* [POWERPC] Add "is_power_of_2" checking to log2.h.Robert P. J. Day2007-02-071-0/+11
| | | | | | | | | Add the inline function "is_power_of_2()" to log2.h, where the value zero is *not* considered to be a power of two. Signed-off-by: Robert P. J. Day <rpjday@mindspring.com> Acked-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] MPIC: support more than 256 sourcesOlof Johansson2007-02-071-15/+9
| | | | | | | | | | | | | Allow more than the default 256 MPIC sources. Allocates a new flag (MPIC_LARGE_VECTORS) to be used by platform code when instantiating the mpic. I picked 11 bits worth right now since it would cover the number of sources on any hardware I have seen. It can always be increased later if needed.

* [POWERPC] Add PMC type to cputableOlof Johansson2007-02-071-0/+7
| | | | | | | | | | | | | | | Add cputable entries for which type of PMC implementation the processor has. I've only filled in the current 64-bit processors, the unfilled default value will have same behaviour as before so it can be done over time as needed. Also tidy up the dummy_perf implementation a bit, aggregating it into one function with ifdefs instead of several.

| | | | | | | | | | | | It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense.

* [POWERPC] Move ELF_ET_DYN_BASE up to 512MB pointAnton Blanchard2007-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I often test new versions of glibc by doing: LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary> One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded at 0x8000000 (128MB) with the heap right after it. Since we normally link binaries at 0x10000000 (256MB) we only had about 128MB of space for the heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so 0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so 0802f000-08050000 rwxp 0802f000 00:00 0 [heap] 0fe91000-0ffd9000 r-xp 00000000 00:01 33082 /lib/libc-2.5.so 0ffd9000-0ffe8000 ---p 00148000 00:01 33082 /lib/libc-2.5.so 0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so 0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack] One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000. This allows 128MB for the binary (hopefully enough for even the most crazy c++ apps), and with our current layout we will grow the heap up and the stack down, allowing potentially gigabytes of heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 0fe8a000-0ffd3000 r-xp 00000000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffd3000-0ffe3000 ---p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffe3000-0ffea000 r--p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffea000-0ffee000 rwxp 00150000 00:01 3350 /lib/tls/libc-2.3.6.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep 20000000-20018000 r-xp 00000000 00:01 3478 /lib/ld-2.3.6.so 20028000-20029000 r--p 00018000 00:01 3478 /lib/ld-2.3.6.so 20029000-2002a000 rwxp 00019000 00:01 3478 /lib/ld-2.3.6.so 2002a000-2004b000 rwxp 2002a000 00:00 0 [heap] ffd67000-ffd7c000 rw-p ffd67000 00:00 0 [stack] Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] x86: fix PDA variables to work during bootJames Bottomley2007-01-221-0/+1
| | | | | | | | | | | | | | | | | | | The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.

The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account.

This made non-data commands to have random qc->dma_dir. This usually doesn't cause problem because LLDs usually check qc->protocol first and look at qc->dma_dir iff the command needs data transfer but this doesn't hold for all LLDs. It might be worthwhile to rename qc->dma_dir to qc->data_dir as we use the field to tag data direction for both PIO and DMA protocols. This problem has been spotted by James Bottomley.

The comparison to determine if the decrement will make the result negative was done by the "addic." instruction, which operates on a 64-bit value, namely the zero-extended word loaded from the atomic variable. This patch uses an explicit word compare (cmpwi) and changes the addic. to an addi (also changing "=&r" to "=&b" so that r0 isn't used, and addi doesn't become li). This also fixes a bug for both 32-bit and 64-bit in that previously 0x80000000 was considered positive, since the result after decrementing is positive. Now it is considered negative. Also, I clarify the return value in the comments just to make it clear that the value returned is always the decremented value, even if that value is not stored back to the atomic counter.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a problem, pointed by Meelis Roos <mroos@linux.ee>, that, on ppc32 arch, with some gcc versions (noticed with prerelease 4.1.2 20061115), compilation fails, due the lack of __ucmpdi2 to do the required 64-bit comparision.
