| | | | | | | | | | | | | For sys/boot/i386 and sys/boot/pc98, separate flags to be passed directly to the linker (LD_FLAGS) from flags passed indirectly, via the compiler driver (LDFLAGS). This is because several Makefiles under sys/boot/i386 and sys/boot/pc98 use ${LD} directly to link, and the normal LDFLAGS value should not be used in these cases.

| | | | | | | | | | | | | | When rebooting (exiting) from the BTX loader, make sure to restore the GDT from the correct segment, otherwise a triple fault would be caused. In some virtual environments (VMware, VirtualBox, etc) this could lead to a unhandled error or hang in the guest emulation software. Thanks to avg and jhb for a few hints in the right direction.

| | | | | | | | | | | | | | | | Fix a bug introduced in r223938 (MFC'ed to stable/7 in r224410); on big-endian machines coping a 32-bit quantum bytewise to the address of a 64-bit variable results in writing to the "wrong" 32-bit half so adjust the address accordingly. This fix is implemented in a hackish way for two reasons: o in order to be able to get it into 8.3 with zero impact on the little- endian architectures where this bug has no effect and o to avoid blowing the x86 boot2 out of the water again when compiling it with clang, which all sane versions of this fix tested do. This change fixes booting from UFS1 file systems on big-endian machines. Notes: svn path=/stable/7/; revision=232966

| | | | | | | | | | | | | | Remove reading of symbols from a.out loaded files. Since we are tight on space for clang and a.out support is only needed for /boot/loader, they are excess bytes that serve no useful purpose other than to support really old kernels (FreeBSD < 3.2 or so).

| | | | | | | | | | | | | | Since r219452 the alignment of __dmadat has changed, revealing that fsread() bogusly casts its contents around causing alignment faults on sparc64 and most likely also on at least powerpc. Fix this by copying the contents bytewise instead as partly already done here. Solving this the right way costs some space, i.e. 148 bytes with GCC and 16 bytes with clang on x86 there are still some bytes left there though, and an acceptable hack which tricks the compiler into only using a 2-byte alignment instead of the native one when accessing the contents turned out to even take up more space that.

| | | | | | | | | | | | | | | | | | | | | | | - For Cheetah- and Zeus-class CPUs don't flush all unlocked entries from the TLBs in order to get rid of the user mappings but instead traverse them an flush only the latter like we also do for the Spitfire-class. Also flushing the unlocked kernel entries can cause instant faults which when called from within cpu_switch() are handled with the scheduler lock held which in turn can cause timeouts on the acquisition of the lock by other CPUs. This was easily seen with a 16-core V890 but occasionally also happened with 2-way machines. While at it, move the SPARC64-V support code entirely to zeus.c. This causes a little bit of duplication but is less confusing than partially using Cheetah-class bits for these. - For SPARC64-V ensure that 4-Mbyte page entries are stored in the 1024- entry, 2-way set associative TLB. - In {d,i}tlb_get_data_sun4u() turn off the interrupts in order to ensure that ASI_{D,I}TLB_DATA_ACCESS_REG actually are read twice back-to-back.

This driver was written by Alexander Pohoyda and greatly enhanced by Nikolay Denev. I don't have these hardwares but this driver was tested by Nikolay Denev and xclin. Because SiS didn't release data sheet for this controller, programming information came from Linux driver and OpenSolaris. Unlike other open source driver for SiS190/191, sge(4) takes full advantage of TX/RX checksum offloading and does not require additional copy operation in RX handler. The controller seems to have advanced offloading features like VLAN hardware tag insertion/stripping, TCP segmentation offload(TSO) as well as jumbo frame support but these features are not available yet.

| | | | | | | | | | | | | Some machines can not only consist of CPUs running at different speeds but also of different types, f.e. Sun Fire V890 can be equipped with a mix of UltraSPARC IV and IV+ CPUs, requiring different MMU initialization and different workarounds for model specific errata.

Unlike direct access the firmware methods don't automatically use the next free (?) TLB slot, instead the slot to be used has to be specified. We allocate the TLB slots for the kernel top-down as OpenSolaris suggests that the firmware will always allocate the ones for its own use bottom-up. Besides being simpler, according to OpenBSD using the firmware methods is required to allow booting on Sun Fire E10K with multi-systemboard domains. Notes: svn path=/stable/7/; revision=205923

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Assert that HEAPSZ is a multiple of PAGE_SIZE as at least the firmware of Sun Fire V1280 doesn't round up the size itself but instead lets claiming of non page-sized amounts of memory fail. - Change parameters and variables related to the TLB slots to unsigned which is more appropriate. - Search the whole OFW device tree instead of only the children of the root nexus device for the BSP as starting with UltraSPARC IV the 'cpu' nodes hang off of from 'cmp' (chip multi-threading processor) or 'core' or combinations thereof. Also in large UltraSPARC III based machines the 'cpu' nodes hang off of 'ssm' (scalable shared memory) nodes which group snooping-coherency domains together instead of directly from the nexus. - Add support for UltraSPARC IV and IV+ BSPs. Due to the fact that these are multi-core each CPU has two Fireplane config registers and thus the module/target ID has to be determined differently so the one specific to a certain core is used. Similarly, starting with UltraSPARC IV the individual cores use a different property in the OFW device tree to indicate the CPU/core ID as it no longer is in coincidence with the shared slot/socket ID. While at it additionally distinguish between CPUs with Fireplane and JBus interconnects as these also use slightly different sizes for the JBus/agent/module/target IDs. - Check the return value of init_heap(). This requires moving it after cons_probe() so we can panic when appropriate. This should be fine as the PowerPC OFW loader uses that order for quite some time now.
