_nid_map[pxm]; + /* + * Build the tables for managing cnodes. + */ + build_cnode_tables(); /* * Old PROMs do not provide an ACPI FADT.

bigger disks The simscsi code at present overflows an int if it's given a large disk image. The attached patch increases the possible size to 128G. While it's unlikely that anyone will want to use SKI with such a large drive, the same framework is currently being used for various virtualisation experiments.

When a process enters flush_tlb_range() to purge TLBs for another process, it is possible to avoid flush_tlb_all() and instead allow sn2_global_tlb_purge() to purge TLBs only where necessary. This patch modifies flush_tlb_range() so that this case can be handled by platform TLB purge functions and updates ia64_global_tlb_purge() accordingly. sn2_global_tlb_purge() now calculates the region register value from the mm argument introduced with this patch.

The test can be unnecessarily long (and occurs while holding the tasklist_lock). Especially long on a large system with thousands of active tasks. The ptrace caller (presumably a debugger) specifies the pid of its target and an address to peek or poke. But the debugger could be attached to several tasks. The idea of find_thread_for_addr() is to find whether the target address is in the RBS for any of those tasks. Currently it searches the thread-list of the target pid. If that search does not find a match, and the shared mm-struct's user count indicates that there are other tasks sharing this address space (a rare occurrence), a search is made of all the tasks in the system. Another approach can drastically shorten this procedure. It depends upon the fact that in order to peek or poke from/to any task, the debugger must first attach to that task. And when it does, the attached task is made a child of the debugger (is chained to its children list). Therefore we can search just the debugger's children list.
