* [POWERPC] Use ppc_md.hpte_insert() in htab_bolt_mapping()Michael Ellerman2006-06-281-28/+6
| | | | | | | | With the ppc_md htab pointers setup earlier, we can use ppc_md.hpte_insert in htab_bolt_mapping(), rather than deciding which version to call by hand. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] powerpc: Initialise ppc_md htab pointers earlierMichael Ellerman2006-06-2810-76/+58
| | | | | | | | | | Initialise the ppc_md htab callbacks earlier, in the probe routines. This allows us to call htab_finish_init() from htab_initialize(), and makes it private to hash_utils_64.c. Move htab_finish_init() and make_bl() above htab_initialize() to avoid forward declarations. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Export flat device tree via debugfs for debuggingMichael Ellerman2006-06-281-0/+25
| | | | | | | | | | | | | | If DEBUG is turned on in prom.c, export the flat device tree via debugfs. This has been handy on several occasions. To look at it: # mount -t debugfs none /sys/kernel/debug # od -a /sys/kernel/debug/powerpc/flat-device-tree and/or # dtc -fI dtb /sys/kernel/debug/powerpc/flat-device-tree -O dts Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Remove remaining iSeries debugger cruftMichael Ellerman2006-06-282-40/+9
| | | | | | | | | | | None of this seems to be necessary, so let's see if can remove it and not break anything. Booted on iSeries & pSeries here. NB. we don't remove the hvReleaseData, we just move it down so that the file reads more clearly.

* [POWERPC] kdump: Reserve the existing TCE mappings left by the first kernelHaren Myneni2006-06-282-0/+63
| | | | | | | | | | | | | | | | | | | | | | During kdump boot, noticed some machines checkstop on dma protection fault for ongoing DMA left in the first kernel. Instead of initializing TCE entries in iommu_init() for the kdump boot, this patch fixes this issue by walking through the each TCE table and checks whether the entries are in use by the first kernel. If so, reserve those entries by setting the corresponding bit in tbl->it_map such that these entries will not be available for the kdump boot. However it could be possible that all TCE entries might be used up due to the driver bug that does continuous mapping. My observation is around 1700 TCE entries are used on some systems (Ex: P4) at some point of time during kdump boot and saving dump (either write into the disk or sending to remote machine). Hence, this patch will make sure that minimum of 2048 entries will be available such that kdump boot could be successful in some cases.

A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some i386/x86_64 systems, sending an NMI IPI as a broadcast will reset the system. This seems to be a BIOS bug which affects machines where one or more cpus are not under OS control. It occurs on HT systems with a version of the OS that is not compiled without HT support. It also occurs when a system is booted with max_cpus=n where 2 <= n < cpus known to the BIOS. The fix is to always send NMI IPI as a mask instead of as a broadcast.

From SDM Vol-3A "Valid Interrupt Vectors" section: "When an illegal vector value (0-15) is written to an LVT entry and the delivery mode is Fixed, the APIC may signal an illegal vector error, with out regard to whether the mask bit is set or whether an interrupt is actually seen on input."

Also fixes problem in compat_sys_kexec_load() which could allocate more than 128 bytes using compat_alloc_user_space().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86_64 and i386 behave inconsistently when sending an IPI on vector 2 (NMI_VECTOR). Make both behave the same, so IPI 2 is sent as NMI. The crash code was abusing send_IPI_allbutself() by passing a code instead of a vector, it only worked because crash knew about the internal code of send_IPI_allbutself(). Change crash to use NMI_VECTOR instead, and remove the comment about how crash was abusing the function. This patch is a pre-requisite for fixing the problem where sending an IPI as NMI would reboot some Dell Xeon systems. I cannot fix that problem while crash continus to abuse send_IPI_allbutself(). It also removes the inconsistency between i386 and x86_64 for NMI_VECTOR. That will simplify all the RAS code that needs to bring all the cpus to a clean stop, even when one or more cpus are spinning disabled.
